You are planning PPE requirements for a job site. Workers will be exposed to impact hazards, chemical splashes, and noise levels of 92 dB. Calculate the minimum PPE cost per worker if safety glasses cost $15, chemical-resistant gloves cost $8, hard hats cost $25, and hearing protection costs $12.
Correct Answer
D) $60
All four types of PPE are required: safety glasses ($15) for impact, chemical-resistant gloves ($8) for splashes, hard hats ($25) for impact, and hearing protection ($12) for 92 dB noise exposure. Total: $15 + $8 + $25 + $12 = $60.
Why This Is the Correct Answer
The job site has multiple hazards requiring comprehensive PPE coverage. Impact hazards require both safety glasses ($15) and hard hats ($25) for eye and head protection. Chemical splashes necessitate chemical-resistant gloves ($8). The 92 dB noise level exceeds OSHA's 90 dB action level, requiring hearing protection ($12). All four PPE items are mandatory, totaling $60.
Why the Other Options Are Wrong
Option A: $48
Option D ($48) falls short by $12, suggesting the hearing protection requirement was overlooked. Since 92 dB exceeds OSHA's 85 dB action level, hearing protection is mandatory and must be included in the total PPE cost calculation.
Option B: $52
Option C ($45) significantly underestimates the required PPE cost by $15. This error likely stems from omitting the hard hat ($25) or failing to recognize that impact hazards require both eye and head protection in addition to chemical and hearing protection.
Memory Technique
Remember 'SIGHT-SOUND-SKULL-SKIN' - each hazard type needs specific protection, and noise above 90 dB always triggers hearing protection requirements in construction.
