SECTION 1: WORKPLACE SAFETY - Questions 1-15
Q1: PPE for Hearing Protection
The student is reviewing workplace safety. Which type of PPE is designed to protect against hearing
damage from loud machinery?
A. Safety glasses
B. Earplugs or earmuffs
C. Hard hat
D. Respirator
Correct Answer: B
Rationale: Earplugs and earmuffs reduce noise exposure and prevent hearing loss. Safety glasses
protect eyes, hard hats protect the head, and respirators protect against airborne contaminants.
[100% CORRECT]
