The National Institute for Occupational Safety and Health (NIOSH) is the federal agency responsible for conducting scientific research for the prevention of work-related illness, injury, disability and death, and for making recommendations for improving safety and health in the workplace.

Due to reports of “higher than normal” rates of cancer found among firefighters, NIOSH, with support from the United States Fire Administration, has embarked on expanded research to clarify the relationship between work-related exposures and incidents of cancer.
