Which hierarchy of controls is used to prioritize hazard mitigation?

The correct hierarchy of controls for prioritizing hazard mitigation is based on the effectiveness of each method in addressing hazards, starting from the most effective to the least effective. The sequence begins with elimination, which is the ideal scenario where the hazard is entirely removed, effectively preventing any risk of harm.

Following elimination, the next step is substitution. Substitution involves replacing a hazardous material or process with a less dangerous one, which also reduces risk but does not completely eliminate it like direct elimination would.

Engineering controls are then employed to isolate individuals from hazards through physical means, such as guards or ventilation systems. These controls can reduce or minimize exposure to the risk but still allow for the hazard to exist in some capacity.

Next on the list is administrative controls, which involve changing how people work. This includes policies or procedures such as training workers, scheduling shifts differently, or implementing safety protocols. Administrative controls can be effective but rely on human behavior, which can introduce variability in effectiveness.

Finally, personal protective equipment (PPE) is the last line of defense, which includes gear like gloves, helmets, and goggles that individuals wear to protect themselves from hazards. While PPE can be critical for safety, it does not eliminate the hazard itself and relies heavily on proper use and compliance
