A plumber is using a power threading machine to prepare steel pipe. The machine is loud, and the plumber is wearing standard safety glasses but no hearing protection. What type of PPE is MOST critically missing for this task?
- AHearing protection
- BCut-resistant gloves
- CSteel-toe boots
- DHard hat
Show answer & explanationAnswer & explanation
Correct answer: A. Hearing protection
Power threading machines generate significant noise levels that can cause permanent hearing damage over time. Hearing protection (earplugs or earmuffs) is critically missing to protect against this specific hazard.
Why the other options are wrong
- B. Cut-resistant gloves are important for handling sharp pipes but not the most critical missing PPE directly related to the threading machine's operation noise.
- C. Steel-toe boots protect feet from falling objects, which is always good, but not the most critical missing PPE for the threading machine's noise.
- D. A hard hat is for overhead falling hazards, which is not the primary hazard described in this scenario.
Hearing Protection
Personal Protective Equipment (PPE) designed to reduce noise exposure to safe levels, preventing noise-induced hearing loss.
- Required for noise levels exceeding 85 dBA (8-hour TWA).
- Includes earplugs, earmuffs, or canal caps.
- Crucial for loud machinery operation.
Memory trick: Match the PPE to the hazard, protect yourself from harm's regard.
