广西某石油炼化企业VOCs处理装置改造工程职业病危害控制效果评价

Evaluation of occupational hazard control effect of VOCs treatment unit transformation project in a petroleum refining enterprise in Guangxi

目的通过对广西某石油炼化企业挥发性有机物(volatile organic compounds,VOCs)处理装置改造工程进行职业病危害控制效果评价,为企业职业病危害因素防控提供依据。方法2021年3—6月,开展职业卫生现场调查和现场检测,对企业进行职业病危害控制效果评价。结果生产过程中产生的职业病危害因素主要有硫化氢、苯、甲苯、二甲苯、溶剂汽油和噪声,所测职业病危害因素合格率为100%。职业病防护设施、个体防护用品及应急救援设施配备情况符合国家相关法律法规要求。职业健康检查未发现职业相关异常患者。结论本项目职业病危害风险分类为一般。正常生产过程中管道、阀门泄漏或设备磨损易发生泄漏事故;定期检维修或更换填料为受限空间作业,可能发生急性中毒事故。故本项目投产后应严格落实各项应急救援措施,加强职业卫生管理,确保作业人员的职业健康。

Objective Through the evaluation of occupational hazard control effect of volatile organic compounds(VOCs)treatment unit transformation project of a petroleum refining and chemical enterprise in Guangxi,to provide a basis for the prevention and control of occupational hazard factors of the enterprise.Methods From March 2021 to June 2021,the on-site investigation and detection of occupational health were conducted,to evaluate the control effect of occupational hazards in the enterprise.Results The occupational hazard factors produced in the production process mainly included hydrogen sulfide,benzene,toluene,xylene,solvent gasoline and noise.The test results show that the qualified rates of the measured occupational hazard factors were100%.The allocation of occupational disease prevention facilities,personal protective articles and emergency rescue facilities met the requirements of relevant national laws and regulations.No occupational related abnormalities were found in occupational health examination.Conclusions The risk of occupational hazards of the project is classified as general.The leakage accidents are easy to occur due to pipeline and valve leakage or equipment wear during normal production.The regular inspection,maintenance or replacement of filler is confined space operation,which may lead to acute poisoning accidents.Therefore,after the project is put into operation,various emergency rescue measures should be strictly implemented,and occupational health management should be strengthened to ensure the occupational health of operators.
