It often involves doing a risk assessment to evaluate and prioritize the hazards and risks. In most cases, elimination is not feasible and when possible, substitution is the best approach to hazard mitigation. • Did the establishment validate the control methods, including preventive measures and prerequisite programs, for this hazard? Have workers been adequately informed about the situation? Evaluating and selecting temporary and permanent controls. It must also provide them with information on how to protect themselves and co-workers. Because contaminants are exhausted to the outdoors, you should also check with your local environment ministry or municipality for any environmental air regulations or bylaws that may apply in your area. A strong safety culture is at the heart of any safety-conscious … Monitoring should be done before and as well as after the change is implemented to make sure the changes did, in fact, control the hazard. Spot the hazard. • Can the establishment support that the hazard is not reasonably likely to occur (NRLTO)? The goal, obviously, is to choose a new chemical that is less hazardous than the original. Overview Think of a control measure as an action aimed to eliminate a hazard completely. Hierarchy of hazard control is a system used in industry to minimize or eliminate exposure to hazards. It is sometimes grouped with elimination because, in effect, you are removing the first substance or hazard from the workplace. An enclosure keeps a selected hazard "physically" away from the worker. Use mechanical transportation rather than manual methods. Training must cover not only how to do the job safely but it must also ensure that workers understand the hazards and risks of their job. For more information about PPE programs, please see the following document Designing an Effective PPE Program. For example, in the case of a noise hazard, temporary measures might require workers to use hearing protection. An effective plan will address serious hazards first. degreasing operations) to reduce solvent surface area and to lower solvent loss. See the OSH Answers document Substitution of Chemicals: Considerations for Selection for more information. A hazard control plan describes how the selected controls will be implemented. Some hazards and their controls will be specifically outlined in legislation. This is the Safety and Health website of the United Food and Commercial Workers International Union. Reduce vapour concentrations by … Use wet methods rather than dry when drilling or grinding. Examples include substituting toluene for benzene, non-lead-based paints for lead-based ones, or SawStop table sawsfor existing traditional table saws. The hazard controls in the hierarchy are, in order of decreasing effectiveness: Elimination Substitution Engineering controls Administrative Local exhaust ventilation is very adaptable to almost all chemicals and operations. These controls, however, are always going to be necessary in the meatpacking, poultry and food processing industries. PPE, work practice controls, and administrative controls are considered the least effective hazard controls. Replace gasoline motors wi… ... Equipment and method… indirectly from any use or reliance upon the information. A fan which draws the air from the hood into the ducts and removes the air from the workspace. These methods don’t get rid of the hazard. Contact our Safety InfoLine Another type of substitution includes using the same chemical but to use it in a different form. Some tools include physical inspection, testing, exposure assessment, observations, injury and illness tracking, accident/incident investigations reports, employee feedback/input, occupational health assessment and other methods. Example: John and Morris run the risk of falling while repairing an overhead light. Scheduling maintenance and other high exposure operations for times when few workers are present (such as evenings, weekends). Examples of these hazard controls include warning systems, visual or audible alarms, warning signs, or other indicators that alert the worker to a situation. Use electric motors rather than diesel ones to eliminate diesel exhaust emissions. Please see the OSH Answers document on emergency planning for more information. Check out our What’s New listing to see what has been added or revised. Lukman Nulhakiem is a production engineer who works for a hydrogen peroxide plant … The best way to protect workers is to remove or eliminate the hazard from the workplace using the following hazard control methods: Substitution. During the ev… Some sources may use a variation of this hierarchy. Remember, however, that you need to make sure the substitute chemical or substance is not causing any harmful effects, and to control and monitor exposures to make sure that the replacement chemical or substance is below occupational exposure limits. For example, a dry, dusty powder may be a significant inhalation hazard but if this material can be purchased and used as pellets or crystals, there may be less dust in the air and therefore less exposure. In addition, both "normal" and any potential or unusual situations must be studied. This also applies to conditions and activities. Contact us to let us know. Before deciding to replace a chemical/substance with another, consider all the implications and potential risks of the new material. Various illustrations are used to depict this system, most commonly a triangle.
