In the hierarchy of controls, which option is the most effective for eliminating hazards?

• A. Elimination
• B. PPE
• C. Administrative controls
• D. Substitution

Answer: (A)

Elimination removes the hazard from the workplace entirely, so the exposure path no longer exists. When the hazard is eliminated, workers aren’t exposed at all, making it the most reliable and robust form of protection because it prevents harm at the source rather than relying on protection or changes in behavior downstream. Substitution also reduces risk by replacing the hazard with something less dangerous, but it doesn’t remove the hazard completely and can introduce other risks. PPE provides a barrier between the worker and the hazard, yet it depends on proper use and does not eliminate the hazard itself. Administrative controls and other non-elimination strategies reduce exposure but do not remove the hazard, and they can be less foolproof due to variable compliance and implementation.
