Health Hazard Evaluation Report HETA 82-319-1569; International Association of Firefighters, New Jersey [open pdf - 4MB]
"On June 25, 1982, The International Association of Firefighters (IAFF) requested that the National Institute for Occupational Safety and Health (NIOSH) evaluate the health hazards to emergency personnel potentially exposed to polychlorinated biphenyls (PCBs) and their combustion products while responding to a fire in a subway train operated by the Port Authority Trans-Hudson Corporation (PATH). NIOSH assigned the evaluation to the New Jersey State Department of Health, Occupational Health Program (OHP), under a Cooperative Agreement. [...] It was determined that the blood PCB levels of fire fighters increased slightly with age as well as with their length of service. It was impossible in this small, cross-sectional study to distinguish precisely the effects of age from the .effects of length of service. Recommendations on control methods including cleaning of contaminated equipment and clothing, and the installation of independent ventilation systems in subway tunnels are presented in the final section of this report."
