| Abstract |
Three methods for assessing carbon monoxide (CO) exposures of wildland firefighters were tested and compared, and the activities and conditions under which this population may be exposed to hazardous CO levels were examined. Full-shift time-weighted average CO exposures, determined using passive diffusion monitors, were low for all employees monitored, with a mean of 8.2ppm (n=51). Real-time CO exposures for 12 individuals were monitored using electronic dataloggers. Two firefighters had one-minute exposures of, respectively, 339 and 212ppm, which exceeded the US Occupational Safety and Health Administration (OSHA) ceiling limit of 200ppm. Full-shift TWAs measured with the dataloggers agreed fairly well with those determined using the passive dosimeters. There was a small but statistically significant increase in CO in end-exhaled air across the shift (mean change was 2.2ppm). Change in CO concentration in end-exhaled air across the shift did not correlate well with average airborne exposure. |
