All laboratory chemical use areas must maintain a work-area specific Chemical Hygiene Plan which conforms to the requirements of the OSHA Laboratory Standard 29 CFR 19190.1450. Morehead State University laboratories may use this document as a starting point for creating their work area specific Chemical Hygiene Plan (CHP).
Morehead State Chemical Hygiene Plan MSU Laboratory Awareness Certification
For CHP of (Professor, Building, Room)______
The Occupational Safety and Health Administration (OSHA) requires that laboratory employees be made aware of the Chemical Hygiene Plan at their place of employment (29 CFR 1910.1450). The Morehead State University Chemical Hygiene Plan and Hazardous Materials Safety Manual serves as the written Chemical Hygiene Plan (CHP) for laboratories using chemicals at Morehead State University. The CHP is a regular, continuing effort, not a standby or short term activity. Departments, divisions, sections, or other work units engaged in laboratory work whose hazards are not sufficiently covered in this written manual must customize it by adding their own sections as appropriate (e.g. standard operating procedures, emergency procedures, identifying activities requiring prior approval). After reading the "Morehead State Chemical Hygiene Plan and Hazardous Material Safety Manual," complete and return a copy of this form to your supervisor or to your department’s Safety Committee Chair. By signing below you acknowledge that you are aware of the Chemical Hygiene Plan and the policies and procedures applicable to the OSHA standard (29 CFR 1910.1450).

THE OSHA LABORATORY STANDARD
The basis for this standard (29 CFR 1910.1450) is a determination by the Occupational Safety and Health Administration (OSHA), after careful review of the complete rule-making record, that laboratories typically differ from industrial operations in their use and handling of hazardous chemicals and that a different approach than that found in OSHA's substance specific health standards is warranted to protect workers. The final standard applies to all laboratories that use hazardous chemicals in accordance with the definitions of laboratory use and laboratory scale provided in the standard. Generally, where this standard applies it supersedes the provisions of all other standards in 29 CFR, part 1910, subpart Z, except in specific instances identified by this standard. For laboratories covered by this standard, the obligation to maintain employee exposures at or below the permissible exposure limits (PELs) specified in 29 CFR, part 1910, subpart Z is retained. However, the manner in which this obligation is achieved will be determined by each employer through the formulation and implementation of a Chemical Hygiene Plan (CHP). The CHP must include the necessary work practices, procedures and policies to ensure that employees are protected from all potentially hazardous chemicals used or stored in their work area. Hazardous chemicals as defined by the final standard include not only chemicals regulated in 29 CFR part 1910, subpart Z, but also any chemical meeting the definition of hazardous chemical with respect to health hazards as defined in OSHA's Hazard Communication Standard, 29 CFR 1910.1200(c). Among other requirements, the final standard provides for employee training and information, medical consultation and examination, hazard identification, respirator use and record keeping. To the extent possible, the standard allows a large measure of flexibility in compliance methods. Effective Date: May 1, 1990. Compliance Date: Employers shall have completed an appropriate Chemical Hygiene Plan and commenced carrying out its provisions by January 31, 1991. Employers shall train all employees on the newly adopted Global Harmonized Standard (GHS) for chemical classification, Safety Data Sheets and labeling by December 1, 2013.
CULTURE OF SAFETY
With the promulgation of the Occupational Safety and Health Administration (OSHA) Laboratory standard (29 CFR 1910.1450), a culture of safety consciousness, accountability, organization, and education have developed in industrial, governmental, and academic laboratories. Safety and training programs have been implemented to promote the safe handling of chemicals from ordering to disposal, and to train laboratory personnel in safe practices. Laboratory personnel must realize that the welfare and safety of each individual depends on clearly defined attitudes of teamwork and personal responsibility. Learning to participate in this culture of habitual risk assessment, experiment planning, and consideration of worst-case possibilities—for oneself and one’s fellow workers—is as much part of a scientific education as learning the theoretical background of experiments or the step-by-step protocols for doing them in a professional manner. A crucial component of chemical education for all personnel is to nurture basic attitudes and habits of prudent behavior so that safety is a valued and inseparable part of all laboratory activities throughout their career.
MSU Chemical Hygiene Plan Page 8
Over the years, special techniques have been developed for handling chemicals safely. Local, state, and federal regulations hold institutions that sponsor chemical laboratories accountable for providing safe working environments. Beyond regulation, employers and scientists also hold themselves personally responsible for their own safety, the safety of their colleagues and the safety of the general public. A sound safety organization that is respected by all requires the participation and support of laboratory administrators, workers, and students. A successful health and safety program requires a daily commitment from everyone in the organization. To be most effective, safety and health must be balanced with, and incorporated into, laboratory processes. A strong safety and health culture is the result of positive workplace attitudes—from the chief executive officer to the newest hire; involvement and buy-in of all members of the workforce; mutual, meaningful, and measurable safety and health improvement goals; and policies and procedures that serve as reference tools, rather than obscure rules.
In order to perform their work in a prudent manner, laboratory personnel must consider the health, physical, and environmental hazards of the chemicals they plan to use in an experiment. However, the ability to accurately identify and assess laboratory hazards must be taught and encouraged through training and ongoing organizational support. This training must be at the core of every good health and safety program. For management to lead, personnel to assess worksite hazards, and hazards to be eliminated or controlled, everyone involved must be trained.
EMPLOYEE RIGHTS AND RESPONSIBILITIES
Employees have the right to be informed about the known physical and health hazards of the chemical substances in their work areas and to be properly trained to work safely with these substances. Employees have the right to file a complaint with OSHA if they feel they are being exposed to unsafe or unhealthy work conditions. Employees cannot be discharged, suspended, or otherwise discriminated against by their employer because of filing a complaint, or exercising their rights under the law. Employees have the responsibility to attend training workshops on the Laboratory Standard and Chemical Hygiene Plan and to stay informed about the chemicals used in their work areas. They have the responsibility to use safe work practices and protective equipment required for safe performance of their job. Finally they have the responsibility to inform their supervisors of accidents and conditions or work practices they believe to be a hazard to their health or to the health of others.
HAZARDOUS CHEMICALS
The Laboratory Standard defines a hazardous chemical as any element, chemical compound, or mixture of elements and/or compounds which is a physical or health hazard. In addition, the new Global Harmonized Standard (GHS) has classifications for health and physical hazards including the determination of the degree of hazard, where appropriate, by comparing the data with the criteria for health and physical hazards.
MSU Chemical Hygiene Plan Page 9
A chemical is a physical hazard if there is scientifically valid evidence that it is a flammable, a combustible liquid, a compressed gas, an explosive, an organic peroxide, an oxidizer, pyrophoric, unstable material (reactive), or water-reactive.
A chemical is a health hazard if there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees.
Hazard Classifications include (new in the GHS are in bold italics): Health & Environmental:
• Acute Toxicity • Aspiration Toxicity • Skin Corrosion/Irritation • Serious Eye Damage/Eye Irritation • Respiratory or Skin Sensitization • Germ Cell Mutagenicity • Carcinogenicity • Reproductive Toxicity • Target Organ Systemic Toxicity –Single and Repeated Dose • Hazardous to the Aquatic Environment/Aquatic Toxicity • Hazardous to the ozone layer
Physical Hazards:
• Explosives • Flammable –Gases, Aerosols Liquids, Solids • Oxidizers–liquids, solids, gases • Self-Reactive Substances • Self-Heating Substances • Pyrophoric –liquids, solids • Organic Peroxides • Corrosive to Metals • Gases Under Pressure • Water-Activated Flammable Gases
In most cases, the label will indicate if the chemical is hazardous. Look for key words like caution, hazardous, toxic, dangerous, corrosive, irritant, carcinogen, etc. The new GHS requires labels to have a pictogram outlined in red of the hazard(s). Some containers may have the NFPA
MSU Chemical Hygiene Plan Page 10
diamond to indicate hazards. Old containers of hazardous chemicals (before 1985) may not contain hazard warnings at all and should be properly relabeled by the Department. If you are not sure a chemical you are using is hazardous, review the Material Safety Data Sheet (MSDS) or contact your supervisor, instructor, or the Office of Environmental Health & Safety. Designated areas must be established and posted for work with certain chemicals and mixtures (Appendix G), which include select carcinogens, reproductive toxins, and/or substances which have a high degree of acute toxicity. A designated area may be the entire laboratory, an area of a laboratory or a device such as a laboratory hood. Those areas should be marked with a sticker or sign indicating the hazard, i.e. Radiation, Biohazard, etc.
MATERIAL SAFETY DATA SHEETS (MSDSs)
A Material Safety Data Sheet (MSDS) is a document containing chemical hazard and safe handling information prepared in accordance with the OSHA Hazard Communication Standard. Chemical manufacturers and distributors must provide a MSDS the first time a hazardous chemical/product is shipped to a facility. (Many manufacturers and distributors consider Morehead State University the facility.) All MSDS received must be retained and made available to laboratory workers through the Morehead State University MSDS Online Website. Any department having chemicals that are not on the website must forward a copy of the MSDS to the Office of Environmental Health & Safety so that it may be added. If you do not have a copy of an MSDS and cannot find it in the MSDS online system, contact the manufacturer or distributor and request a copy.
MSDS are to be kept for 30 years after the chemical is retired from use as per the OSHA Hazard Communication Standard. The MSDS Online system automatically updates each chemical MSDS if a manufacturer provides a revision/update and retains the old version in case of a complaint investigation or lawsuit. All MSDS will comply with the new GHS standard according to OSHA’s revised HCS. Access to the MSDS Online system is restricted to employees, students and others with a valid MSU ID# and password. You must log-in to myMSU, go to PRODUCTIVITY and then click Material Safety Data Sheets in the right-hand column. You may search chemicals by name, CAS #, manufacturer, and building/department location. The Hazard Communication Standard (HCS) requires chemical manufacturers, distributors, or importers to provide Safety Data Sheets (SDSs) (formerly known as Material Safety Data Sheets or MSDSs) to communicate the hazards of hazardous chemical products. As of June 1, 2015, the HCS will require new SDSs to be in a uniform format, and include the section numbers, the headings, and associated information under the headings below:

CHEMICAL PROCUREMENT • Information on proper handling, storage, and disposal should be known to those who will be involved before a substance is received. • Only containers with adequate identifying labels should be accepted. • Ideally, a central location should be used for receiving all chemical shipments. • Shipments with breakage or leakage should be refused or opened in a chemical hood. • Only the minimum amount of the chemical needed to perform the planned work should be ordered. • Purchases of high risk chemicals should be reviewed and approved by the CHO. See Appendix L for list. • Proper protective equipment and handling and storage procedures should be in place before receiving a shipment. • Chemical shipments should be dated upon receipt and stock rotated. • Peroxide formers should be dated upon receipt, again dated upon opening, and stored away from heat and light with tightfitting, nonmetal lids.
CHEMICAL INVENTORIES The OSHA Laboratory Standard does not require chemical inventories; however, it is prudent to adopt this practice. An annual inventory can reduce the number of unknowns and the tendency to stockpile chemicals. It is important to pay attention to dates of acquisition for chemicals that may become dangerous over a period of time. It is recommended that each department keep a detailed inventory of highly toxic chemicals and explosive/reactive materials. There should be a record of the date of receipt, amount, location, and responsible individual for all acquisitions, syntheses, and disposal of these chemicals. A physical inventory should be performed annually to verify active inventory records. There should be a procedure in place to report security breaches, inventory discrepancies, losses, diversions, or suspected thefts. The Department of Environmental Health & Safety may require that a chemical inventory be prepared for a room, work unit, or department. APPENDIX J contains a sample template for chemical inventories.
Any department or laboratory using chemicals in amounts greater than the reportable quantities on the EPCRA / CERCLA / CAA Consolidated List of lists (APPENDIX I) or Select Agents and Toxins List (APPENDIX L) must report those quantities annually in January to EHS. The list is updated periodically so check the EHS website for the latest version.
LABORATORY SECURITY Laboratory security has evolved in the past decade, reducing the likelihood of some emergencies and assisting in preparation and response for others. Most security measures are based on the laboratory’s vulnerability. Risks to laboratory security include, but are not limited to: (1) Theft or diversion of chemicals, biologicals, and radioactive or proprietary materials, mission-critical or high-value equipment; (2) Threats from activist groups; (3) Intentional release of, or exposure to, hazardous materials;
MSU Chemical Hygiene Plan Page 19
(4) Sabotage or vandalism of chemicals or high-value equipment; (5) Loss or release of sensitive information; and (6) Rogue work or unauthorized laboratory experimentation.
The following rules for security should be followed: • Laboratory and chemical storage areas must be kept locked when not in use. • Keyed access should be limited to those that work in the area as faculty and staff. Students should not be provided keys to laboratories or chemical storage areas. • Report all suspicious activity and behavior to the MSU Police department and/or Provost Office including threating verbal comments or physical threats from colleagues, students or staff. MSU Counseling Services is available to assist with a threat assessment of the situation. • Report all thefts, vandalism or potential sabotage of chemicals or laboratory equipment to MSU Police and the Director of Risk Management. • In the event of an active shooter in the building, keep the doors to laboratories and chemical storage areas locked until the Police clear the area.

MOREHEAD STATE UNIVERSITY CHEMICAL HYGIENE PLAN
This document serves as the written Chemical Hygiene Plan (CHP) for laboratories using chemicals at Morehead State University. The CHP is a regular, continuing effort, not a standby or short term activity. Departments, divisions, sections, or other work units engaged in laboratory work whose hazards are not sufficiently covered in this written manual must customize it by adding their own sections as appropriate (e.g. standard operating procedures, emergency procedures, identifying activities requiring prior approval).
SCOPE AND APPLICATION The CHP applies to all personnel at Morehead State University including regional campuses and the agricultural complex.
The CHP does not apply to: 1. Uses of hazardous chemicals which do not meet the definition of laboratory use. 2. Laboratory uses of hazardous chemicals which provide no potential for employee exposure.
Examples of such conditions might include: a. Procedures using chemically-impregnated test media such as Dip-and-Read tests where a reagent strip is dipped into the specimen to be tested and the results are interpreted by comparing the color reaction to a color chart supplied by the manufacturer of the test strip, and b. Commercially prepared kits such as those used in performing pregnancy tests in which all of the reagents needed to conduct the test are contained in the kit. Laboratory uses of chemicals not covered by the CHP are still subject to the full provisions of the OSHA Hazard Communication Standard and the MSU Right-to-Know Program.
RESPONSIBILITY
The MSU Office of Environmental Health & Safety (EHS) and the Chemical Safety Committee will develop the provisions of the CHP. The Chemical Safety Committee and EHS can establish health and safety work rules for work areas or departments. EHS and the Chemical Safety Committee may assign areas of responsibility to departments, department safety and health committees, supervisors, and other individuals, as necessary, to implement and carry out the provisions of the CHP.
President
The Morehead State University President is responsible for the Chemical Hygiene (Safety) for Morehead State University.

*While students are not covered under the provisions of the OSHA Laboratory Standard, students should be made aware of chemical health and safety hazards in classroom situations, and should be provided with information and equipment to protect themselves from those hazards. Departments should provide student training at the beginning of each course in which hazardous chemicals are used. Specific safety instructions should be provided at the beginning of each class period.
EXPOSURE LIMITS For laboratory uses of hazardous substances, departments must ensure that laboratory employees' exposures to such substances do not exceed either the permissible exposure limits (PELs) specified in 29 CFR 1910, subpart Z, which are set by the Occupational Safety and Health Administration (OSHA), or the Threshold Limit Values (TLVs) published by the American Conference of Governmental Industrial Hygienists (ACGIH), whichever is lower.
EMPLOYEE INFORMATION AND TRAINING
MSU Chemical Hygiene Plan Page 23
Departments must provide employees with information and training to ensure that they are knowledgeable of the hazards of chemicals present in their work area and the steps they should take to protect themselves from these hazards. Training may take the form of individual instruction, group seminars, audio-visual presentations, handout material, or any combination of the above. However, the training must include the specific hazards associated with the chemicals in the work area when generic training is insufficient (e.g., extremely toxic materials, carcinogens, reproductive hazards) to address specific hazards.
Such information must be provided at the time of an employee's initial assignment to a work area where hazardous chemicals are present and prior to assignment involving new exposure situations. Employees should receive periodic refresher information and training.
Note: Although the length of training is not specified in the OSHA regulations, effective information and training generally will take at least 2 hours for most laboratory scale operations.
The frequency of periodic refresher information and training will vary with the hazard; however, the length of time between training sessions should not exceed five years.
Information: Information provided by departments to employees must include: 1. The contents of the OSHA standard 29 CFR 1910.1450 and its appendices which shall be available to employees (available from MSU EHS online website); 2. The location and availability of the Morehead State University Chemical Hygiene Plan (available from MSU EHS online website); 3. The permissible exposure limits for OSHA regulated substances or published exposure limits for other hazardous chemicals where there is no applicable OSHA standard (available from MSU EHS online website under link to CDC (NIOSH) National Institute of Safety & Health Guide to Chemical Hazards); 4. Signs and symptoms associated with exposures to hazardous chemicals used in the laboratory (available on container labels and Material Safety Data Sheets); 5. The location and availability of known reference material on the hazards, safe handling, storage and disposal of hazardous chemicals found in the laboratory (see other applicable sections of this document; also available from EHS) including, but not limited to, Material Safety Data Sheets received from the supplier.
Training: Training provided by departments to employees must include: 1. Methods and observations that may be used to detect the presence or release of a hazardous chemical (such as monitoring conducted by the University, continuous monitoring devices, visual appearance or odor of hazardous chemicals when being released, etc.); 2. The physical and health hazards of chemicals in the work area; 3. The measures employees can take to protect themselves from these hazards, including
MSU Chemical Hygiene Plan Page 24 specific procedures the University or department has implemented to protect employees from exposure to hazardous chemicals, such as appropriate work practices, emergency procedures, and personal protective equipment to be used; 4. The applicable details of the Morehead State University Chemical Hygiene Plan.
Documentation: Awareness of the University CHP should be documented using the form on page 2 of this document. All CHP training records belonging to a department or other administrative unit should be held in a central administrative location (e.g., by Safety Committee Chair or in Department Head or Business Office), organized in any convenient manner provided the training record(s) for an individual, a research group, or department can be made immediately available during an OSHA inspection.
Basic Lab Safety Awareness Training from EHS: EHS offers an introductory Basic Lab Safety Awareness Training which is appropriate for laboratory chemical users of all experience levels. The overall training consists of a self-paced web based training on Blackboard that can be accessed under a search for OSHA on blackboard. This course will address the basics of lab safety, chemical labeling, chemical handling, personal protective equipment, safety information resources, laboratory housekeeping, safety equipment, waste management and disposal, and regulatory compliance.
MEDICAL CONSULTATIONS AND EXAMINATIONS In accordance with the OSHA standard, departments must provide all employees who work with hazardous chemicals an opportunity to receive medical attention, including any follow-up examinations which the examining physician determines to be necessary, under the following circumstances: 1. Whenever an employee develops signs or symptoms associated with a hazardous chemical to which the employee may have been exposed in the laboratory, the employee must be provided an opportunity to receive an appropriate examination. 2. Where exposure monitoring reveals an exposure level routinely above the action level (or in the absence of an action level, the PEL) for an OSHA regulated substance for which there are exposure monitoring and medical surveillance requirements, medical surveillance shall be established for the affected employee as prescribed by the particular standard. 3. Whenever an event takes place in the work area such as a spill, leak, explosion or other occurrence resulting in the likelihood of a hazardous exposure, the affected employee shall be provided an opportunity for a medical consultation. Such consultations shall be for the purpose of determining the need for a medical examination. All medical examinations and consultations must be performed by or under the direct supervision of a licensed physician and must be provided without cost to the employee, without loss of pay and at a reasonable time and place.
HAZARD IDENTIFICATION With respect to labels and Material Safety Data Sheets:
MSU Chemical Hygiene Plan Page 25
• Departments must ensure that labels on incoming containers of hazardous chemicals are not removed or defaced. • Departments must ensure that laboratory containers of chemicals are labeled where required. Laboratory containers, including bottles, flasks, sample vials, etc., must be marked, labeled, or coded in all cases. (If codes or markings other than chemical names are used, a code key or legend must be available in the workplace where it may be found quickly and easily by emergency responders or other interested parties.) Labels should bear a date of receipt and should identify the owner of the material. • Departments must ensure that any Material Safety Data Sheets that are received with incoming shipments of hazardous chemicals are in the MSU MSDS Online system. If they are not in the system, departments must forward the MSDS to EHS personnel to add to the system immediately. This will ensure that the MSDS is available to laboratory employees and emergency responders at all times. • Departments may keep a binder of their own MSDS in the laboratory or other convenient location but that may not replace the requirement for the MSDS to be in the MSU MSDS Online system. • LABELS: Labels should follow the new GHS guidelines (sample label in Appendix **) including: 1. Pictogram: a symbol plus other graphic elements, such as a border, background pattern, or color that is intended to convey specific information about the hazards of a chemical. Each pictogram consists of a different symbol on a white background within a red square frame set on a point (i.e. a red diamond). There are nine pictograms under the GHS. However, only eight pictograms are required under the HCS. 2. Signal words: a single word used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label. The signal words used are "danger" and "warning." "Danger" is used for the more severe hazards, while "warning" is used for less severe hazards. 3. Hazard Statement: a statement assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical, including, where appropriate, the degree of hazard. 4. Precautionary Statement: a phrase that describes recommended measures to be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling of a hazardous chemical.
CHEMICALS DEVELOPED IN THE LABORATORY The following requirements apply to chemical substances developed in the laboratory: 1) If the composition of the chemical substance which is produced exclusively for the laboratory's use is known, the laboratory supervisor must determine if it is a hazardous chemical (e.g., by literature search). If the chemical is determined to be hazardous, the laboratory supervisor must provide appropriate training to protect employees.
MSU Chemical Hygiene Plan Page 26
2) If the chemical produced is a by-product whose composition is not known, the laboratory supervisor must assume that the substance is hazardous and must comply with the requirements of the CHP. 3) If the chemical substance is produced for another user outside of the laboratory, the Laboratory supervisor must comply with the Hazard Communication Standard (29 CFR 1910.1200) including the requirements for preparation of Material Safety Data Sheets and labeling. Note: Item 1 does not require the laboratory supervisor to conduct toxicological testing. However, if a Material Safety Data Sheet or hazard information is available for the chemical, the information must be made available to employees.
USE OF RESPIRATORS Where the use of respirators is necessary to maintain exposure below permissible exposure limits (PELs) or the Threshold Value Limits (TLVs), whichever is lower, the department must provide, at no cost to the employee, the proper respiratory protective equipment. Respirators must be selected and used in accordance with the requirements of the Morehead State University Respiratory Protection Program (located on EHS website under MSU Safety Guidelines or contact EHS for additional information).
STANDARD OPERATING PROCEDURES The Chemical Safety Committee and the Chemical Hygiene Officer will develop generic standard operating procedures relevant to safety and health considerations to be followed when laboratory work involves the use of hazardous chemicals. Departments, department safety and health committees, and supervisors will develop written standard operating procedures for work area specific operations. See appendix K for an example. Standard operating procedures must be provided to affected employees. For work involving extremely toxic chemicals, select carcinogens, and reproductive toxins, standard operating procedures must include the following provisions where appropriate: 1. Establishment of a designated area; 2. Use of containment devices such as fume hoods or glove boxes; 3. Procedures for safe removal of contaminated waste; and 4. Decontamination procedures.
CONTROL MEASURES Whenever employee exposures exceed the action level (or in the absence of an action level, the lower of the PEL or TLV), the department must implement control measures to reduce employee exposure to hazardous chemicals including engineering controls, the use of personal protective equipment and hygiene practices. Exposures to extremely toxic materials, select carcinogens, and reproductive toxins must be maintained as low as reasonably achievable.
PROTECTIVE EQUIPMENT Users of hazardous chemicals are responsible for determining that fume hoods and other protective equipment is adjusted and functioning properly prior to initiating an activity requiring their use. All fume hood installations include a continuous monitoring device to allow
MSU Chemical Hygiene Plan Page 27
users to monitor hood performance. EHS will survey chemical fume hoods semi-annually and notify the department of the need for repairs when necessary. Call EHS or Facilities Management if you have questions or wish to report a problem.
SPECIAL HAZARDS The Laboratory Supervisor will define which if any activities, operations, or procedures constitute circumstances under which prior approval must be obtained by employees before implementation. Note: OSHA requires each employer to identify those activities which the employer believes to be of a sufficiently hazardous nature to warrant prior "employer approval" before implementation. The Chemical Hygiene Plan identifies activities which involve extremely toxic chemicals, select carcinogens and reproductive hazards, and those activities with a high potential for personal injury and property damage. Supervisors will need to determine if any other existing activities are subject to the requirements of this section. Except for activities identified by the Chemical Safety Committee as requiring Committee approval, "employer approval" will occur at the local level (e.g., Supervisor, Department Head, Department Safety and Health Committee). The Chemical Hygiene Officer is available for assistance.
Availability The Chemical Hygiene Plan must be readily available to employees and employee representatives. The Chemical Hygiene Plan is available on the MSU EHS webpage.
ANNUAL REVIEW The Chemical Safety Committee is responsible for preparing an annual review of the Chemical Hygiene Plan. The review process will utilize such resources as results of internal and external audits, accident reports, notices of violation, customer satisfaction surveys, and other information and tracking reports which may become available. The focus of the annual review is to evaluate program effectiveness and to identify strengths, weaknesses or new regulations which may be updated to improve the program.

PART II HAZARDOUS MATERIALS SAFE HANDLING INFORMATION
MSU Chemical Hygiene Plan Page 29
Minimize All Chemical Exposures and Risks
Because few laboratory chemicals are without hazards, general precautions for handling all laboratory chemicals should be adopted. In addition to these general guidelines, specific guidelines for chemicals that are used frequently or are particularly hazardous should be adopted.
Laboratory personnel should conduct their work under conditions that minimize the risks from both known and unknown hazardous substances. Before beginning any laboratory work, the hazards and risks associated with an experiment or activity should be determined and the necessary safety precautions implemented. Every laboratory should develop facility- specific policies and procedures for the highest-risk materials and procedures used in their laboratory. To identify these, consideration should be given to past accidents, process conditions, chemicals used in large volumes, and particularly hazardous chemicals.
Perform Risk Assessments for Hazardous Chemicals and Procedures Prior to Laboratory Work:
(a) Identify chemicals to be used, amounts required, and circumstances of use in the experiment. Consider any special employee or laboratory conditions that could create or increase a hazard. Consult sources of safety and health information and experienced scientists to ensure that those conducting the risk assessment have sufficient expertise.
(b) Evaluate the hazards posed by the chemicals and the experimental conditions. The evaluation should cover toxic, physical, reactive, flammable, explosive, radiation, and biological hazards, as well as any other potential hazards posed by the chemicals.
(c) For a variety of physical and chemical reasons, reaction scale-ups pose special risks, which merit additional prior review and precautions.
(d) Select appropriate controls to minimize risk, including use of engineering controls, administrative controls, and personal protective equipment (PPE) to protect workers from hazards. The controls must ensure that OSHA’s Permissible Exposure Limits (PELs) are not exceeded. Prepare for contingencies and be aware of the institutional procedures in the event of emergencies and accidents.
One sample approach to risk assessment is to answer these five questions:
(a) What are the hazards?
(b) What is the worst thing that could happen?
(c) What can be done to prevent this from happening?
MSU Chemical Hygiene Plan Page 30
(d) What can be done to protect from these hazards?
(e) What should be done if something goes wrong?
Avoid Underestimation of Risk
Even for substances of no known significant hazard; exposure should be minimized; when working with substances that present special hazards, special precautions should be taken. Reference should be made to the material safety data sheet (MSDS) that is provided for each chemical. Unless otherwise known, one should assume that any mixture will be more toxic than its most toxic component and that all substances of unknown toxicity are toxic.
Determine the physical and health hazards associated with chemicals before working with them. This determination may involve consulting literature references, laboratory chemical safety summaries (LCSSs), SDSs, or other reference materials. Consider how the chemicals will be processed and determine whether the changing states or forms will change the nature of the hazard. Review your plan, operating limits, chemical evaluations and detailed risk assessment with other chemists, especially those with experience with similar materials and protocols.
Before working with chemicals, know your facility’s policies and procedures for how to handle an accidental spill or fire. Emergency telephone numbers should be posted in a prominent area. Know the location of all safety equipment and the nearest fire alarm and telephone.
Adhere to the Hierarchy of Controls
The hierarchy of controls prioritizes intervention strategies based on the premise that the best way to control a hazard is to systematically remove it from the workplace, rather than relying on employees to reduce their exposure. The types of measures that may be used to protect employees (listed from most effective to least effective) are: engineering controls, administrative controls, work practices, and PPE. Engineering controls, such as chemical hoods, physically separate the employee from the hazard. Administrative controls, such as employee scheduling, are established by management to help minimize the employees’ exposure time to hazardous chemicals. Work practice controls are tasks that are performed in a designated way to minimize or eliminate hazards. Personal protective equipment and apparel are additional protection provided under special circumstances and when exposure is unavoidable.
Face and eye protection is necessary to prevent eye contact, ingestion, and skin absorption of hazardous chemicals. At a minimum, safety glasses, with side shields, should be used for all laboratory work. Chemical splash goggles are more appropriate than regular safety glasses to protect against hazards such as chemical splashes, projectiles, as well as when working with glassware under reduced or elevated pressures (e.g., sealed tube reactions),
MSU Chemical Hygiene Plan Page 31
when handling potentially explosive compounds (particularly during distillations), and when using glassware in high-temperature operations. Do not allow laboratory chemicals to come in contact with skin. Select gloves carefully to ensure that they are impervious to the chemicals being used and are of correct thickness to allow reasonable dexterity while also ensuring adequate barrier protection.
Lab coats and/or aprons and gloves should be worn when working with hazardous materials in a laboratory. Wear closed-toe shoes and long pants or other clothing that covers the legs when in a laboratory where hazardous chemicals are used. Additional protective clothing should be used when there is significant potential for skin-contact exposure to chemicals. The protective characteristics of this clothing must be matched to the hazard. Never wear gloves or laboratory coats outside the laboratory or into areas where food is stored and consumed.
SAFE HANDLING OF CHEMICALS Know the physical and health hazards associated with the chemical(s) you are using. Consider the physical state (gas, liquid, or solid) of the material(s). Consider the process in which you are using the chemical(s), the facilities you have for storage of the materials, and the facilities and equipment you may need to handle an emergency. Know the procedures necessary for safe disposal of the chemicals. Questions you should consider: 1. Is the material flammable, explosive, corrosive, or reactive? 2. Is the material toxic, and if so, how can I be exposed to the material (inhalation, skin or eye contact, accidental ingestion, accidental puncture)? 3. What kind of ventilation do I need to protect myself? What kind of personal protective equipment (i.e. gloves, respirator, goggles) do I need to protect myself? 4. Will the process generate other toxic compounds, or could it result in a fire, explosion, etc.? 5. Are my storage facilities appropriate for the type of materials I will be using? Can I properly segregate incompatible materials? 6. What possible accidents can occur and what steps can I take to minimize the likelihood and impact of an accident? 7. What are the proper procedures for disposal of the chemical(s)?
Once you evaluate the potential hazards associated with the chemical(s) and the process, you can design your process and work procedures to minimize or eliminate the hazards. The following sections provide work procedures and engineering controls which can be used to minimize or eliminate hazards in the laboratory.
GENERAL SAFETY GUIDELINES Know the hazards associated with the materials you are using. Carefully read the label before using a chemical. Review the Material Safety Data Sheet (MSDS) for any special handling information. In some cases it may be necessary to do additional research.
MSU Chemical Hygiene Plan Page 32
Be prepared for hazardous material emergencies and know what action to take in the event of an emergency. Be certain that necessary supplies and equipment are available for handling small spills of hazardous materials. Know the location of safety equipment: emergency shower, eye wash, fire extinguisher, fire alarm pull station and spill control station.
Do not work alone in the laboratory if you are working with hazardous materials. Limit access to areas where chemicals are used or stored by posting signs and/or locking doors when areas are unattended. Do not permit children in the laboratory.
Purchase the minimum amount of hazardous materials necessary to accomplish your work and dispense only the minimum amount necessary for immediate use.
Use hazardous chemicals only as directed and for their intended purpose.
Never smell or taste a hazardous chemical.
Vent apparatus which may discharge toxic chemicals (vacuum pumps, distillation columns, etc.) into local exhaust devices.
Inspect gloves and all other personal protective equipment before use.
On equipment such as hoods and biosafety cabinets, be familiar with the certification date or "to be tested again" date given on the test sticker.
Inspect equipment or apparatus for damage before adding a hazardous chemical or beginning a hazardous procedure. Do not use damaged equipment.
Glass vacuum lines, pressure lines and Dewar flasks should be taped or caged.
Ensure that ventilation is adequate for the materials used. Refer to the MSDS for information on ventilation requirements. See the "Engineering Controls" section of this booklet.
Avoid direct contact with any chemical. Keep chemicals off hands, face and clothing, including shoes.
Avoid practical jokes or other behavior which might confuse, startle or distract another worker.
Confine long hair and loose clothing. Wear shoes at all times in the laboratory, but do not wear sandals, flip flops or perforated shoes.
Keep the work area clean and uncluttered with chemicals and equipment. Clean up the work area on completion of an operation or at the end of each work day.
MSU Chemical Hygiene Plan Page 33
Use required personal protective equipment. See the "Personal Protective Equipment" section of this booklet. Remove laboratory coats immediately on significant contamination.
Label all secondary containers with appropriate hazard information. Make sure that labels on primary and secondary containers do not become damaged. Replace them when necessary.
Use good hygiene. Keep your hands and face clean. Wash thoroughly with soap and water after handling any chemical.
Smoking, drinking, eating, and the application of cosmetics are forbidden in areas where hazardous chemicals are in use.
Do not store food or drink for human consumption, or utensils or equipment for preparing food or drink, in the same cabinet, drawer, refrigerator or freezer with chemicals or equipment used with laboratory chemicals.
Never use mouth suction to fill a pipette.
Electrically ground and bond containers using approved methods before transferring or dispensing a flammable liquid from a large container.
Promptly clean up spills, using appropriate protective apparel, equipment and procedures. See the "Emergency Response" section of the booklet.
Ensure that adequate storage facilities and containers are provided for hazardous materials. See the "Chemical Storage" section of this booklet.
Ensure that hazardous materials are properly segregated into compatible categories. See the "Chemical Storage" section of this booklet.
For unattended operations, leave lights on, place an appropriate sign on the door, and provide for containment of toxic substances in the event of a utility service failure (e.g., loss of cooling water). Plans to conduct unattended operations should be reviewed with the laboratory supervisor.
For specific information regarding chemical handling, contact your supervisor, instructor, or EHS.
ENGINEERING CONTROLS Exposure to hazardous materials should be controlled to the greatest extent feasible by use of engineering controls. For assistance in determining engineering controls necessary for your work situation, contact EHS. Engineering controls to reduce or eliminate exposures to hazardous chemicals include:
MSU Chemical Hygiene Plan Page 34
• substitution of less hazardous equipment, chemical or process (e.g., safety cans for glass bottles) • isolation of the operator or the process (e.g., use of barriers when handling explosives, or completely enclosing process in glove box or other enclosure) • local and general exhaust ventilation (e.g., use of fume hoods) Ventilation Controls: To determine ventilation requirements, check the MSDS. Expressions on an MSDS such as those listed below indicate a need for ventilation: • use with adequate ventilation • avoid vapor inhalation • use in a fume hood • provide local exhaust ventilation Ventilation recommendations must be adapted to the worksite and the specific process.
Proper Use of Ventilation Systems. As a rule of thumb, use a hood or other local ventilation device when working with any volatile substance. Once a ventilation system is installed in a work area, it must be used properly to be effective. The objective of a local exhaust ventilation system is to draw hazardous materials in the air away from the breathing zone of the employee. The system must be checked prior to each use to determine that it is operating. If the system is not working, it should be posted out of order and the Building Supervisor should be contacted to put in a work order and have the system repaired. Do not work with hazardous materials if the required ventilation system is not working. Ventilation systems must be properly configured. Be sure you know how to properly use the system in your area for the work you are doing. For use of laboratory fume hoods, the following guidelines should be followed:
1) Fume hoods should be marked to indicate proper sash position for optimum hood performance. The hood sash should be set at this point for procedures which could generate toxic aerosols, gases or vapors. If it is not possible to do work with the sash height set at the point marked, or if there is no marking on the hood, contact EHS. In general, the sash height should be set at a level where the operator is shielded to some degree from any explosions or violent reactions which could occur and where optimum air flow dynamics are achieved. Most fume hoods are not intended to be used with the sash fully open. 2) Fume hoods should be equipped with a manometer or other continuous reading monitoring device to indicate adequacy of flow. Learn how to read and interpret this gauge, and check it daily. If the gauge indicates a reduced flow in the hood, post the hood out of order and contact the Building Supervisor to have the hood repaired. 3) Only apparatus and chemicals essential to the specific procedure or process should be placed in the hood. Extraneous materials from previous experiments or procedures should be removed and stored in a safe location outside the hood. Hoods used for experimental work should not be used for chemical or material storage. Hoods used for chemical storage should be dedicated to chemical storage. No experimental work
MSU Chemical Hygiene Plan Page 35
should be conducted in these hoods. If there are any questions concerning the adequacy of a fume hood or the procedures for safe use of a fume hood, contact EHS.
FUME HOOD GUIDELINES
1) Before using a fume hood, ensure you will be provided with an appropriate level of protection and that the fume hood is appropriate for your work. Ensure the hood is turned on before starting your work.
2) All fume hoods should have an “Air Flow Indicator”, either a digital display or flow ribbon. Prior to starting work in a fume hood, check that the digital display reads 85 to 115 fpm or, when appropriate, the ribbon to make sure air is flowing into the hood (ribbon should be angled towards the hood).
3) Keep all apparatus at least ten inches from the front face of the fume hood and six inches from the back damper to ensure air is adequately drawn into the hood. Items stored at the back of the fume hood and larger items should be elevated on a shelf.
4) Clearly label all chemicals and long-term experiments including the user’s name and date.
5) To prevent a reduction in airflow at the face of the hood, limit the number of individuals standing close to the fume hood and ensure that open doors and windows are not creating a cross draft.
6) If a power outage occurs, fume hood function will likely be compromised. In this situation, take precautions to ensure adequate protection.
7) Do not place electrical apparatus or other ignition sources inside the fume hood when flammable liquids or gases are present in the hood.
8) Do not use a hood for storing chemicals unless it has been designated for storage.
9) Before turning the hood off, ensure that any chemical storage will not be affected.
If you suspect a reduction or loss of air flow, close fume hood sash and notify your lab instructor. Also notify others working in the lab. For more information, please contact EHS (3- 2179).
MSU Chemical Hygiene Plan Page 36
ADMINISTRATIVE CONTROLS Administrative controls are procedural measures which can be taken to reduce or eliminate hazards associated with the use of hazardous materials.
Administrative controls include the following: • Careful planning of experiments and procedures with safety in mind. Planning includes the development of written work procedures for safe performance of the work. • Restricting access to areas in which hazardous materials are used. • Using signs or placards to identify hazardous areas (designated areas). • Use of labels on hazardous materials. • Substitution of less toxic materials for toxic materials. • Good housekeeping. • Good hygiene (e.g., washing hands and other areas of possible chemical contact). • Prohibiting the storage and preparation of food in areas where chemicals are used or stored. • Prohibiting eating, drinking, and smoking where chemicals are used or stored, and providing break areas for this purpose. • No mouth pipetting. • Adding acid (or caustic) to water, never water to acid (or caustic). • Ensuring that employees are provided adequate training for safe work with hazardous materials.
SIGNAGE
Prominent signs of the following types should be posted:
• Emergency telephone numbers of emergency personnel/facilities, supervisors, and laboratory workers; • Location signs for safety showers, eyewash stations, other safety and first aid equipment, and exits; and • Warnings at areas or equipment where special or unusual hazards exist.
Restricted access areas: Facilities placarded with any of the following or similar warning signs are to be regarded as restricted access areas: • CAUTION - BIOHAZARD • CAUTION - CARCINOGENS, REPRODUCTIVE TOXINS, OR OTHER EXTREMELY TOXIC CHEMICALS • CAUTION - RADIOACTIVE MATERIAL • CAUTION - RADIATION AREA • CAUTION - X-RAY • CAUTION – LASER
Such areas and are not to be entered except by authorized users of the facility and those
MSU Chemical Hygiene Plan Page 37
having permission from authorized users. Children are never permitted in restricted access areas. (See below for considerations relating to Building Services and other support staff.)
Custodians are permitted to enter restricted areas to perform routine tasks; however, custodians should not touch containers of chemicals (including waste) or other research equipment or materials. Laboratory custodial staff should attend proper training.
Other support personnel, such as University Police and Safety and Security personnel, are permitted to enter restricted areas provided the work to be performed does not involve disturbing a use area within the facility, equipment, or materials. Examples include: • fume hoods • biological safety cabinets • sinks • placarded equipment • chemical or materials in lab • benches Support personnel should contact an authorized user of the facility or EHS before performing work which may involve any of the above items.
Immediately notify the University Police (See cover page) of any emergency or unusual conditions such as: • spills • contamination • leaks • injury • fires For additional information concerning restricted access areas, contact your supervisor, instructor or EHS.
PERSONAL PROTECTIVE EQUIPMENT General Considerations. Personal protective devices may be needed to supplement available engineering controls, but are never used as a substitute for engineering controls except as a temporary measure while such controls are being instituted or for short term jobs where the implementation of engineering controls is not feasible. The MSDS will provide some information on the personal protective equipment recommended for use with the chemical. The MSDS addresses "worst case" conditions; therefore, all the equipment described may not be necessary for a specific job. In addition, the MSDS may not provide sufficient information concerning a specific respirator or type of glove appropriate for the chemical.
Hazards Assessments. The supervisor is responsible for determining which personal protective devices are required for each task performed by employees. This is accomplished by performing a hazards assessment, documenting it on a form, and posting the completed hazards assessment certification in the work area. There is no harm in being over protected, but the
MSU Chemical Hygiene Plan Page 38 minimal requirements are to be spelled out by the hazards assessments. Departments must provide required personal protective equipment to employees, and supervisors must ensure that employees are trained in all necessary aspects of its proper use and care. This training must be documented. Failure to prescribe, provide, and properly use required personal protective equipment can result in personal injury and disciplinary action.
Protection Against Inhalation Hazards. When ventilation is not adequate to provide protection against an inhalation hazard, respiratory protective equipment may be necessary. There is a variety of respiratory protective equipment available for use, but no one device will provide protection against all possible hazards. Respirator selection is based on the chemical and process hazard, and the protection factors required. Respirators are not to be used except in conjunction with a comprehensive respiratory protection program. Such a program includes a review of the process to ensure that proper equipment is selected for the job; training of all respiratory protective equipment users concerning the methods for proper use and care of such equipment; fitting of respirator users when required; and medical surveillance of respirator users when required. Types of respiratory protective equipment include: • particle-removing air-purifying respirators • gas and vapor-removing air-purifying respirators • atmosphere-supplying respirators If your work requires the use of a respirator or you suspect your work requires the use of a respirator, you should contact your supervisor. He/she will contact EHS for an evaluation of the exposure and will schedule a medical physical examination to determine that you are physically fit to wear respiratory protection, and respirator fit-testing and training. Do not use respiratory protective equipment until you have received proper training. If you are currently using a respirator and you have not received training in its use and care, contact EHS immediately. In some cases, respiratory protective equipment may be kept on-hand for an emergency. In this situation, all potential users must receive training in its use. In addition, the equipment must be inspected on a monthly basis and this inspection must be documented. If you have respiratory protective equipment on-hand for use in an emergency and you have not received training in its use and care, contact EHS immediately. For more information on the Morehead State University Respiratory Protection Program, contact EHS.
Protection of Skin and Body. Skin and body protection involves the use of protective clothing to protect various parts of the body. Eye and face injuries are prevented by the use of the following: • safety glasses with side shields for dust and flying object hazards • splash-proof goggles for chemical splash, spray and mist hazards • full-face and neck shields for head and neck protection from various hazards (must be used with safety glasses or goggles) *Splash-proof goggles provide superior protection against dust, flying objects, and splash, spray and mist hazards. They should be the first choice for primary eye protection.
MSU Chemical Hygiene Plan Page 39
Cover all unprotected skin surfaces. Do not wear open-toe shoes, sandals, shorts, etc. in a chemical laboratory.
Even when there is minimal danger of skin contact with a hazardous substance, lab coats, coveralls, aprons, or protective suits should be used. General categories of contaminants include: • toxic dusts (e.g. asbestos) • bacteriological agents • lab chemicals • radioactive materials
Garments contaminated with hazardous materials should not be taken home by staff for laundering. They should be laundered on-site or by a commercial laundry which has been notified of potential hazards.
For heavily contaminated work, special attention must be given to sealing all openings in the clothing. Tape can be utilized for this purpose. Caps should be worn to protect hair from contamination.
Exposures to strong acids and acid gases, organic chemicals and strong oxidizing agents, carcinogens, and mutagens require the use of protective equipment that prevents skin contamination. Impervious protective equipment must be utilized. Examples include: • rubber gloves • rubber boots • rubberized suits • special protective equipment
Protective garments are not equally effective for every hazardous chemical. Some chemicals will "break through" the garment in a very short time; therefore, garment selection is based on the specific chemical utilized.
CONTAMINATED CLOTHING AND PROTECTIVE EQUIPMENT Where splash or spill of hazardous chemicals on clothing or protective equipment occurs, the clothing/equipment should be removed and placed in a closed container which prevents dispersion of the hazardous chemical. The clothing/equipment should be disposed of, cleaned, or laundered as appropriate. Employees should not take contaminated clothing/equipment home for cleaning or laundering. Persons or companies cleaning or laundering contaminated clothing or equipment must be informed of the potentially harmful effects of exposure to the chemical contaminant and must be advised of the measures necessary to protect themselves.
MSU Chemical Hygiene Plan Page 40
EMERGENCY SHOWER & EYEWASH STATIONS KY OSHA requires that “where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.” • Must be located within 10 seconds of potential exposure area. • Must be tested annually (by EHS) and activated monthly (by Laboratory Supervisor or supervisor’s assignee). • Must keep a written log of tests and activations. • Laboratory supervisors are responsible for monthly activations.
*Anytime a shower or eye wash is activated due to an exposure, you must call MSU dispatch and EHS. The employee or student must be seen by an emergency care physician. An accident report should be completed and submitted to EHS. If the accident involves an employee, it should be reported to Human Resources as soon as possible.
CHEMICAL STORAGE • Carefully read the label before storing a hazardous chemical. The MSDS will provide any special storage information and incompatibilities. • Ensure all containers are in good condition and properly labeled. • Do not store unsegregated chemicals in alphabetical order. • Do not store incompatible chemicals in close proximity to each other.
Whenever possible, separate chemicals into the following general hazard classes: • Flammable/combustible liquids • Flammable solids • Mineral acids • Organic acids (liquid) • Caustics • Oxidizers • Perchloric acid • Water-reactive • Air-reactive • Heat-reactive (require refrigeration) • Unstable (shock-sensitive, explosive) • Others • Gases: -toxic -flammable -oxidizers and inert • NEVER store the following types of chemicals & wastes near each other: – Acids and bases. – Organics and acids. – Cyanide, sulfide or arsenic compounds and acids.
MSU Chemical Hygiene Plan Page 41
– Alkali or alkali earth metals, alkyllithiums etc. and aqueous waste. – Powdered or reactive metals and combustible materials. – Mercury or silver and ammonium containing compounds.
• Once separated into hazard classes, chemicals may be stored alphabetically. • Determine what equipment and space is needed for safe storage of chemicals. • Except when material is being transferred, keep chemical containers tightly closed. • Use approved storage cabinets, containers, and safety cans for flammable liquids. • Refrigerators and freezers used for the storage of chemicals or other laboratory supplies must be posted “No flammables or combustibles” if they have internal sources of ignition. • Do not store chemicals on refrigerator door shelves. Containers could fall when the door is opened or closed. • Refrigerators for storage of food (for staff lunches, etc.) must be marked "FOOD ONLY, NO LABORATORY CHEMICALS OR LAB SUPPLIES." • Do not store food, beverages, or food/beverage preparation supplies or equipment in an area (cabinet, shelf, refrigerator, drawer) that is used for storage of chemicals or equipment used in chemical work. • Flammable liquids stored in glass containers shall not exceed 1 quart (liter). Exception: For conditions where chemical purity must be protected, flammable liquids stored in glass containers shall not exceed 1 gallon (4 liters). • Corrosion resistant cabinets are recommended for storage of corrosives. • Use spill trays under containers of reagents which can cause spill problems. • Dispose of old chemicals promptly. • Recycle excess chemicals no longer being used in your area if possible. • Do not store chemical liquids or solids above eye level. • Chemical storage and handling rooms should be controlled-access areas. They should have proper ventilation, appropriate signage, diked floors, and fire suppression systems. • For more information on chemical storage, contact your supervisor, instructor, or EHS.
TRANSFERING CHEMICALS
(a) Use adequate ventilation (such as a fume hood) when transferring even a small amount of a particularly hazardous substance (PHS). (b) While drum storage is not appropriate for laboratories, chemical stockrooms may purchase drum quantities of solvents used in high volumes. Ground and bond the drum and receiving vessel when transferring flammable liquids from a drum to prevent static charge buildup. (c) If chemicals from commercial sources are repackaged into transfer vessels, the new containers should be labeled with all essential information on the original container.
MSU Chemical Hygiene Plan Page 42
MODEL WRITTEN STANDARD OPERATING PROCEDURES SPECIAL PRECAUTIONS FOR WORKING WITH HAZARDOUS CHEMICALS The Laboratory Standard defines a hazardous chemical as any element, chemical compound, or mixture of elements and/or compounds which is a physical hazard or a health hazard. The standard also requires the employer to develop the circumstances under which a particular laboratory operation, procedures or activity shall require prior approval from the employer before implementation. The Laboratory Supervisor will define which if any activities, operations, or procedures constitute circumstances under which prior approval must be obtained by employees before implementation. Except for activities identified by the Chemical Safety Committee as requiring Committee approval, employer approval will occur at the local level (e.g., Supervisor, Department Head, Department Safety and Health Committee). The Chemical Hygiene Officer is available for assistance. The special precautions described in the following sections are to be used in conjunction with the information detailed in the "General Safety Guidelines." The special precautions sections and any other relevant instructions in this Chemical Hygiene Plan Manual may be used as part of the written standard operating procedures required by the OSHA Laboratory Standard. Project-specific and/or area-specific standard operating procedures must be written and attached in the Appendix by departments, laboratory supervisors, work units, or project directors for hazardous chemical and hazardous operations work not covered by the following special precautions sections.
PHYSICAL HAZARDS "Physical hazard" refers to a chemical for which there is evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive. Materials which present a physical hazard can be safely used if the specific hazard(s) are understood, and measures are taken to address the hazards. If appropriate precautions are not taken, a fire, an explosion, unwanted corrosion, personal injury, or property damage could occur.
Certain chemicals cannot be safely mixed or stored with other chemicals because a severe reaction can take place or an extremely toxic reaction product can result. See Appendix B for a table of incompatible chemicals.
An eyewash and safety shower must be readily accessible to areas where injurious materials are used and stored. In the event of skin or eye contact with an injurious material, immediately flush the area of contact with cool water for 15 minutes. Remove all affected clothing. Get medical help. Additional information concerning eyewash and safety shower requirements is available from EHS.

MODEL WRITTEN SOP -- The OSHA Laboratory Standard explicitly requires "standard operating procedures relevant to safety and health considerations to be followed when laboratory work involves the use of hazardous chemicals." If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Flammables and Combustibles: Flammable/combustible materials are materials which under standard conditions can generate sufficient vapor to cause a fire in the presence of an ignition source. Flammable materials can generate sufficient vapors at temperatures below 100oF (38oC); combustibles, at temperatures at or above 100oF (38oC) and below 140oF (60oC). The vapors of these materials are invisible, and a vapor trail to an ignition source away from the immediate area can result in a flashback. Flammables are more hazardous at elevated temperatures due to more rapid vaporization. In addition, flammable and combustible materials react with oxidizers which can result in a fire. Observe the following special precautions.
1. Eliminate ignition sources such as open flames, smoking materials, hot surfaces, sparks from welding or cutting, operation of electrical equipment, and static electricity. Post conspicuous "No Smoking" signs in areas where flammable materials are used or stored. 2. Minimize the quantity kept in the work area. 3. Store in approved flammable liquid containers (safety cans) and storage cabinets, or in a special storage room designed for that purpose. 4. Store away from oxidizers. 5. Flammable liquids stored in glass containers shall not exceed 1 quart. Exception: For conditions where chemical purity must be protected, flammable liquids stored in glass containers shall not exceed 1 gallon. 6. Refrigerators and freezers used for the storage of flammable or combustible liquids must have no internal sources of ignition (lab-safe). 7. Ensure that there is proper bonding and grounding when it is required, such as when transferring or dispensing a flammable liquid from a large container or drum. Bonding and grounding must be checked regularly. 8. Ensure that appropriate fire control systems or extinguishers are available.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Corrosives: The term “corrosive” refers to substances that rapidly attack the skin, eyes and other living tissues. Corrosives can react with the skin causing burns similar to thermal burns, and/or which can react with metal causing deterioration of the metal surface. Inhaling vapors can cause severe bronchial irritation or pulmonary edema. Such chemicals commonly include strong acids or bases, dehydrating agents and oxidizing agents. Examples include: ACIDS BASES DEHYDRATING OXIDIZING Sulfuric Sodium Hydroxide Sulfuric Acid Picric Acid Nitric Ammonia Sodium Hydroxide Chromic Acid Hydroflouric Phosphorus Pentoxide Perchloric Acid Calcium Oxide Peroxides Nitrates/Nitrites
Observe the following special precautions: 1. Containers and equipment used for storage and processing of corrosive materials should be corrosion resistant. 2. Eye protection and rubber gloves should always be used when handling corrosive materials. A face shield, rubber apron, and rubber boots may also be appropriate, depending on the work performed. 3. When mixing concentrated acids (caustics) with water, add the acid (caustic) slowly to water. Never add water to acid (caustic). 4. Acids and bases should be stored separately from each other and flammables. Store all corrosives on a low shelf, near floor level but avoid storing them on the floor. Strong oxidizers such as perchloric acid present a fire and explosion hazard when in contact with organics. Store strong oxidizers in a glass container in a metal tray, away from organic, flammable, dehydrating or reducing agents. Do not use corks or rubber stoppers with strong oxidizing agents. 5. An emergency shower and eyewash station capable of drenching the body and eyes for 15 minutes must be within 10 seconds walking time from the work area or where corrosive materials are stored. (ANSIZ358.1-1990 Standard for Emergency Eyewash & Shower Equipment)

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Oxidizers: Oxidizers are materials which readily yield oxygen or another oxidizing gas, or that readily react to promote or initiate combustion of flammable/combustible materials. Oxidation reactions are a frequent cause of chemical accidents. Observe these precautions to reduce risk when storing or handling oxidizers. 1. Know the reactivity of the materials involved in experiment or process. Make sure that there are no extraneous materials in the area which could become involved in a reaction. 2. If the reaction can be violent or explosive, use shields or other methods for isolating the materials or the process. 3. Use the minimum amounts necessary for the procedure. Do not keep excessive amounts of the material in the vicinity of the process. 4. Store properly, away from organic materials, flammable materials and other reducing agents.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Water-Reactive Materials: Materials which react with water to produce a flammable or toxic gas, or other hazardous condition are said to be water-reactive. Fire and explosion are serious concerns when working with these materials. Special precautions for safe handling of water-reactive materials will depend on the specific material, and the conditions of use and storage. Contact EHS for information on the safe use of a specific material. Examples of water- reactives include alkali and alkaline earth metals (e.g. Li, Na, K, Ca, Mg), metal hydrides, some metal and nonmetal chlorides (e.g. SiCl4, PCl3, AlCl3), calcium carbide, acid halides and acid anhydrides.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Peroxidizables: Peroxidizables are substances or mixtures which react with oxygen to form peroxides. Some peroxides can explode with impact, heat, or friction such as that caused by removing a lid. Peroxides form inside the containers of some materials even if they have not been opened. Examples include ethyl ether, tetrahydrofuran, liquid paraffins (alkanes), and olefins (alkenes). See Appendix C for additional materials which may form peroxides. Precautions are given below.
1. Date all peroxidizables upon receipt and upon opening. Unless an inhibitor has been added by the manufacturer, materials should be properly disposed of after 18 months from date of receipt or 3 months from date of opening. 2. Do not open any container having obvious crystal formation around the lid. 3. Other special precautions are similar to those used for flammables.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Light-Sensitive Materials: Light-sensitive materials are unstable with respect to light energy. They tend to degrade in the presence of light, forming new compounds which can be hazardous, or resulting in conditions such as pressure build-up inside a container which may be hazardous. Observe the following precautions. 1. Store light-sensitive materials in a cool, dark place in amber colored bottles or other containers which reduce or eliminate penetration of light. 2. Date containers on receipt and upon opening, and dispose of surplus material after one year if unopened or 6 months if opened.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Shock-Sensitive or Explosive Materials: Shock-sensitive/explosive materials are substances or mixtures which can spontaneously release large amounts of energy under normal conditions, or when struck, vibrated, or otherwise agitated. Some materials become increasingly shock-sensitive with age and/or loss of moisture. The inadvertent formation of shock-sensitive/explosive materials such as peroxides, perchlorates, picrates and azides is of great concern in the laboratory. A list of some shock-sensitive materials appears in Appendix D. 1. Contact EHS by email or phone when work with shock-sensitive or explosive materials is planned or when it is suspected that the inadvertent formation of shock-sensitive materials in ductwork, piping, or chemicals being stored has occurred. 2. Date all containers of explosive or shock-sensitive materials upon receipt and when opened. Unless an inhibitor has been added, unopened shock-sensitive materials should be discarded within 12 months after receipt. Open containers of shock-sensitive materials should be discarded within 6 months of the date opened. 3. Use the minimum amount of materials necessary for a procedure. Keep a minimum amount of material on hand. 4. If there is a chance of explosion, use barriers or other methods for isolating the materials or the process.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Compressed Gases: Special systems are needed for handling materials under pressure. Toxic and corrosive gases present special problems in designing engineering controls. The physical and health hazards of any material are typically compounded by the pressure hazard. Carefully observe special precautions. 1. Always use the smallest size cylinder required to perform the work. 2. Cylinders of compressed gases must be handled as high energy sources. 3. Cylinders on wheeled carts must be capped and secured by an approved cylinder support strap or chain. The cart must be an approved cylinder cart. Do not attempt to take a loaded cylinder cart up or down a stairway. 4. All uncapped cylinders must be secured independently (not ganged behind a single chain) to a solid element of the lab structure. Carts are not acceptable for supporting uncapped or in-use cylinders. 5. Never bleed a cylinder completely empty. Leave a slight pressure to keep contaminants out. 6. Oil or grease on the high pressure side of an oxygen cylinder can cause an explosion. Do not lubricate an oxygen regulator or use a fuel gas regulator on an oxygen cylinder. 7. Always wear goggles or safety glasses with side shields when handling compressed gases. 8. Always use appropriate gauges, fittings, and materials compatible with the particular gas being handled. Regulators must be compatible with gas cylinders (do not use adapters). 9. When work with toxic, corrosive, or reactive gases is planned, plans should include information concerning specific handling requirements for the gas involved. Generally, these gases will need to be used and stored with local exhaust ventilation such as a lab hood or a gas cabinet designed for that purpose.

If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in some manner so as to comply.
Special Precautions for Working with Cryogens: Some of the hazards associated with cryogens (fluids used to maintain extremely low temperatures) are fire, pressure, embrittlement of materials, and skin or eye burns upon contact with the liquid. Cryogens can condense nearly pure liquid oxygen from the air, creating a severe fire risk. A pressure hazard exists because of the large expansion ratio from liquid to gas, causing pressure build up in containers. Many materials become brittle at extreme low temperatures. Brief contact with materials at extreme low temperatures can cause burns similar to thermal burns. Carefully observe all special precautions. 1. Equipment should be kept clean, especially when working with liquid or gaseous oxygen. 2. Mixtures of gases or fluids should be strictly controlled to prevent formation of flammable or explosive mixtures. 3. For flammable cryogens the precautions provided in the "Flammable/Combustible Materials" section of this booklet should be used. 4. Always wear goggles when handling cryogens. If there is a splash or spray hazard, a faceshield over the googles, an impervious apron or coat, cuffless trousers and fully covering non-lacing shoes should be worn. Watches, rings, and other jewelry should not be worn. Gloves should be impervious and sufficiently large to be readily thrown off should a cryogen be spilled. Cryo-gloves or pot holders should also be used. Respirators may be required if the cryogen is toxic and sufficient local exhaust ventilation is not available. 5. Containers and systems containing cryogens should have pressure relief mechanisms. 6. Containers and systems should be capable of withstanding extreme cold without becoming brittle. Glass containers should be taped solidly around the outside or encased in plastic mesh. 7. Funnels should not be used for pouring liquid nitrogen or any other cryogen. 8. Large mobile Dewars or LN2 refrigerators (or the trolleys carrying these) used for transporting cryogens within a building or between buildings should be equipped with a braking mechanism. 9. Large mobile Dewars at risk for tipping should be transported on appropriate carts. Wheeled trolleys may not be used if the vessel must pass over elevator thresholds or other slots/crevasses wider than 25% of the wheel width. 10. Dispensing stations designed to allow staff to fill smaller vessels from a larger self-pressurizing Dewar must be located in non-public areas, and should be posted with standard operating procedures. 11. Smaller vessels of liquid nitrogen or other cryogens transported by hand within or between buildings must have a handle or bail, and must be covered.
MSU Chemical Hygiene Plan Page 53
HEALTH HAZARDS "Health hazard" refers to chemicals for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. This term includes chemicals which are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, neurotoxins, agents which act on the hematopoietic system, and agents which damage the lungs, skin, eyes, or mucous membranes. For a detailed discussion of industrial toxicology and information on health hazards associated with specific chemicals, refer to Appendix E. For many toxic materials, hygienic standards have been established and action must be taken to prevent personnel from receiving exposures in excess of these standards. These standards may be referred to as threshold limit values (TLVs) or permissible exposure limits (PELs). For specific information on the terms TLV or PEL, refer to the glossary in Appendix I. The MSDS will list the hygienic standard for the hazardous chemical or each component of a mixture. In addition, EHS has a complete listing of published TLVs and PELs and other works concerning the subject of industrial toxicology. If you would like to conduct a more thorough review of a particular compound, or if you would like an evaluation of the exposure to a specific material used in your work area, contact EHS. Protection from health hazards is provided by ensuring that exposure to such hazards is minimized or eliminated. To minimize the exposure, it is necessary to determine the route by which the exposure may occur, i.e. inhalation, skin contact, puncture, ingestion, or a combination of exposure routes.

Special Precautions for Working with Allergens: The term allergens describes a wide variety of substances that can produce skin and lung hypersensitivity. Examples include diazomethane, chromium, nickel bichromates, formaldehyde, isocyanates, and certain phenols. Wear suitable gloves to prevent hand contact with allergens or substances of unknown allergenic activity. Conduct aerosol producing procedures in a fume hood.

Special Precautions for Working with Embryotoxins and Reproductive Toxins: Substances that act during pregnancy to cause adverse effects on the fetus are referred to as embryotoxins. These effects include embryolethality (death of the fertilized egg, the embryo, or the fetus), malformation (teratologic effects), retard growth, and postnatal functional deficits. Examples include organo-mercurials, lead compounds, and formamide. Because the period of greatest susceptibility to embryotoxins is the first 8-12 weeks of pregnancy, which includes a period when a woman may not know she is pregnant, women of child-bearing potential should take care to avoid skin contact with all chemicals. The term "reproductive toxins" is used to describe substances which cause harmful effects on the male or female reproductive system or the developing embryo and fetus. These effects include but are not limited to menstrual irregularity, lowered fertility, testicular atrophy, and birth defects. 1. Review each use of embryotoxins with the laboratory supervisor. 2. Label embryotoxins as follows: EMBRYOTOXIN: READ SPECIFIC PROCEDURES FOR USE. 3. Store embryotoxins and reproductive toxins in unbreakable containers or unbreakable secondary containers in a well ventilated area. 4. Guard against spills and splashes. Appropriate safety apparel, especially gloves, should be worn. All hoods, glove boxes, or other essential engineering controls should be known to be operating properly before work is started. 5. Notify your laboratory supervisor and EHS of all incidents of exposure or spills. EHS will arrange for a medical consultation.

Special Precautions for Working with Chemicals of Moderate Chronic or High Acute Toxicity: See Appendix E of this manual for definition and discussion of the meanings of chronic and acute toxicity. Examples of chemicals of moderate chronic toxicity or high acute toxicity include diisopropylfluorophosphate, hydrofluoric acid, and hydrogen cyanide.
1. Consult one of the standard compilations that list toxic properties of known substances and learn what is known about the substance that will be used. Follow the specific precautions and procedures for the chemical. 2. Use and store these substances only in designated (restricted access) areas placarded with appropriate warning signs. 3. Use a hood or other containment device for procedures which may result in the generation of aerosols or vapors; trap released vapors to prevent their discharge with fume hood exhaust. 4. Avoid skin contact by use of gloves and long sleeves and other protective apparel as appropriate. 5. Maintain records of the amounts of materials on hand, amounts used, and the names of the workers involved. 6. Be prepared for accidents and spills. At least two people should be present at all times if compounds in use are highly toxic or of unknown toxicity. 7. Store breakable containers in chemically resistant trays; also work and mount apparatus above such trays or cover work and storage surfaces with removable, absorbent, plastic backed paper. 8. If a major spill occurs outside the hood, evacuate the area and call for assistance (See cover page). 9. Thoroughly decontaminate or dispose of contaminated clothing or shoes. If possible, chemically decontaminate by chemical conversion to a less toxic product. 10. Store contaminated waste in closed, suitably labeled, impervious containers.

some manner so as to comply.
Special Precautions for Working with Chemicals of High Chronic Toxicity: See Appendix E of this manual for definition and discussion of the meanings of chronic and acute toxicity. Examples of chemicals exhibiting high chronic toxicity include dimethylmercury, nickel carbonyl, benzo-a-pyrene, N-nitrosodiethylamine, and other human carcinogens or substances with high carcinogenic potency in animals. 1. Conduct all transfers and work in designated (restricted access) areas: a restricted access hood, glove box, or portion of a lab, designated for use of highly toxic substances, for which all persons with access are aware of the substances being used and necessary precautions. 2. Protect vacuum pumps against contamination with scrubbers or HEPA filters and vent effluent into the hood. 3. Decontaminate vacuum pumps or other contaminated equipment, including glassware, before removing them from the designated area. Decontaminate the designated area before normal work is resumed there. 4. On leaving the area, remove protective apparel (placing it in an appropriate, labeled container) and thoroughly wash hands, forearms, face, and neck. 5. Use a wet mop or a vacuum cleaner equipped with a HEPA filter to decontaminate surfaces. DO NOT DRY SWEEP SPILLED POWDERS. 6. If using toxicologically significant quantities of a substance on a regular basis (in quantities above a few milligrams to a few grams, depending on the substance, 3 or more times per week), contact EHS. EHS will arrange for a medical consultation, if appropriate. 7. Keep accurate records of the amounts of these substances stored and used, the dates of use, and names of users. 8. The designated area must be conspicuously marked with warning and restricted access signs and all containers should be appropriately labeled with identity and warning labels (e.g., CANCER-SUSPECT AGENT). 9. Ensure that contingency plans, equipment, and materials to minimize exposures of people and property in case of accident are available. 10. For a negative pressure glove box, ventilation rate must be at least 2 volume changes/hour and at a pressure of at least 0.5 inches of water gauge. For a positive pressure glove box, thoroughly test for leaks before each use. In either case, trap the exit gases or filter them through a HEPA filter and then release them into a fume hood. 11. Use chemical decontamination whenever possible; ensure that containers of contaminated wasted are transferred from the designated area under the supervision of authorized personnel.

Special Precautions for Animal Work with Chemicals of High Chronic Toxicity:
Refer to Appendix E of this manual for definition and discussion of the meanings of chronic and acute toxicity.
Morehead State University's Institutional Animal Care and Use Committee (IACUC) is a federally-mandated committee made up of faculty, staff, and persons unaffiliated with the University charged with ensuring that the institution complies with federal policies safeguarding animals as subjects in research, testing, and teaching. All research, teaching and/or testing conducted at MSU involving animal subjects must be reviewed and approved by the IACUC. Please contact Shannon Harr, the Director, Research Integrity and Compliance, 606.783.2307 for more information.
The Guide for the Care and Use of Laboratory Animals can be found at this link. http://grants.nih.gov/grants/olaw/Guide-for-the-care-and-use-of-Laboratory-animals.pdf
1. For large scale studies, special facilities with restricted access are preferable. 2. When possible, administer the substance by injection or lavage instead of in diet. If administration is in the diet, use a caging system under negative pressure or under laminar air flow directed through HEPA filters prior to discharge. 3. Devise procedures which minimize formation and dispersal of contaminated aerosols, including those from food, urine, and feces (e.g., use HEPA filtered vacuum equipment for cleaning; moisten contaminated bedding before removal from the cage; mix diets in closed containers in a hood). 4. When working in the animal room, wear plastic or rubber gloves, fully buttoned laboratory coat or jumpsuit and, if needed because of incomplete suppression of aerosols, other apparel and equipment (shoe and head coverings, respirator). 5. Dispose of contaminated animal tissues and excreta using approved methods.
MODEL WRITTEN SOP -- The OSHA Laboratory Standard explicitly requires "standard operating procedures relevant to safety and health considerations to be followed when laboratory work involves the use of hazardous chemicals." If the model SOPs in this "Special Precautions" section do not fulfill this requirement, you must amend and append in
MSU Chemical Hygiene Plan Page 59
some manner so as to comply.
SPECIAL PRECAUTIONS FOR WORK WITH NANOPARTICLES AND NANOMATERIALS:
Nanoparticles and nanomaterials have different reactivities and interactions with biological systems than bulk materials, and understanding and exploiting these differences is an active area of research. However, these differences also mean that the risks and hazards associated with exposure to engineered nanomaterials are not well known. Because this is an area of ongoing research, consult trusted sources for the most up to date information available. Note that the higher reactivity of many nanoscale materials suggests that they should be treated as potential sources of ignition, accelerants, and fuel that could result in fire or explosion. Easily dispersed dry nanomaterials may pose the greatest health hazard because of the risk of inhalation. Operations involving these nanomaterials deserve more attention and more stringent controls than those where the nanomaterials are embedded in solid or suspended in liquid matrixes.
Consideration should be given to all possible routes of exposure to nanomaterials including inhalation, ingestion, injection, and dermal contact (including eye and mucous membranes). Avoid handling nanomaterials in the open air in a freeparticle state. Whenever possible, handle and store dispersible nanomaterials, whether suspended in liquids or in a dry particle form, in closed (tightly-sealed) containers. Unless cutting or grinding occurs, nanomaterials that are not in a free form (encapsulated in a solid or a nanocomposite) typically will not require engineering controls. If a synthesis is being performed to create nanomaterials, it is not enough to only consider the final material in the risk assessment, but consider the hazardous properties of the precursor materials as well.
To minimize laboratory personnel exposure, conduct any work that could generate engineered nanoparticles in an enclosure that operates at a negative pressure differential compared to the laboratory personnel breathing zone. Limited data exist regarding the efficacy of PPE and ventilation systems against exposure to nanoparticles. However, until further information is available, it is prudent to follow standard chemical hygiene practices. Conduct a hazard evaluation to determine PPE appropriate for the level of hazard according to the requirements set forth in OSHA’s Personal Protective Equipment standard (29 CFR 1910.132).
MSU Chemical Hygiene Plan Page 60
BIOLOGICAL HAZARDS Biohazards are a concern in laboratories in which microorganisms, or material contaminated with them, are handled. Anyone who is likely to come in contact with blood or potentially infectious materials at work is covered under OSHA's Bloodborne Pathogen Standard, 29 CFR § 1910.1030. Training in bloodborne pathogen control is required annually for employees with possible exposure and is provided by EHS online and in person. Contact EHS for initial training and the annual refresher. These hazards are usually present in clinical and infectious disease research laboratories but may also be present in any laboratory in which bodily fluids, tissues, or primary or immortalized cell lines of human or animal origin are handled. Biohazards are also present in any laboratory that uses microorganisms, including replication-deficient viral vectors, for protein expression or other in vitro applications. Occasionally, biohazards are present in testing and quality control laboratories, particularly those associated with water and sewage treatment plants and facilities involved in the production of biological products and disinfectants. *Policies and procedures pertaining to biological safety are contained in the "Morehead State University Biological Safety Manual." Contact EHS for a copy or locate it on the EHS website.
RADIOACTIVE MATERIAL HAZARDS Use of radioactive materials at Morehead State University is strictly controlled. The policies and procedures for handling radioactive materials are contained in the "Morehead State University Radiation Safety Manual." Contact the Radiation Safety Officer in the Office of Environmental Health and Safety 3-2179 if you are planning on using radioactive materials.
IONIZING AND NON-IONIZING RADIATION HAZARDS Use of ionizing and non-ionizing radiation at Morehead State University is overseen by the Radiation Safety Compliance Officer in the Office of Environmental Health & Safety. Please call 3-2179 for more information.
MSU Chemical Hygiene Plan Page 61
TRANSPORTATION OF HAZARDOUS MATERIALS
TRANSPORTATION OVER THE ROAD Any container of hazardous material transported on a road accessible to or used by the public is subject to the regulation by the U.S. Department of Transportation (DOT). DOT regulations require, in part, that no person may offer or accept a hazardous material for transportation unless the material is properly classified, described, packaged, marked, labeled, manifested, and in condition for shipment. This includes hazardous materials transported between the various University buildings and campuses. DOT regulations require the driver of a vehicle transporting hazardous materials in quantities requiring a placard to possess a Commercial Driver's License. For materials classified as "dangerous by inhalation", there is no exempt quantity. DOT regulations also specify training requirements for any individual who engages in the following activities: a. Load, unloads, or handles hazardous materials in transportation; b. Reconditions or tests containers, drums, or packages represented for use in the transportation of hazardous materials; c. Prepares hazardous materials for transportation; d. Is responsible for safety of transported hazardous materials; or e. Operates a vehicle (including personal vehicle) used to transport hazardous materials. Prior to shipping or transporting a hazardous material, contact the EHS at 3-2584 or Support Services. Refer to glossary for a complete definition of hazardous materials (see Hazardous Material DOT)
TRANSPORTATION INSIDE BUILDINGS AND BY FOOT 1. Approved Transport Container means a commercially available bottle carrier made of rubber, metal, or plastic with carrying handle(s) which is large enough to hold the contents of the container if broken in transit. Carrier lids or covers are recommended, but not required. Rubber or plastic should be used for acids/alkalies; and metal, rubber, or plastic for organic solvents. 2. Laboratory Carts used to transport chemicals from one area to another shall be stable and in good condition. Transport only a quantity which can be handled easily. Plan the route ahead of time so as to avoid all steps or stairs. 3. Freight Elevators, Not Passenger Elevators, should be used to transport hazardous chemicals whenever possible. The individual transporting the hazardous chemicals should operate the elevator alone if possible. Avoid getting on an elevator when a person is transporting hazardous chemicals.
WASTE DISPOSAL . You must refer to the “Waste Disposal Guidelines & Hazardous Waste Management Training Manual on the EHS website for the specific rules and regulations for all laboratory wastes.
MSU Chemical Hygiene Plan Page 62
CHEMICAL EMERGENCY SPILL PROCEDURES Plan in advance for an emergency. What are the possible emergencies which could occur during your work, e.g., fire, spill, high level chemical exposure? Are systems available to alert you to an emergency situation, e.g., chemical exposure monitoring systems? What supplies and equipment should you maintain in your area to assist you or emergency response personnel in the event of an emergency, e.g., eyewash and safety shower, spill control materials, personal protective clothing? What training do you need to handle an emergency in your area, e.g., emergency first aid or respirator use training? Is it safe for you to work alone?
BASIC STEPS FOR EMERGENCY RESPONSE Determine the nature of the emergency. • High hazard emergency. If the emergency is immediately dangerous to life and health, involves a large area, major injury to personnel, is a threat to personnel and the public, involves radioactive material, involves an infectious agent, or involves a highly toxic, corrosive, or reactive hazardous material, then proceed with Plan A below. • Low hazard emergency. If the emergency is small, there is no fire hazard, involves low to moderately toxic materials in small amounts, or involves a readily treatable injury, proceed with Plan B below. • Fire and fire-related emergencies. If the emergency involves a fire or fire-related situation such as abnormal heating of material, hazardous gas leaks, flammable liquid spill, smoke, or odor of burning, proceed with steps in the "FIRE AND FIRE-RELATED EMERGENCIES" section below. • If the emergency involves a mercury spill, see section headed "MERCURY SPILLS.” • Unknown. If you do not know the nature of the emergency or are in any way uncertain as to how to handle the emergency, proceed with Plan A below. Note: The Reportable Quantity (RQ) of a spilled hazardous material is one (1) pound for many chemicals. The university is legally required to report certain spills to the U.S. Environmental Protection Agency within twenty-four (24) hours of the spill. In order for the university to comply with this requirement, you must immediately report any spill of hazardous material over one (1) pound to EH&S. There can be legal consequences for a person who spills a Reportable Quantity of hazardous material and fails to report it. State 24-hour warning point for HAZMAT Spill Notification If you need to report a spill in accordance with SARA Title III Section 304 and KRS 39E.190, please contact the Duty Officer at the Commonwealth Emergency Operations Center at 800.255.2587 which serves as the twenty-four (24) hour warning point and contact for the Commonwealth Emergency Response Commission. Plan A: Immediately Dangerous to Life or Health If a chemical spill occurs that is determined to pose an immediate threat to any building occupant, proceed as follows:
• Isolate the area, if possible, and evacuate. • Keep others out of the area and take action to protect life and limb.
MSU Chemical Hygiene Plan Page 63
• Call emergency response numbers (see cover page) and activate the building fire Alarm system. When you call: 1. Identify yourself and the reason you are calling. 2. Identify the exact location of the emergency. 3. Identify the nature of the emergency, any injuries or symptoms involved, and any hazardous materials involved if you know them. 4. Provide rescue only if you are properly protected from the hazard. Never attempt to rescue someone who is unconscious unless you know what the problem is and • you know you are properly protected from the hazard. • Do not move a seriously injured person unless he/she is in further danger. • Anyone overcome with smoke or chemical gases or vapors should be removed to uncontaminated air and treated for shock. • Provide first aid if you have the capability & training. Ensure all those exposed seek proper medical treatment. Plan B: Not Immediately Dangerous to Life or Health • Follow the procedures listed below for spills involving chemicals that are definitively known to pose no immediate threat. • Evacuate the rooms and close the door, but do not lock it. • Immediately notify the building supervisor and the Office of Environmental Safety and Health. If ESH does not answer, or if your call is after normal business hours, contact MSU Police at 783-2035 to report the spill. Be prepared to give the following information: – Building name – Building location – Floor number – Room number – Type of spill – Chemical(s) involved – Estimated volume of chemical(s) involved • If trained and familiar with the hazards, attempt to contain the spill as much as possible. • Avoid direct physical contact with the spilled material. If contact is made, remove any contaminated clothing and flush area with water for 15 minutes. Use a safety shower, if one is available. • The Office of Environmental Safety and Health will notify the appropriate response agencies and assist in the spill cleanup.
FIRE AND FIRE-RELATED EMERGENCIES If you discover a fire or fire-related emergency such as abnormal heating of material, hazardous gas leaks, hazardous material or flammable liquid spill, smoke, or odor of burning, immediately follow these procedures:
MSU Chemical Hygiene Plan Page 64
• Activate the building fire alarm system (fire pull station). If not available or operational, verbally notify persons in the building. • Notify MSU Dispatch (see cover page). • Isolate the area and evacuate the building: ° Shut down equipment in the immediate area, if possible ° Close doors to isolate the area ° Use a portable fire extinguisher* to: • Assist oneself to evacuate • Assist another to evacuate • Control a small fire, if possible *Fire extinguisher training is required to use an extinguisher and is available from EHS. Staff that have not been trained to use extinguishers are not required to do so. • Provide the fire/police teams with the details of the problem upon their arrival. Special hazard information you may know is essential. If fire alarms are ringing in your building:
• evacuate the building • move at least 200 feet away from the building • stay clear of driveways, sidewalks and other access ways to the building • if you are a supervisor, try to account for your employees and report any missing persons to the emergency personnel at the scene. • Assist emergency personnel, as requested. • Do not reenter the building until directed to do so. Follow any special procedures established for your unit. For Lappin Hall, stay away from the second street side of the building and the brick pathway side between lappin and Combs.
MERCURY SPILLS For small spills, such as a thermometer break, use a trapped vacuum line attached to a tapered glass tube, similar to a medicine dropper, to pick up mercury droplets.
• Do not use a domestic or commercial vacuum cleaner. • Use a bright light. • Cover small droplets in accessible areas with one of the following: . sodium polysulfide solution . powdered sulfur . silver metal compounds . dry ice to freeze the mercury droplets • Scoop up residue with plastic scoop or wipe area with lightly dampened sponge. Place residue in container for hazardous waste collection and call EHS (3-2179). For larger spills, or any spill for which you believe unrecovered mercury might remain, contact EHS for spill clean-up, instructions, or assistance (3-2179).
MSU Chemical Hygiene Plan Page 65
INJURY AND ILLNESS Employees and students must notify their immediate supervisor or instructor of all illnesses and injuries related to exposure to hazardous chemicals. Employees and students should report to the Morehead Health Clinic in Allie Young if minor medical attention is required. Students should be accompanied by a friend, teaching assistant or instructor. If transportation is necessary, call 911 for an ambulance. Do not move a seriously injured person unless he/she is in further danger. Do not transport injured person(s) in personal or department vehicles. Call 911 for ambulance transportation.
In cases of serious injury or illness, it is imperative that appropriate actions be followed immediately. When in doubt as to what should be done, telephone the University Police for assistance. Give emergency and medical personnel the following information: • your name, location and nature of the emergency • the name of the chemical involved • the amount involved • area of the body affected • symptoms
The supervisor or instructor must ensure the appropriate injury report forms are completed. o Contact Risk Management & Human Resources for instructions. o If you have any questions regarding injury and illness procedures, contact your supervisor, instructor, or the University Police.
MINOR FIRST-AID
First Aid Kits. All laboratories should have access to a basic first aid kit. Department’s must maintain the first aid kit with essential supplies at all times. • First aid kits must be readily accessible. If the kit is not visible, the area where it is stored must be clearly marked. • Do not dispense or administer any medications, including aspirin. • Do not put any ointments or creams on wounds or burns. Use cool water. • The MSDS contains special first aid information. • Before giving first aid, call the University Police to transport the victim to a medical facility for evaluation. • Minor student and employee first aid cases are treated at the MSU Health Clinic. Visitor first aid cases are treated at the nearest off-campus hospital (St. Claire) • For specific first aid information, contact your supervisor, instructor, or the University Police.

Appendix C Peroxidizables
Peroxidizable chemicals such as those listed below should be dated upon receipt. Storage and use should be limited to the time indicated for each class or list. Containers which show signs of iron oxide or copper oxide should be handled with extra precaution since many metal oxides promote peroxide formation.
The most hazardous compounds – those which can accumulate a hazardous level of peroxides simply on storage after exposure to air – are in List A. Compounds forming peroxide that are hazardous only on concentration of impurities (as in distillation or evaporation) are in List B. List C consists of vinyl monomers that may form peroxides which can initiate explosive polymerization of the monomers.

Appendix E Industrial Toxicology Overview
Chemical Toxicology Toxicology is the study of nature and action of poisons.
Toxicity is the ability of a chemical molecule or compound to produce injury once it reaches a susceptible site in or on the body.
Toxicity hazard is the probability that injury will occur considering the manner in which the substance is used.
Dose-Response Relationships The potential toxicity (harmful action) inherent in a substance is manifest only when that substance comes in contact with a living biological system. A chemical normally thought of as “harmless” will evoke a toxic response if added to a biological system in sufficient amount. The toxic potency of a chemical is thus ultimately defined by the relationship that is produced in a biological system.
Routes of Entry into the Body There are four main routes by which hazardous chemicals enter the body: • Inhalation: Absorption through the respiratory tract. Most important in terms of severity. • Skin absorption. • Ingestion: Absorption through the digestive tract. Can occur through eating or smoking with contaminated hands or in contaminated work areas. • Injection: Can occur by accidental needle stick or puncture of skin with a sharp object.
Most exposure standards, Threshold Limit Values (TLVs) and Permissible Exposure Limits (PELs), are based on the inhalation route of exposure. They are normally expressed in terms of either parts per million (ppm) or milligrams per cubic meter (mg/m3 ) concentration in the air.
If a significant route of exposure for a substance is through skin contact, the TLV or PEL will have a “skin” notation. Examples are pesticides, carbon disulfide, carbon tetrachloride, dioxane, mercury, thallium compounds, xylene, hydrogen cyanide.
Types of Effects Acute poisoning is characterized by rapid absorption of the substance and the exposure is sudden and severe. Normally, a single large exposure is involved. Examples are carbon monoxide or cyanide poisoning.
Chronic poisoning is characterized by prolonged or repeated exposures of a duration measured in days, months or years. Symptoms may not be immediately apparent. Examples are lead or mercury poisoning, pesticide exposure.
MSU Chemical Hygiene Plan Page 73
Local refers to the site of action of an agent and means the action takes place at the point or area of contact. The site may be skin, mucous membranes, the respiratory tract, gastrointestinal system, eyes, etc. Absorption does not necessarily occur. Examples are strong acids or alkalis and war gases.
Systemic refers to a site of action other than the point of contact and presupposes absorption has taken place. For example, an inhaled material may act on the liver. Examples are arsenic affects the blood, nervous system, liver, kidneys and skin; benzene affects bone marrow.
Cumulative poisons are characterized by materials that tend to build up in the body as a result of numberous chronic exposures. The effects are not seen until a critical body burden is reached. Examples are heavy metals.
Substances in combination, meaning two or more hazardous materials present at the same time whose resulting effect is greater than the effect predicted based on the individual substances. This combined effect is called synergistic or potentiating effect. An example is exposure to alcohol and chlorinated solvents.
Other Factors Affecting Toxicity • Rate of entry and route of exposure; that is, how fast the toxic dose is delivered and by what means. • Age can affect the capacity to repair tissue damaged. • Previous exposure can lead to tolerance, increased sensitivity, or make no difference. • State of health, medications, physical condition, and life style can affect the toxic response. Pre-existing disease can result in increased sensitivity. • Environmental factors, such as temperature and pressure. • Host factors, including genetic predisposition and the sex of the exposed individual.
Physiological Classifications of Toxic Materials Irritants are materials that cause inflammation of mucous membranes with which they come in contact. Inflammation of tissue results from concentrations far below those needed to cause corrosion. Examples include: Ammonia Nitrogen dioxide Diethyl/dimethyl sulfate Hydrogen chloride Arsenic trichloride Hydrogen fluoride Halogens Phosphorus chlorides ozone Phosgene Alkaline dusts and mists
Irritants can also cause changes in the mechanics of respiration and lung function. Examples include: Sulfur dioxide Iodine Formic acid Formaldehyde Acetic acid Acrolein Sulfuric acid
MSU Chemical Hygiene Plan Page 74
Long term exposure to irritants can result in increased mucous secretions and chronic bronchitis.
A primary irritant exerts no systemic toxic action either because the products formed on the tissue of the respiratory tract are non-toxic or because the irritant action is far in excess of any systemic toxic action. Example: hydrogen chloride.
A secondary irritant's effect on mucous membranes is over-shadowed by a systemic effect resulting from absorption. Examples include hydrogen sulfide and aromatic hydrocarbons. Exposure to a secondary irritant can result in pulmonary edema, hemorrhage, and tissue necrosis.
Corrosives are chemicals which may cause visible destruction of or irreversible alterations in living tissue by chemical action at the site of contact. Examples include sulfuric acid, potassium hydroxide, chromic acid, and sodium hydroxide
Asphyxiants have the ability to deprive tissue of oxygen.
Simple asphyxiants are inert gases that displace oxygen. Examples include, nitrogen, nitrous oxide, carbon dioxide, hydrogen, and helium.
Chemical asphyxiants have as their specific toxic action rendering the body incapable of utilizing an adequate oxygen supply. They are toxic at very low concentrations (few ppm). Examples include carbon monoxide and hydrogen cyanide.
Primary anesthetics have a depressant effect upon the central nervous system, particularly the brain. Examples include halogenated hydrocarbons, ether, and alcohols.
Hepatotoxic agents cause damage to the liver. Examples include carbon tetrachloride, nitrosamines, and tetrachloroethane.
Nephrotoxic agents damage the kidneys. Examples include halogenated hydrocarbons and uranium compounds.
Neurotoxic agents damage the nervous system. The nervous system is especially sensitive to organometallic compounds and certain sulfide compounds. Examples include: trialkyl tin compounds insecticides thallium methyl mercury tetraethyl lead manganese organic phosphorus carbon disulfide
Some toxic agents act on the blood or hematopoietic system. The blood cells can be directly affected or bone marrow can be damaged. Examples include: nitrites benzene nitrobenzene
MSU Chemical Hygiene Plan Page 75
toluidine aniline
There are toxic agents that produce damage of the pulmonary tissue (lungs) but not by immediate irritant action. Fibrotic changes can be caused by free crystalline silica and asbestos. Other dusts can cause a restrictive disease called pneumoconiosis. Examples include coal dust, cotton dust and wood dusts.
A carcinogen commonly describes any agent or mixture which contains an agent that can initiate or speed the development of malignant or potentially malignant tumors or malignant neoplastic proliferation of cells. Known human carcinogens include: asbestos ethylene oxide coal tar pitch volatiles alpha-napthylamine N-nitrosodimethylamine 4-nitrobiphenyl 3,3'-dichlorobenzidine inorganic arsenic methyl chloromethyl ether vinyl chloride 1,2-dibromo-3- bis-chloromethyl ether chloropropane (DBCP)
A mutagen affects the chromosome chains of exposed cells. The effect is hereditary and becomes part of the genetic pool passed on to future generations.
A teratogen (embryotoxic or fetotoxic agent) is an agent which interferes with normal embryonic development without damage to the mother or lethal effect on the fetus. Effects are not hereditary. Examples include lead and dibromodichloropropane.
A sensitizer causes a substantial proportion of exposed people to develop an allergic reaction in normal tissue after repeated exposure to the chemical. The reaction may be as mild as a rash (contact dermatitis) or as serious as anaphylactic shock. Examples include: epoxides poison ivy chromium compounds formaldehyde amines toluene diisocyanate chlorinated hydrocarbons nickel compounds
Target Organ Effects
The following is a target organ categorization of effects which may occur, including examples of signs and symptoms and chemicals which have been found to cause such effects. • Hepatotoxics cause liver damage. Signs and symptoms: jaundice, liver enlargement Example chemicals: carbon tetrachloride, nitrosamines, chloroform, toluene, perchloroethylene, cresol, dimethylsulfate
• Nephrotoxics produce kidney damage. Signs and symptoms: edema, proteinuria

Appendix G Chemical Resistance Glove Guide
Choosing Chemical-Resistant Gloves Chemical-resistant gloves are an important piece of personal protective equipment when working with chemicals. A Material Safety Data Sheet (MSDS) is the first and usually the best place to find a recommendation for which glove is appropriate for the chemical you're using. The test data is generally from a laboratory environment and with one specific chemical. Glove manufacturers generally do not test chemical mixtures and don't consider other variables in your application, such as hot or cold temperatures and cut hazards. The following link provides chemical resistant glove information and charts.
Grainger: Choosing Chemical Resistant Gloves
On these chemical-resistance guide charts, you will find gloves made from many different materials. Different glove materials can react differently to individual chemicals. An important consideration when choosing a protective glove for working with chemicals is how the specific chemical reacts with the glove material. An MSDS that only specifies an acid-resistant glove is misleading because one glove material might work fine with hydrochloric acid, but provide little or no protection from nitric acid. Gloves are generally tested and rated in three categories for chemical compatibility: degradation, breakthrough time and permeation rate. All three should be considered when selecting a glove.
Degradation is a change in physical properties of the glove material. Common effects include swelling, wrinkling, stiffness, change in color or other physical deterioration. The degradation ratings indicate how well a glove will hold up when working with a specific chemical. Degradation tests vary by manufacturer. There is no standardized test that is used by everyone in the industry. However, the glove material usually has constant exposure to the test chemical and the percent weight change is then determined at time intervals.
Degradation is one critical factor when choosing a glove but other considerations are chemical breakthrough time and the permeation rate of the glove with the chemical. Degradation is usually the first test. Most manufacturers do not test permeation or breakthrough time if the chemical causes significant degradation to the glove material. Degradation alone can be enough to disqualify a glove for use with a chemical.
Breakthrough time is the elapsed time between initial contact of the chemical on one side of the glove material and the analytical detection of the chemical on the other side of the glove material. This test is conducted per ASTM F739 standard test method for resistance of protective clothing materials to permeation by hazardous liquid chemicals. The higher the result, the longer it takes for the chemical to pass through the glove material. The actual time reported on the chemical is usually listed on the compatibility charts. If breakthrough did not occur, the data reported is typically ND (none detected) or > (greater than) the indicated test
MSU Chemical Hygiene Plan Page 79 period. The times generally reflect how long a glove can be expected to provide resistance when totally submerged in the test chemical.
Permeation rate is a measurement that describes the rate of a chemical passing through the glove material at the molecular level. This process is similar to how a balloon loses air after enough time passes even though it is still tied and has no visible holes. The thickness of the glove can greatly affect the permeation rate. Manufacturers report permeation rate in different ways. Some report in micrograms of chemical per square centimeter of glove material per minute. The higher the result, the more of the chemical that passes through the glove material. Other manufacturers rate the permeation similar to that done for degradation: excellent (E), good (G), fair (F), poor (P) and not recommended (NR). If chemical breakthrough does not occur, permeation is not measured. This is reported as ND (none detected) or NT (not tested), depending upon the manufacturer. This test is also conducted per ASTM F739.
Sources The manufacturers' chemical-resistance glove links above will help you select the proper glove for handling hazardous chemicals. Choose the most appropriate glove by comparing the degradation, breakthrough time and permeation rates. Remember that these tests were conducted on specific gloves under laboratory conditions. Your application might also have temperature, cut resistance or other considerations. It is recommended that you consult your MSDS and conduct your own tests to determine the appropriate glove for your specific application.
Commonly Asked Questions Q. If a glove is compatible with 50% Nitric Acid, can I assume it will work for 10% Nitric Acid?
A. No. You should never assume that different concentrations will have the same effect on gloves as the test data. In fact, Nitric Acid is more corrosive at 10% than it is at 50%. You should always check the MSDS for chemical information and glove recommendations. It is also suggested that you perform your own tests before you use the glove in your application.

It is listed under the category, "known to be carcinogens," in the Annual Report on Carcinogens published by the National Toxicology Program (NTP) (latest edition); or 3. It is listed under Group 1 ("carcinogen to humans") by the International Agency for Research on Cancer Monographs (IARC)( latest editions); or 4. It is listed in either Group 2A or 2B by IARC or under the category, "reasonably anticipated to be carcinogens" by NTP. SENSITIZER - A substance that may cause no reaction in a person during initial exposures, but afterwards, further exposures will cause an allergic response to the substance.
SHORT-TERM EXPOSURE LIMIT - Represented as STEL or TLV-STEL, this is the maximum concentration to which workers can be exposed for a short period of time (15 minutes) for only four times throughout the day with at least one hour between exposures. Also the daily TLV- TWA must not be exceeded.
MSU Chemical Hygiene Plan Page 94
"SKIN" - This designation sometimes appears alongside a TLV or PEL. It refers to the possibility of absorption of the particular chemical through the skin and eyes; thus, a protection of large surface areas of skin should be considered to prevent skin absorption so that the TLV is not exceeded.
SPECIFIC CHEMICAL IDENTITY - The chemical name, Chemical Abstract Service (CAS) Registry Number, or any other information that reveals the precise chemical designation of the substance.
SOLVENT - A substance, commonly water, but in industry often an organic compound, which dissolves another substance.
STEL - Short-Term Exposure Limit
SUBSTANCE - A chemical element or compound; can also refer to a mixture.
SYNONYM - Another name by which the same chemical may be known.
SYSTEMIC - Spread throughout the body; affecting many or all body systems or organs; not localized in one spot or area. TERATOGEN - An agent or substance that may cause physical defects in the developing embryo or fetus when a pregnant female is exposed to that substance.
THRESHOLD LIMIT VALUE (TLV) - Airborne concentration of substances devised by the ACGIH that represents conditions under which it is believed that nearly all workers may be exposed day after day with no adverse effect. TLVs are advisory exposure guidelines, not legal standards, that are based on evidence from industrial experience, animal studies, or human studies when they exist. There are three different types of TLVs: Time-Weighted Average (TLV- TWA), Short-Term Exposure Limit (TLV-STEL), and Ceiling (TLV-C). (See also PEL).
TIME-WEIGHTED AVERAGE - The average time, over a given work period (e.g., 8-hour work day), of a person's exposure to a chemical or agent. The average is determined by sampling for the contaminant throughout the time period.
TLV - See Threshold Limit Value
TOXICITY - A relative property of a material to exert a poisonous effect on humans or animals and a description of the effect and the conditions or concentration under which the effect takes place.
TRADE NAME - The commercial name or trademark by which a chemical is known. One chemical may have a variety of trade names depending upon the manufacturers or distributors involved.
MSU Chemical Hygiene Plan Page 95
TRADE SECRET - Any confidential formula, pattern, device, information or compilation of information (including chemical name or other unique chemical identifier) that is used in an employer's business and that gives the employer an opportunity to obtain an advantage over competitors who do not know or use it.
TWA - See Time-Weighted Average
UEL - See Upper Explosive Limit
UFL - See Upper Explosive Limit
UNSTABLE (REACTIVE) - A chemical which, in the pure state or as a produced or transported, will vigorously polymerize, decompose, condense, or become self-reactive under conditions of shock, pressure, or temperature.
UPPER EXPLOSIVE LIMIT (Also known as upper flammable limit) - The highest concentration (expressed in percent of vapor or gas in the air by volume) of a substance that will burn or explode when an ignition source is present. Theoretically, above this limit the mixture is said to be too "rich" to support combustion. The difference between the LEL and the UEL constitutes the flammable range or explosive range of a substance. That is, if the LEL is 1 ppm and the UEL is 5 ppm, then the explosive range of the chemical is 1 ppm to 5 ppm. (Also see LEL)
USE - To package, handle, react, or transfer
VAPOR - The gaseous form of substances which are normally in the liquid or solid state (at normal room temperature and pressure). Vapors evaporate into the air from liquids such as solvents. Solvents with lower boiling points will evaporate faster.
WATER-REACTIVE - A chemical that reacts with water to release a gas that is either flammable or presents a health hazard.
WORK AREA - The department or office in which an employee may work. Facilities Maintenance, Department of Chemistry, the Office of the Registrar, and Environmental Health & Safety are examples of work areas.
WORK LOCATION - The site on campus and/or University property where the actual job occurs.
MSU Chemical Hygiene Plan Page 96
APPENDIX I
EPCRA Chemical Reporting
Extremely Hazardous Substances (EHSs)
The Consolidated List of Chemicals Subject to the Emergency Planning and Community Right-to-Know
Act (EPCRA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and Section 112(r) of the Clean Air Act (CAA) - also known as the List of Lists - was prepared to help firms handling chemicals determine, for a specific chemical, whether they may be subject to the following reporting requirements:
Emergency planning notification under EPCRA section 302 (40 CFR Part 355)
Emergency release notification under EPCRA section 304 (40 CFR Part 355)
Toxic chemical release reporting under EPCRA section 313 (40 CFR Part 372)
Hazardous substances release notification under CERCLA sections 102-103 (40 CFR Part 302) Accidental release prevention requirements under CAA 111(r) (40 CFR Part 68) http://www2.epa.gov/sites/production/files/2013-08/documents/list_of_lists.pdf
