某公司涂料生产项目职业病危害控制效果评价

目的识别和分析某涂料生产项目产生的职业病危害因素的种类和程度,分析和评价其职业病危害防护措施及效果。方法通过职业卫生现场调查、职业病危害因素检测、职业健康检查、检查表分析法等方法对该项目进行评价。结果该企业在生产过程中存在的职业病危害因素有化学毒物〔苯、甲苯、二甲苯、乙酸乙酯、乙酸丁酯、环己酮、二异氰酸甲苯酯（TDI）〕,粉尘（滑石粉尘、二氧化钛粉尘、其他粉尘）,噪声。检测结果表明：化学毒物中苯、甲苯、二甲苯、乙酸丁酯、环己酮、TDI的短时间接触浓度（STEL）和时间加权浓度（TWA）的检测结果均符合国家卫生标准要求。仅有化学毒物乙酸乙酯STEL的检测结果超出国家卫生标准要求,检测结果为12.18~340.69mg/m3,在10个检测点中有1个检测点超标。粉尘浓度和噪声强度均符合国家卫生标准限值。结论在确保各类防护设施有效运行、保证生产设备的正常运转的情况下,该项目在职业病危害控制方面是可行的。

Control effect of occupational hazards in the production project of a paint company

Objective To identify and analyze the types and levels of occupational hazards existed in the paint production project , evaluate the occupational diseases prevention measures and effect. Methods The project was evaluated by the methods of occupational field investigation, detection, occupational health examination and checklist. Results The occu- pational hazards included toxic chemicals such as benzene, toluene, xylene, ethyl acetate, butyl acetate, cyclohexanone, toluene diisocyanate （TDI） , dust （talcum powder, titanium dioxide dust and other dusts） and noise. Test results showed that the short exposure concentrations （C_STEL） and the time weighted average concentrations（ CTWA ） of benzene, toluene, xylene, butyl acetate, cyclohexanone and TDI were in line with national health standards. C_STEL （12. 18 -340. 69 mg/m3） of ethyl acetate exceeded the allowable exposure limits of national standards in one monitoring point of 10 test points. Conclusion The project is feasible from the view of occupational health. The project is the effective protective measures and the normal operation of production equipments.
