Which statement correctly describes the exposure criteria for Steady State Noise?

• A. 8-hr TWA above 85 dB requires enrollment in Hearing Conservation Program.
• B. Steady State Noise: above 85 dB requires hearing protection and an 8-hr TWA above 85 requires enrollment in HCP.
• C. Steady State Noise: above 95 dB requires hearing protection only
• D. Steady State Noise: above 75 dB requires training

Answer: (B)

The key idea is the OSHA action level for steady-state noise, which is 85 dB over an 8-hour TWA. When noise is steady and above this level, workers must have hearing protection available and use it to control exposure. If a worker’s 8-hour TWA exceeds 85 dB, the employer must enroll that worker in a Hearing Conservation Program, which brings in annual audiometric testing, training, and proper recordkeeping. The correct statement captures both parts: above 85 dB requires hearing protection, and an 8-hour TWA above 85 requires enrollment in the Hearing Conservation Program. The other options miss one or both requirements or rely on thresholds that aren’t the established action level.
