THE OSHA VS. ACGIH VS. NIOSH VS. DOD NOISE DOSIMETRY REQUIREMENTS AND WHICH SHOULD AN EMPLOYER FOLLOW

 THE OSHA VS. ACGIH VS. NIOSH VS. DOD NOISE DOSIMETRY REQUIREMENTS AND WHICH SHOULD AN EMPLOYER FOLLOW?

OSHA (Occupational Safety and Health Administration), ACGIH (American Conference of Governmental Industrial Hygienists), NIOSH (National Institute for Occupational Safety and Health), and DOD (Department of Defense) all have guidelines for noise exposure and dosimetry in the workplace. Their requirements differ in some respects, but they all aim to protect workers from noise-induced hearing loss.

OSHA requires employers to implement a hearing conservation program when noise exposure levels equal or exceed an 8-hour time-weighted average (TWA) of 85 decibels (dB) measured using a sound level meter. OSHA also requires employers to provide hearing protection to employees if noise exposure levels exceed 90 dB TWA. OSHA specifies the use of dosimeters, which are personal noise dosimeters that measure and record an employee's noise exposure throughout the work shift.

ACGIH recommends a more conservative exposure limit of 85 dB TWA, as well as a lower action level of 80 dB TWA. ACGIH also recommends using dosimeters to measure employee noise exposure, but with different requirements for how often measurements should be taken.

NIOSH recommends a lower exposure limit of 85 dB TWA, as well as a lower limit of 80 dB TWA for impulse noise. NIOSH also recommends the use of dosimeters to measure noise exposure, with specific requirements for calibration and use.

DOD has specific guidelines for noise exposure and dosimetry, which include exposure limits that vary depending on the duration of exposure and the type of noise. DOD also requires the use of noise dosimeters to measure and record employee noise exposure.

In terms of which requirements an employer should follow, it depends on the specific workplace and the applicable regulations. Employers should comply with all applicable regulations and guidelines, including OSHA, ACGIH, NIOSH, and DOD requirements. Employers may also choose to follow the most conservative guidelines for additional protection.
