The purpose of the Hierarchy of Controls is to do what?

• A. To describe hazard scouting technique
• B. To systematically control hazards by the most effective means
• C. To rate PPE sufficiency
• D. To categorize hazards by type

Answer: (B)

The main idea is to reduce risk by applying controls in order of their effectiveness. The point of the Hierarchy of Controls is to systematically control hazards by the most effective means, starting with eliminating the hazard or substituting a safer option, then using engineering controls to remove or isolate the hazard, followed by administrative controls to change how people work, and finally relying on personal protective equipment as a last line of defense. This emphasizes prevention at the source and design level rather than depending on workers to protect themselves with PPE, since PPE alone is less reliable and depends on proper use. For example, if a chemical hazard exists, you’d first look to remove or replace the chemical, then install ventilation or containment, then implement procedures or training, and only then use respirators if residual risk remains. The other ideas—hazard scouting, rating PPE sufficiency, or categorizing hazards by type—don’t describe the purpose of prioritizing controls to reduce exposure through the most effective means.
