Objective To classify major productive jobs in an iron and steel enterprise according to occupational hazards and to provide scientific evidence for occupational health classification management.
Methods Based on the surveillance results of occupational hazards during 2012-2014, we firstly classified the productive jobs into five levels by the national classification standard of occupational hazards, then merged into three categories including minor, moderate, and severe levels of occupational hazards, and proposed management measures towards job classification.
Results The occupational hazards in the selected enterprise included industrial dust (weld fume, coal dust, silica dust, lime stone dust, and others), industrial toxicants (carbon monoxide, sulfuric acid, hydrochloric acid, gasoline, benzene, hydrogen cyanide, cyanide, ammonia, hydrogen sulfide, arsenic, chromium, and coke oven emissions), and harmful physical factors (noise, high temperature, X ray, and γ ray). Noise and high temperature were the main occupational hazards according to the classification of occupational hazards at workplaces. There were 669 (54.5%), 271 (22.1%), and 288 (23.4%) jobs merged into minor, moderate, and severe occupational hazard classes, respectively.
Conclusion The simplified job classification is more practical than the previous one, and it can provide effective evidence for occupational health classification management.
