目的分析某通信元件公司在运行期间存在的职业病危害因素及危害程度,确定职业病危害关键控制点。方法采用检查表法、职业卫生调查法、检测检验法、工程分析法相结合对职业病危害进行识别和分析。结果在生产过程中存在的主要职业病危害因素有化学毒物(苯、甲苯、二甲苯、乙苯、苯乙烯、丁醇、异丙醇、锡烟和铅烟等)、粉尘、高温、噪声等。职业病危害因素监测结果显示,化学毒物检测结果中D栋喷漆房二甲苯浓度超出国家卫生标准,其余符合国家卫生标准;粉尘浓度全部符合国家卫生标准;噪声强度检测130个点,其中6个检测点(占4.6%)噪声强度超过85 d B(A),冲床房的噪声强度最大,达95.6 d B(A);个体噪声强度检测15个工作岗位,其中有5个岗位超过职业卫生限值。结论该项目职业病危害因素较复杂,其主要职业病危害因素为噪声、二甲苯和异丙醇,应从职业病危害的关键控制部位加强职业病防治工作。
Objective To analyze the hazard factors and occupational hazards existing in a communication element company during operation and determine the key control points of occupational disease hazards. Methods The method of checklist, occupational health survey, test and test, and project analysis were used to identify and analyze occupational hazards. Results The main occupational hazards in the production process were chemical poison (benzene, toluene, xylene, ethylbenzene, styrene, butanol, isopropanol, tin and lead smoke), dust, high temperature and noise. Occupational disease risk factors monitoring results show that the chemical toxicity test results D building spray paint room xylene concentration exceeds the national health standards, and the rest in line with national health standards; dust concentrations all meet the national health standards; noise intensity detection of 130 points, of which 6 detection points (4.6%), the noise intensity exceeded 85 d B (A), and the noise intensity of the press room reached the maximum of 95.6 d B (A). Individual noise intensity detected 15 work positions, of which 5 exceeded the occupational health limit. Conclusion The risk factors of occupational diseases in this project are complicated. The major occupational hazards are noise, xylene and isopropanol. Occupational disease prevention and control should be strengthened from the key control sites of occupational hazards.
