Identification of Occupational Hazards Factors and Analysis of Critical Control Points in an Electronic Chemicals Project

Objective]By identifying and evaluating the possible occupational hazards factors and damage degree in an electronic chemicals project,to find out the critical control points,study the protective measures,and provide the technical basis for approval of administrative department.Methods]The evaluation was conducted by methods of analogy and quantitative classification.Results]The occupational hazards factors in this construction project were noise,high temperature,chemical poisons and power frequency electromagnetic field.The chemical poisons were main occupational hazards factor,which included ammonia,hydrogen fluoride,hydrochloric acid,sulfide acid,nitric acid,acetic acid,n-butyl acetate and phosphoric acid.Conclusion]The occupational hazards factors in this construction project were complicated,chemical poisons were main hazards factor,and the prevention measure should be strengthened in the critical control points.The comprehensive evaluation showed that the occupational hazard factors in the production process of this project can be controlled and prevented.
