Application of occupational health risk assessment model in a glyphosate manufacturing enterprise / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To assess the occupational hazard risks of glyphosate in a pesticide factory by MOM and ICMM models, and to explore the suitable method.@*Methods@#A large glyphosate enterprise was selected and an industrial hygiene survey was conducted. MOM and ICMM models were applied to evaluate the occupational hazard risks, which were compared with the site testing results and verified by the national occupational hazard classification for workplaces.@*Results@#There were poor occupational health protection facilities in the plant. The concentrations of glyphosate in drying and packaging posts were beyond occupational exposure limit. And the maximum individual detection values were 5.32 mg/m3 and 49.59 mg/m3, respectively. The results of MOM and ICMM risk rating method were consistent. The main posts were low and medium risk. The quantitative method of ICMM judged that nearly all posts were unacceptable risks. There was no difference in the risk ratio between MOM and risk rating method as well as work grading criteria (F=3.960, P>0.05) , while the result calculated by quantitative method in evaluating the production process of IDA technology was obviously higher than that of the former three methods (F=4.096, P<0.05) .@*Conclusion@#Both MOM and ICMM models can appropriately predict and assess the occupational health risk of glyphosate. Besides, the judgment results may be more precise than the classification of occupational hazards. Due to the relatively simple operation, easy evaluation parameters, ICMM model maybe more convenient for glyphosate production plants.
