  • Controlling Hazards (PDF)
    Controlling Hazards Loss Control Bulletin Controlling Hazards Every workplace has the potential to expose an employee to occupational hazards which may result in injury or illness. Every employer has the responsibility of determining what hazards exist and how to properly control these hazards. One method that can be utilized to determine what hazards exist in an occupational setting is the job safety analysis. Once the hazards have been identified, a hierarchy of controls should be used to develop methods to protect employees from these occupa- tional hazards. Traditionally, a hierarchy of controls has been used as a means of determining how to implement feasible and effective controls for an occupational hazard. One representation of this hierarchy can be summarized as follows: Photo Credit: OSHA.gov The idea behind this hierarchy is that the control methods at the top of the list are potentially more effective and protective than those at the bottom. Applying this hierarchy is a systematic approach to identifying the most effective method of risk reduction. This normally leads to the implementation of inherently safer systems where the risk of illness or injury has been substantially reduced. Control Methods 1. Elimination and Substitution The first consideration for controlling hazards is to eliminate the hazard or substitute a less hazardous material or pro- cess. While eliminating or substituting is the most effective method to reduce hazards, it also tends to be the most diffi- cult to implement in an existing process as it may require major changes in equipment and procedures. One of the best times to utilize this method is during the design or development stage when making these changes can be inexpensive and simple to implement.

The Program establishes the responsibilities and procedures for preventing adverse health effects from occupational exposures, ensures compliance with laws and regulations mandating a safe and healthful working environment, and provides a comprehensive approach for prioritizing and managing occupational exposure risks. The systemic approach described in this Directive will allow designated staff to anticipate, recognize, evaluate, and control occupational exposure hazards present in VHA facilities. 3. RELATED ISSUES: VA Directive 7700 and VHA Directive 7701. 4. RESPONSIBLE OFFICE: The Director, Office of Occupational Safety Health and Green Environmental Management (GEMS) Programs (10NA8) is responsible for the contents of this Directive. Questions may be referred to 202-632-7889. 5. RESCISSIONS: None. 6. RECERTIFICATION: This VHA Directive is due to be recertified on or before the last working day of April 2021. David J. Shulkin, M.D. Under Secretary for Health DISTRIBUTION: Emailed to the VHA Publication Distribution List on 5/3/2016.

  • Equipment for COVID-19, Non-Essential Businesses
    Fact sheet Equipment for COVID-19, non-critical businesses Background Governor Tim Walz's Executive Order 20-33 requires each business in operation during the peacetime emergency establish a COVID-19 Preparedness Plan. This plan is designed to help a business keep their employees safe by taking steps to control exposure to COVID-19 by limiting contact, social distancing and assuring they have enough equipment prior to starting up, among other options. Communicating this plan and providing training to workers is key to implementing the plan. COVID-19 is spread mainly through close contact from person to person in respiratory droplets from someone who is infected. People who are infected often – but not always – have symptoms of illness. People without symptoms are able to spread the virus. COVID-19 is also spread from contact with a contaminated surface or object. Hierarchy of controls Occupational safety and health professionals use a framework called the “hierarchy of controls” to select ways of controlling workplace hazards. The best way to control a hazard is to remove it from the workplace, rather than relying on workers to reduce their exposure. During a COVID-19 outbreak, when it may not be possible to eliminate the hazard, the most effective protection measures are: 1. engineering controls; 2. administrative controls; 3. safe work practices (a type of administrative control); and 4. personal protective equipment (PPE). Types of controls In most cases, a combination of control measures will be necessary to protect workers. The following is a description of each control listed from most effective to least effective.

    MODULE 4 METHODS OF CONTROL Recognize Evaluate Control At the end of this module, you will be able to… Identify the three types of control that should be used to achieve electrical safety. Identify the engineering, administrative and PPE electrical controls you use on your job as well as the controls you should be using. Identify facts and procedures relating to lockout/tagout. List the steps required to achieve an electrically safe condition. Recognize when a work permit is required to work on energized electrical circuits. Recognize the appropriate warning signs to alert employees to the danger of electricity. Recognize the appropriate PPE to use based on the calculated energy value of an energy source. Given a case study, determine the most appropriate method of control and necessary corrective action. Prevention Strategies for Electrical Hazards 1 © 2008 National Safety Council MODULE 4 PARTICIPANT GUIDE Controls for Electrical Hazards Question: What is a control? Answer: Three Types of Control Engineering—Engineering controls engineer the hazard out by initial design specifications or by applying substituion methods, isolation, enclosure, or ventilation. Of the three types of controls, engineering control methods should be considered first. Examples: Administrative—Administrative controls reduce employee exposures through methods such as education and training, work reduction, job rotation, maintenance/repairs, housekeeping, personal hygiene, and appropriate work practices. Administrative controls depend on constant human implementation or intervention. Examples: Personal Protective Equipment (PPE)—Personal Protective Equipment is worn by employees to protect them from the environment. PPE includes anything from gloves to full body suits with self-contained breathing apparatus and can be used with engineering and administrative controls.
