Workers working in car painting workshops are exposed to different contaminants including isocyanates. One of the most important sequelae of this exposure is occupational asthma. The aim of this study was to identify alterations in peak expiratory flow test in the workers working in the car painting workshops. This was a cross-sectional descriptive study. 43 workers were selected randomly from the car painting workplaces in Isfahan. The peak expiratory flow of the workers was measured by means of a peak flow meter set at the beginning and at the end of the work shift, for one week. The mean percentage of alterations in peak expiratory flow was 6.91% on the first day and 8.11% on the last day of week. The mean percentage of alternation of peak expiratory flow of the workers were 11.2±1.8 and 7.9±1.9 an the day of exposure to the contaminants after painting, and also one day after exposure respectively, which was indicative of pathological changes in the lungs of the workers, as shown by standard tests of pulmonary function. 72% of the workers after exposure to the contaminants showed alternation of more than 10% in the peak expiratory flow. This study showed there is high risk of occupational asthma and other lung diseases in the workers working in car painting workshops and peak flow meter test can be useful for assessment of pulmonary disorders

Abstract Hexamethylene diisocyanate is an aliphatic isocyanate and car painters are exposed to it. One of the most important disorders is occupational asthma. The aim of this study was to survey the effect of 1, 6 hexamethylene diisocyanate on the peak expiratory flow test to car painters in Isfahan. In this descriptive and a cross-sectional study the forty three car painters were included. The sample were extracted and analyzed with high performance liquid chromatography. Peak expiratory flow test was carried out within a period of one week of working shift. The averages of daily and weekly exposure of workers to Hexamethylene diisocyanate concentration were. 0.42±0.1 and 0.13±0.05mg/m3, respectively The average of variation percent of peak expiratory flow of workers on painting day were 11.2 % ±1.8 % and the change average of peak expiratory flow of worker on the post day painting were 7.9 %±1.9. 72%. 72% of the painters had a variation more than 10% of the peak expiratory flow on painting day. All inhalation exposure was 10% more than the threshold standard limits value (tenfold of TLV)
