  1. At what 8-hour TWA noise exposure level must an employer implement a hearing conservation program under OSHA?

    Answer: 85 dBA

    OSHA requires a hearing conservation program for all employees exposed to an 8-hour TWA of 85 dBA or above, known as the action level.

  2. What exchange rate does OSHA use for calculating noise dose?

    Answer: 5 dB doubling rate

    OSHA uses a 5 dB exchange rate, meaning that for every 5 dB increase, the allowable exposure time is halved.

  3. Which OSHA standard specifically addresses occupational noise exposure in general industry?

    Answer: 29 CFR 1910.95

    29 CFR 1910.95 is the OSHA standard governing occupational noise exposure and hearing conservation programs in general industry.

  4. Under OSHA, how must hearing loss be recorded on the OSHA 300 Log?

    Answer: When an STS is confirmed and the average hearing level at 2000, 3000, and 4000 Hz reaches 25 dB or more

    OSHA recording criteria require both a confirmed STS AND an average hearing level of 25 dB HL or more at 2000, 3000, and 4000 Hz.

  5. What is the maximum permissible exposure limit for noise under OSHA for an 8-hour workday?

    Answer: 90 dBA TWA

    The OSHA PEL for noise is 90 dBA as an 8-hour time-weighted average.

  6. Which federal agency publishes recommended exposure limits for noise that differ from OSHA PEL?

    Answer: NIOSH

    NIOSH recommends an REL of 85 dBA TWA using a 3 dB exchange rate, which is more protective than OSHA.
