Accepted Answer

Hard hat (safety helmet)

Answer

Hard hats are designed to absorb and deflect the impact of falling objects, protecting the skull and brain.

Question 4

Under the Hierarchy of Controls, what is the highest (most preferred) level of control for eliminating a hazard?

Accepted Answer

Elimination of the hazard

Answer

Elimination — physically removing the hazard — is the most effective control because it removes the risk entirely rather than managing it.

Question 5

A worker notices a gas leak smell near a trench. What is the CORRECT immediate response?
