Health Hazard Evaluation Report HETA 83-360-1495; Chester Fire Department Chester, Pennsylvania [open pdf - 3MB]
"On July 20, 1983, the National Institute for Occupational Safety and Health (NIOSH) was requested by the International Association of Fire Fighters to evaluate possible long-term health effects in fire fighters in Chester, Pennsylvania, who in 1978 fought a fire at a chemical waste dump. Several of the fire fighters had subsequently developed malignancies. Previous evaluation by the Environmental Protection Agency showed that 32 carcinogens or toxins and five heavy metals were detectable at the dump site. [...] There is a statistically significant excess incidence of all cancers combined among fire fighters and other personnel who extinguished the ABM-Wade fire. The precise explanation for this excess is unclear. It is not likely that the excess is related to that fire even though these workers were exposed to numerous carcinogens and their thermal decomposition products. Whether they may in the future be at an additional risk of cancer cannot be determined."
