[目的]评价某热电厂职业病危害控制效果。[方法]通过现场调查、工作场所职业病危害因素现场检测,分析职业病危害控制效果。[结果]工作场所中CO、NO、NO2、SO2、盐酸、氢氧化钠、氨、肼等毒物浓度均低于职业接触限值,粉尘合格率为79.1%,噪声合格率为70.6%,作业环境温度合格率为84.6%,工频电场合格率达100.0%。[结论]粉尘、噪声是该厂主要的职业病危害因素,应重点控制;该建设项目对职业病危害的控制措施基本可行和有效。
[Objective] To evaluate the control effect of occupational hazards in a thermal power plant. [Method] Through on-the-spot investigation and on-site detection of occupational hazards in the workplace, the control effects of occupational hazards were analyzed. [Result] The concentrations of CO, NO, NO2, SO2, hydrochloric acid, sodium hydroxide, ammonia and hydrazine in the workplace were lower than the occupational exposure limits, the passing rate of dust was 79.1% and the passing rate of noise was 70.6% Temperature pass rate of 84.6%, power frequency electric field pass rate of 100.0%. [Conclusion] Dust and noise are the main occupational hazards in this plant, and should be given priority control. The control measures of occupational hazards in this project are basically feasible and effective.
