某热电厂职业病危害现状调查分析

Investigation on Occupational Hazards Analysis of a Cogeneration Plant

目的调查热电厂作业场所危害因素分布特点及浓度,结合作业人员职业健康检查结果,探究各类职业病危害因素对作业人员健康的影响。方法采用现场职业卫生学调查对热电厂各车间职业病危害因素进行识别,依据作业场所各类职业病危害因素健康效应、现场检测浓度和强度,结合作业人员近2年职业健康检查结果进行对照分析。结果作业场所各类化学物质检测浓度均符合国家卫生限值要求,粉尘个别检测值超过卫生限值要求;个体噪声检测强度超出卫生限值要求;近2年职业健康检查结果显示,每年均筛检出噪声岗位职业禁忌证患者,且血压升高和肺功能异常人数有所增加。结论热电厂作业工人听力异常受作业场所高噪声影响较明显,肺功能异常可能受粉尘、氢氧化钠、盐酸、氨等职业病危害因素影响。

Objective This study aimed to explore the influence of various occupational hazards of the health, by investigation of distribution eharacleristics and concentration of various occupalional hazards and occupational health check in cogeneration plant. Methods On-site occupational health investigation of a polyester compound device to identify occupational hazards, according to various occupational hazard in the workplace health effects, on-site detection of concentration and intensity, combined wilh the operations staff 2 years recently the results of a comprehensive occupational health checks were analyzed. Result Results of operations on-site detec- tion of chemical hazards concentration limits were in line with national standards for noise intensity be- yond detection limit requirements; in 2 years recent- ly, the resuhs showed that occupational patients with contraindication were screened oul evely year, while there was a rising number of trends in blood pressure and increase the number of abnormal hmgs funciion. Conclusion Abnormal hearing in workers affected by high noise more obvious, dust, sodium hydroxide, hydrochloric acid, ammonia and other occupational hazards for workers exposed may lead to abnormal hmgs function.
