Fire fighter noise exposure.

U Reischl, H S Bair, P Reischl

    American Industrial Hygiene Association Journal
    |June 1, 1979

    Summary
    This summary is machine-generated.

    Firefighters face dangerous noise levels during emergency responses, with sound pressure exceeding 115 dBA. A hearing conservation program is crucial to protect their hearing from excessive occupational noise exposure.

    Area of Science:

    • Occupational health
    • Audiology
    • Emergency medical services

    Background:

    • Firefighters are exposed to high noise levels during emergency responses.
    • Previous studies have not fully characterized noise exposure across various firefighter roles and vehicle types.

    Purpose of the Study:

    • To evaluate occupational noise exposure for firefighters in different positions and on various emergency vehicles.
    • To compare noise levels against established occupational safety limits.
    • To assess the hearing health of firefighters through audiogram analysis.

    Main Methods:

    • Monitoring sound pressure levels during 170 Code-3 responses across three emergency vehicle types.
    • Performing octave band analyses for overall and specific noise sources.

  • Evaluating 89 firefighter audiograms.

    • Main Results:

    • Sound pressure levels frequently exceeded 115 dBA during Code-3 responses.
    • Noise exposures often surpassed the Occupational Safety and Health Administration (OSHA) allowable limit of 90 dBA for eight-hour exposure.
    • Audiometric evaluation indicated potential hearing issues among firefighters.

    Conclusions:

    • Firefighters experience excessive, short-duration, high-intensity noise exposure under current operational conditions.
    • A comprehensive hearing conservation program is recommended for the fire service to mitigate noise-related risks.
