A Health Hazard Evaluation (HHE) report by scientists of the US-American
National Institute for Occupational Safety and Health (NIOSH) concerns
potential exposure to noise by 911 dispatchers and mechanics in a fire station.
HHE Program investigators monitored noise exposure to mechanics and dispatchers
and looked at hearing test results. Investigators also interviewed workers and
looked at injury and illness records for trauma to the ears. The investigators
found that mechanics' exposure to noise was above the recommended exposure
limit, and that their exposures occurred over short periods of time.
Investigators also found that the potential for harm to 911 dispatchers'
hearing was low. Investigators recommended that managers enroll mechanics in a
hearing conservation program and require that mechanics wear ear plugs or ear
muffs when working with loud equipment. HHE Program investigators also
recommended that a communications center be built for 911 dispatchers or modify
the existing center to meet recommended indoor noise criteria for buildings.
