某焦化厂职业病危害现况评价

Evaluation of Occupational Hazards in A Coking Plant

目的了解与分析评价某焦化厂的职业病危害现况,为制定防治措施提供依据。方法采用现场卫生学调查、类比法、经验法和职业健康检查等方法对煤矿进行评价。结果该焦化厂的选址与总体布局、生产设备布局、职业病防护设施、个人使用的防护用品、职业卫生管理、卫生辅助用室设置等符合国家有关规定;该焦化厂生产过程中可产生煤尘、其他粉尘、硫化氢、氨、碳氧化物、氮氧化物、苯和苯并(a)芘、萘、酚类化合物、二硫化碳、氰化氢、焦炉逸散物、噪声、振动、高温和热辐射等职业病危害因素,其中部分岗位粉尘作业危害达到Ⅰ级,噪声作业危害达到Ⅱ级。结论该厂的职业病危害控制措施可行、有效,但部分岗位仍需加强治理。

[Objective]To understand and evaluate the status of occupational hazards in a coking plant,and provide evidence for developing control measures. [Methods]Field hygienic investigation,analogy,experience method and occupational health examination were applied to conduct evaluation on the coking plant. [Results]Related factors including site selection,the overall layout,the facilities layout,occupational disease preventive and protective measures,the individual protection facilities,the occupational health management,the auxiliary room facilities all accorded with the national regulations;the production process in the coking plant could generate coal dust,other dust,hydrogen sulfide,ammonia,carbon oxides,nitrogen oxides,benzene and benzo（a） pyrene,naphthalene,phenolic compounds,bisulfide carbon,hydrogen cyanide,coke oven emissions,noise,vibration and heat and thermal radiation,among which dust exposure reached the level I and noise reached level II at some working posts. [Conclusion]The control measures against occupational hazards in this coking plant are feasible and effective,but management should be enhanced in some working posts.
