Hierarchy of Controls” Specifies the Order in Which Controls Are Implemented in the Workplace
Hierarchy of FactSheet Controls he “Hierarchy of Controls” specifies the order in which controls are implemented in the workplace. They are the means for reducing employee exposures to occupational hazards. Control measures are established to T maintain employee exposures below permissible and recommended limits. It is usually more cost-effective to implement safety • Personal Protective Equipment – PPE (e.g., measures before facilities or processes are built. By using respirators, fall protection, ear plugs, lab coat) is used this proactive approach, controls are implemented in the when engineering controls are not available and/or to early stages of a project, resulting in the prevention of enhance existing engineering controls. injuries, environmental incidents, and property damage. What I need to do... • Elimination – Remove the hazard from the workplace. It is the most effective way to control a risk because • Employ engineering controls routinely such the hazard is no longer present. as a chemical fume hood, biosafety cabinet, • Substitution – Use a chemical that is less hazardous machine guarding, and guard rails to isolate or less toxic than a principal ingredient in a synthesis, the hazards. for instance. This may add more steps to the process, • Read and comprehend administrative but may be safer in the long run. Conduct a hazard controls such as protocols, standard operating assessment to verify. procedures, and warning signs. Complete • Engineering Controls – Enclose or isolate the hazard safety training to understand occupational with local exhaust ventilation, machine guarding, hazards and risks. guardrails, or other safety equipment. • Wear the appropriate personal protective • Administrative Controls – Require workers to do equipment for the hazard.
