Twenty-two workers are exposed to high-noise chipping, and hearing protection is issued to 16. How many more workers need protection?
Correct Answer
C) 6 workers.
The additional workers are 22 - 16 = 6.
Why This Is the Correct Answer
The additional workers are 22 - 16 = 6.
Why the Other Options Are Wrong
Option A: 4 workers.
4 workers. is below the supported result for hearing ppe; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 16 workers.
16 workers. is above the supported result for hearing ppe; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 22 workers.
22 workers. is above the supported result for hearing ppe; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Measure to additional, adjust for controlling, then let Checking Protection set the finish line.
Reference Hint
Study anchor (closed-book): memorize Hearing PPE from Cal/OSHA Title 8; CSLB Law and Business Study Guide / Title 8 occupational noise and hearing protection requirements; know the rule or calculation trigger without relying on exam-room lookup.
