摘要
目的识别某化工厂纺丝车间生产过程中产生的职业病危害因素,确定危害程度,并对职业病危害现状进行分析。方法采用职业卫生现场调查法、检查表法,通过检测检验进行定性和定量分析与评价。结果该车间存在的职业病危害因素有噪声、高温、甲醛、硫酸、氢氧化钠、重铬酸钾等。其中作业场所噪声检测了21个点,强度为58.9~89.8 d B(A),>85 d B(A)的噪声有3个点;对7个工种21人次进行个体噪声检测,其中1个工种3人次的噪声8 h等效声级(L_(EX,8h))超过国家标准要求;高温WBGT指数符合国家标准要求;甲醛浓度在0.87~3.03 mg/m^3,均超标;氢氧化钠、重铬酸钾(按Cr计)未检出,硫酸浓度在0.36~1.90 mg/m^3。结论该车间职业病危害风险分类为严重,职业病危害现状不容乐观,需加强管理,增加工程技术控制措施,改善作业现状。
Objective To identify the occupational hazards in the process of production in the spinning workshop of a chemical plant,define the hazards extent for workers health and analyze the occupational-disease-inductive status. Methods Occupational health field survey,check list,inspection and testing were used for qualitative and quantitative analysis and evaluation. Results Harmful factors in the plant were noise,high temperature,formaldehyde,sulfuric acid,sodium hydroxide,potassium dichromate,etc,in the 21 points of the tested workplaces noise,the strength were58. 9-89. 8 d B（ A）,three points were greater than 85 d B（ A） noise,21 workers on 7 profession had noise test individually,level of LEX,8Hof 3 workers on 1 profession were more than the national standard requirements; high temperature WBGT index complied with the requirement of national standard; formaldehyde concentration in 0. 87-3. 03 mg/m^3 were overweight,sodium hydroxide,potassium dichromate（ Cr） was not detected,sulfuric acid concentration was 0. 36-1. 90 mg/m^3. Conclusion The risk of occupational hazards in the workshop is classified as serious,and the current situation of occupational hazards is not optimistic. It is necessary to strengthen the management,increase the technical control measures to improve the status quo.
