Evaluation on control effect of occupational hazards of the technical innovation project in a zinc smelting plant

[Objective]To analyze the possible occupational hazard factors of the construction project in a zinc smelting plant,assess the protective measures of occupational hazards and its effect,and put forward the feasible preventive strategies.[Methods]By using the field occupational survey and detection,the evaluation was carried out according the relevant national regulations and standards.[Results]All of the location,production technology,facility layout,protective facilities for occupational diseases,individual protective articles,occupational health management and auxiliary rooms met the relevant national standards.The main occupational hazard factors were coal dust,lead fume,lead dust,cadmium,zinc,CO,CO2,SO2,sulfuric acid,ammonia,nitrogen oxides,noise and power frequency electromagnetic field.The detection results of most monitoring points accorded with the national standards except few monitoring points.[Conclusion]This construction project has high level of automation,and the occupational protection strategies and production management measures are feasible.
