OSHA 10-Hour Construction ReviewHealth Hazards in ConstructionMedium
A construction worker is exposed to noise levels consistently above OSHA's Action Level of 85 dBA TWA, but below the Permissible Exposure Limit (PEL) of 90 dBA TWA. What is the employer's primary responsibility under the Hearing Conservation Program in this situation?
- AImplement engineering controls to reduce noise below 85 dBA.
- BOffer annual audiometric testing to affected employees.
- CConduct continuous noise monitoring for all shifts.
- DProvide hearing protection and ensure its use.
Show answer & explanationAnswer & explanation
Correct answer: B. Offer annual audiometric testing to affected employees.
When noise exposure meets or exceeds the Action Level (85 dBA TWA), employers must implement a Hearing Conservation Program, which includes offering annual audiometric testing to monitor employees' hearing acuity.
Why the other options are wrong
- A. Engineering controls are preferred, but not immediately mandatory solely for exceeding the Action Level; they become mandatory if PEL is exceeded.
- C. Continuous noise monitoring is not a primary ongoing requirement for all shifts once initial monitoring has established exposure levels.
- D. Hearing protection must be made available, but its use is generally voluntary between 85-90 dBA TWA unless a standard threshold shift (STS) occurs.
Hearing Conservation Program (Action Level)
When noise exposure reaches or exceeds OSHA's Action Level of 85 dBA TWA, employers must implement a Hearing Conservation Program, which mandates annual audiometric testing for affected employees.
- Action Level = 85 dBA TWA.
- Triggers Hearing Conservation Program.
- Mandates audiometric testing, training, and making hearing protectors available.
Memory trick: 85 dBA: Action Level means Audiometric time!
