Two surveys were carried out for 632 fire fighters 6 to 10 years following a baseline examination to determine any change in their pulmonary function. The longitudinal study evaluated the rate of change in forced expiratory volume in 1 second (FEV1) from the first to the second survey and on the relationship between the observed change and fire fighting exposures. Men who never wore a mask while extinguishing fires experienced a 1.7 times greater rate of FEV1 decline than those who did wear masks. Men with ammonia (7664417) exposure experienced a rate of decline 1.7 times greater than nonexposed men. Neither length of time spent in exposed jobs nor number of responses was associated with the rate of decline. Active fire fighters experienced a rate of decline 2.5 times greater than those who had retired or resigned. Some effects differed between men who were able to perform repeatable pulmonary function tests and those who were not.
