Evaluation of potential noise hazards to mechanics and 911 dispatchers at a fire department.
Int J Occup Environ Health 2009 Jan; 15(1):111-112
The HHE Program responded to a management request at a fire department. The request concerned potential exposure to noise among 911 dispatchers and mechanics in the fire station. HHE Program investigators monitored mechanics' and dispatchers' noise exposures 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 NIOSH 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 that the existing center be modified to meet recommended indoor noise criteria for buildings.
