Control Effect on Occupational Hazards in Construction Project of the Alumina Plant

Objective To identify, assess and control the occupational risk factors in the construction project, and provide scientific evidences for the inspection by health administrative departments on this construction project. Methods According to Hygienic Standards for the Design of Industrial Enterprises （ GBZ 1 - 2002） and Specifications of Air Sam- pling for Hazardous Substances Monitoring on the Workplace（ GBZ 159 -2004 ）, sites were chosen and risk factors of occu- pational diseases were evaluated by the methods of field investigation, monitoring and quantitation classification. Results Contents of this construction project including the selection of site, the overall layout, the arrangement and layout of the facilities, occupational disease prevention and protection measures, the facilities of auxiliary rooms accorded with the requirements of laws and specifications for occupational health. The main occupational risk factors in the construction project were dusts, poisonous chemicals, noise and vibration, high - temperature, heat radiation, power frequency electric field, and radioactive hazards. The qualified rates of TWA and STEL for dust were 87.2% and 82. 1% ; the qualified rate of noise monitoring was 83. 3% ; values of poisonous chemicals met the requirements of national standards. Conclusion The protective measures on occupational diseases in the construction project axe feasible and effective.
