Pre-evaluation of occupational hazards for construction project of ACM production in the chemical company

Objective To identify, evaluate and analyze possible occupational hazard factors in this construction project for predicting the effect on the workers＇ health , provide the feasible and efficient measures against the occupational expo- sure. Methods Analogizing was used by selecting a company which was similar to this construction project. The assess- ment was proceeded by using combination of principle of checklist and analogizing methods. Results This construction pro- ject items including the selection of site, the overall layout, the arrangement and layout of the facilities, occupational dis- ease prevention and protection measures, the hygiene equipment of auxiliary workplaces met the requirements of the national laws and regulations. The main occupational hazard factors that might exist in this construction project were dust, poisonous chemicals （ chlorine, hydrogen chloride and sodium hydroxide） and noise. Qualified rates of dust, hydrogen chloride and noise in the analogy enterprise were all 100. 0%. 11 points of chlorine were detected, and qualified rate was 90. 9%. Conclusion The construction project is serious occupational hazard. The designs of the equipment for the occupational disease hazard control of the construction project meet the national laws and regulations, and this construction project is feasible.
