Health Hazard Evaluation Report HETA 81-459-1603; The City of New York Fire Department New York, New York [open pdf - 2MB]
"In August, 1981, the National Institute for Occupational Safety and Health (NIOSH) was requested by the Fire Department, City of New York (FDNY) to evaluate the noise levels found in the fire apparatus of the department. From November 9, through November 18, 1982, a noise survey was conducted on select fire apparatus during simulated response runs on the chauffeur's training road course at Randall's Island. Additionally, the noise levels found on shipboard were measured in one of the departments fire boats. [...] On the basis of the noise survey, it is concluded that the potential for noise over-exposure does exist for the FDNY's personnel. Because of this potential for excess noise exposure, NIOSH is restating its recommendations on bow to reduce noise in fire fighting operations which were first expressed in the Health Hazard Valuation Report to the Newburgh, New York Fire Department."
