Which concept defines the order of hazard controls: elimination/substitution, engineering controls, administrative controls, and personal protective equipment?

Which concept defines the order of hazard controls: elimination/substitution, engineering controls, administrative controls, and personal protective equipment?

• A. Hierarchy of hazard controls
• B. Risk Reduction Model
• C. Safety Management Framework
• D. Job Hazard Analysis

Answer: (A)

The order in which hazard controls are applied is known as the hierarchy of hazard controls. It ranks methods from most to least effective at reducing risk: eliminate or substitute the hazard so it no longer exists or is less hazardous; implement engineering controls that physically remove exposure, such as guards or ventilation; use administrative controls that change how people work—like procedures, training, or scheduling—to reduce exposure; and rely on personal protective equipment as the last line of defense when some risk remains. This approach emphasizes removing the hazard at the source before depending on people or equipment to manage it. Other terms aren’t the standard way to express this ranking. A risk reduction model isn’t a widely used, defined hierarchy. A safety management framework is a broad organizational approach to safety, not the specific order of controls. A job hazard analysis helps identify hazards and can inform which controls to apply, but it doesn’t define the ordering of control methods itself.
