CSLB C-36 Plumbing ContractorSafetyEasy
A plumbing contractor is using a portable grinder to cut metal pipe sections. Which of the following is the most critical personal protective equipment (PPE) item to wear to prevent eye injuries from sparks and flying debris?
- ASafety glasses with side shields
- BWelding helmet
- CImpact-resistant goggles
- DFace shield over safety glasses
Show answer & explanationAnswer & explanation
Correct answer: D. Face shield over safety glasses
While safety glasses provide primary protection, a face shield worn over safety glasses offers comprehensive protection against high-velocity sparks, metal fragments, and grinding debris, which is essential when using a grinder.
Why the other options are wrong
- A. Safety glasses offer primary protection but may not fully protect against high-velocity sparks and larger debris generated by a grinder.
- B. A welding helmet is primarily designed for intense UV/IR radiation and high heat from welding, not typically for the impact protection needed for grinding.
- C. Impact-resistant goggles offer good protection but a face shield provides broader coverage for the entire face, which is beneficial when grinding.
Grinding Eye Protection
When grinding, eye protection must guard against high-velocity sparks, metal fragments, and abrasive debris.
- Always use primary eye protection (safety glasses).
- Secondary protection (face shield) is often required.
- Ensure both are impact-rated.
Memory trick: Grind with a guard, eyes and face safely scarred (not!).
