Chemical hazards of a fire-fighting training environment.

Chemicals occurring in the vapor phasic and on airborne soot from a diesel oil fire in a firefighting training structure were analyzed by mass spectroscopy and gas chromatography. Forty-five compounds from a grab sample of the atmosphere and seventeen aromatic structures from deposited soot wore identified. Known carcinogens were found on the soot, and benzo(a)pyrene was quantitated fluorimetrically. The results suggest that a potential health hazard exists here.
