In hazard control, which option best describes eliminating exposure by removing the hazard from the environment?

• A. Provide training
• B. Remove the hazard entirely
• C. Implement PPE
• D. Substitute with a less hazardous material

Answer: (B)

Eliminating exposure by removing the hazard from the environment stops risk at its source. When the hazard is gone, there’s nothing left to expose workers to, so exposure cannot occur. This is the strongest form of hazard control and sits at the top of the hierarchy of controls because it eliminates the possibility of harm rather than just reducing it or protecting against it.

Training helps people work safely, but it doesn’t remove the hazard itself, so exposure can still happen if unsafe practices slip. Personal protective equipment provides a barrier, yet the hazard remains in the environment and a failure or breach can still lead to exposure. Substituting with a less hazardous material reduces risk, but it doesn’t completely remove exposure if the substitute still poses some danger. By removing the hazard entirely, you achieve the most robust protection since exposure is no longer possible.
