Objective To confirm the occupational risk factors and exposure levels existed in the construction project,put forward countermeasures and suggestions of occupational health supervision for the government and enterprises and provide a scientific basis for the daily management of the occupational disease prevention and control. Methods The project was evaluated by collecting relevant information site investigation,occupational health and occupational health inspection,occupational health examination and check table method. Results The main occupational risk factors were the welding soot,grinding wheel grinding dust,dust,manganese and other compounds,nitrogen oxides,ozone,coal tar pitch volatiles,noise,high temperature and ultraviolet radiation. Time weighted average concentration of Braided chains flash welding was5. 58 mg / m~3,more than PC-TWA limits; The noise at woven chain section was 88. 1-89. 7 d B( A),exceeding the occupational exposure limits; The rest of the dust concentration of each position,concentration of poison,noise intensity,high temperature WBGT index,ultraviolet irradiance all conformed to the requirements of the occupational health standards; The occupational health coverage was low,2 workers were found suspected occupational diseases,1 worker was occupational contraindication. Conclusion This enterprise belongs to the serious occupational risk item,occupational hazard protection measures and basic conform to the requirements of the occupational health,the key control points include flash welding dust protection woven chain,chain section noise and high temperature protection and varnished poison protection operation.
