  • Chapter 9: Chemical Hazard Information
    CHEMICAL HAZARD INFORMATION CHAPTER 9 CONTENTS Overview ............................................................................................... 121 Reactive nature of chemicals ............................................................... 121 Organization of the chemical hazard information table ......................... 124 CHEMICAL HAZARD INFORMATION | Overview Many chemicals have minimal hazards, making them relatively safe to use. Others pose inherent risks and require specific precautions. Still, other chemicals must be handled with such extreme care that they are not practical or safe for school usage. This chapter provides a link to information on hazards for nearly 600 chemicals to help teachers, schools and divisions select and safely use chemicals. Schools and jurisdictions may use this information as a starting point for reviewing chemicals currently on its shelves (particularly where chemicals have accumulated over the years), and reassessing the scope and contents of chemical inventories. The information in this chapter includes numeric ratings for health, flammability and reactivity, plus supplementary comments on the scope and severity of hazards. It also includes WHMIS and storage classifications, as well as transportation hazard classes and disposal methods.This information has been compiled from the most reliable and accurate sources available at the time of writing. Inclusion of a chemical in the link listing does not signal appropriateness for school use, but is provided as preliminary information on potential concerns. Given the nature and severity of hazards involved, some of the chemicals listed are designated as not appropriate for use in schools due to safety considerations. Readers are advised to consult MSDS sheets and other current sources of more detailed information before using any of the chemicals listed in the link. Omission from this list is also not an indication of safety.

  • HAZARD COMMUNICATION COMPLIANCE CHECKLIST Item Y N
    HAZARD COMMUNICATION COMPLIANCE CHECKLIST Item Y N 1. Population Identification A criterion is established to determine employees that need Hazard Communication (HAZCOM) training? [The ANew Employee/Guest Orientation” form may be one method of compliance] 2. Training for identified populations a. Workers have received HAZCOM Standard Training (IND 200) [Retraining every two years is recommended. The audit criteria will be a current understanding of the Hazard Communication program and chemical safety by the employee.] b. Workers have received training on hazards specific to their area [May include “on-the- job” training, DACUMS, JTA, JSA, discussions with supervisor, tool box training, etc.] c. Workers are informed of safety requirements when new hazards are introduced into the workplace. 3. Hazard Information a. A copy of MSDSs for all chemicals used by the worker is kept in the location OR the BNL on- line MSDS system is used (http://www.esh.bnl.gov/cms/). b. Workers can demonstrate how to obtain a Material Safety Data Sheet (MSDS). c. MSDSs for chemicals, NOT acquired through Supply & Material Receiving are forwarded to the Safety & Health Services Division MSDS program (Building 129). d. Workers can demonstrate the ability to comprehend hazard information from MSDSs. e. Workers have a clear understanding of the hazards of the chemical they use (based on training and review of the MSDS). 4. Hazard Recognition and Control a. The supervisor (or cognizant individual) conducts a review prior to the use of chemicals to determine the appropriate protective measures. b. Workers follow appropriate protective measures established by their supervisor. 1. Hoods, vents or other engineering controls are used as necessary.

  • Contractor Safety Policies & Procedures
    NEW YORK MEDICAL COLLEGE CONTRACTOR SAFETY POLICIES AND PROCEDURES I. Introduction It is the expectation of New York Medical College (“NYMC”) that all work performed by contractors is provided in a safe, healthy and environmentally sound work environment for all who perform work on its premises.. The following policies and procedures are therefore critical in maintaining such an environment and must be followed by all contract personnel. A contractor's safety record at New York Medical College will be a criterion used to judge performance and determine whether or not a contractor qualifies for future contracts at NYMC. II. Contractor Health & Safety Responsibilities The contractor at all times maintains full responsibility and liability for safety and environmental compliance matters. Each contractor shall take prompt action on safety concerns as expressed by project management personnel or NYMC personnel. These safety policies and procedures are intended to assist contractors in reducing the possibility of accidents and establishing minimum standards to protect NYMC employees from construction activities. These safety policies and procedures are not intended to cover the full spectrum of published safety and health standards which are mandated by law, but rather to highlight specific NYMC and regulatory requirements that are most commonly of concern. Contractors shall not assume that they are responsible only for those safety practices which are referenced in these safety policies and procedures. In the event of a conflict between the provisions of these safety policies and procedures and applicable local, state or federal safety and health laws, regulations and/or standards, or the contract documents, the strict, conservative practices shall apply.

  • Hazard Communication (Right- To-Know)
    Right-to-Know The purpose of Vets First Choice Hazard Communication Program is to ensure VFC employees are effectively informed concerning workplace health and safety hazards, especially chemical hazards. The written Hazard Communication program addresses chemicals known to be present in the workplace to which employees may be exposed under normal conditions of use or in a foreseeable emergency. The Vets First Choice Hazard Communication Program extends to all VFC employees. Contacts Overall Program Management – o Jennifer O’Grady, Pharm D.

The objective of this law is to transmit information concerning the nature of chemical hazards that employees may be exposed to in their work environment and what measures they can take to protect themselves. A key component of compliance is employee training. Vets First Choice is responsible for making sure every employee receives appropriate training. To meet these training requirements, each employee is to read the booklet, “Hazard Communication –Right-to-Know”. Right-To-Know training sessions are held yearly for individuals requiring additional training on the use of chemicals and Material Safety Data Sheets (MSDSs).
