The Pre-Assessment of Occupational Hazards in Construction Project of Oil Product Pipeline

Objective To identify, analyze and assess occupational risk factors possibly existed in the construction project. Methods The assessment was proceeded by using combination of checklist and analogy. Results The construction site, overall layout, protective measures of occupational diseases, hygiene auxiliary rooms, personal protective equipments, the management system on industrial hygiene and emergency rescue measures accorded with the hygiene requirements. The concentrations or intensities of all risk factors accorded with the national standards. STEL for dust was 1.3 - 2. 7 mg/m^3 ,the STELs of gasoline,benzene,toluene,xylene,CO, CO2 ,Mn were 0 -230,0 - 1.49,0 -0. 34, 〈0. 10, 〈0. 009, 0. 067,0. 07 -0. 15 mg/m^3 ,respectively. The values of noise and power frequency field were below the allowable values of national standards. Conclusion The project is a common occupational hazard project, the occupational risk factors are able to be controlled and prevented during operation. From the view of occupational health, this project is feasible.
