The Hierarchy of Controls is a safety system used to reduce or eliminate hazards at work. 4)Administrative Controls - Change work practices
How it reduces risk: Reduces how long or how often workers are exposed. It ranks safety measures from most effective to least effective
1)Elimination - Remove the hazard completely
How it reduces risk: No hazard = no exposure. 3)Engineering Controls - Physically isolate people from the hazard
How it reduces risk: Workers can't come into contact with the hazard even though it's still present.
