某铅酸蓄电池装配企业职业病危害现状调查

Status Investigation on Occupational Hazards in Lead-Acid Battery Assembly Corporation

目的了解某铅酸蓄电池装配企业职业病危害现状,确保工人的生产安全和身体健康。方法通过职业卫生现场调查、职业卫生检测等方法收集数据和资料,并结合职业病防护设施、个人职业病防护水平和定量分级结果,对试运行期间的作业人员的职业病危害因素接触水平及职业健康影响进行评价。结果本企业存在的职业病危害因素有二氧化锡、砷及其无机化合物、铅烟、锑及其化合物、铜烟、硫酸、苯、苯乙烯、甲苯、甲基丙烯酸甲酯、乙酸丁酯、噪声等。检测结果表明,部分工种铅烟(CTWA0.15～0.41 mg/m3)、二氧化锡(CTWA2.52～3.80 mg/m3)超过国家卫生标准。对其防护设施进行改造后,各工种接触职业病危害因素的浓度均符合国家卫生标准的要求。结论本项目职业病防护设施改造前职业病危害严重,对职业病防护设施进行改造后,作业场所作业人员接触职业病危害因素的浓(强)度均符合国家卫生标准。

Objective To understand the status of occupational hazards in the lead-acid battery factory,to ensure workers′ safety and health.Methods The ways including the field investigation of occupational health,occupational health testing and other methods to collect data and information were carried out,combined with occupational protective equipment,personal protection levels of occupational diseases and the results of quantitative grading,the evaluation of the exposure levels of occupational hazards during the trial operation.Results The occupational hazards existed in the corporation were tin dioxide,arsenic and its inorganic compounds,lead fume,antimony and its compounds,copper fume,sulfuric acid,benzene,styrene,toluene,methyl methacrylate,butyl acetate and noise.The testing results showed that lead fume（C TWA 0.15-0.41 mg/m^3）,tin and its compounds（C TWA 2.52-3.80 mg/m^3）in some posts exceeded national hygienic standards,after having transformed its protection facilities,the various types of occupational hazards in the concentration of exposure to all kinds of workers were in line with national standards.Conclusion The occupational hazards in the project are serious before transforming prevention facilities.After the transformation the exposure to occupational hazards of workers in concentration（intensities） is in line with national hygienic standards.
