Exposure of firefighters to toxic air contaminants.
A personal sampling apparatus for firefighters was developed to sample the fire atmosphere for CO, CO2, O2, NO2, HCI, HCN and pariculate content. Two fire companies made ninety successful sample runs during structural fires. CO presented a potential acute hazard and particulate concentrations were high. HCN was detected at low levels in half the samples. HCI was detected in only eight samples but on two occasions exceeded 100 ppm. CO2 and NO2 levels and O2 depression do not appear to represent significant hazards.
