"In November, 1985, the International Association of Fire Fighters (IAFF) requested assistance from the National Institute for Occupational Safety and Health (NIOSH) on behalf of their Local 1784 in Memphis, Tennessee to conduct a Health Hazard Evaluation (HHE) at the Memphis Fire Department (MFD). The request concerned the hearing levels and noise exposures of fire fighters who were assigned to two fire stations serving the Memphis International Airport. There was concern that these fire fighters were at a greater risk of accruing hearing loss because of the addition of aircraft noise to their occupational noise exposures. The city of Memphis and the MFD also requested NIOSH to investigate other fire stations in Memphis, not influenced by the airport, for noise exposures and hearing ability among more of the fire fighters."
