[目的]了解某钢结构生产企业存在的职业病危害因素和职业病危害防护措施,为职业病防治工作提供依据。[方法]采用现场职业卫生学调查和工作场所职业病危害因素检测方法,进行职业卫生现况调查分析。按照《工作场所空气中有害物质监测的采样规范》,选择有代表性的作业点进行检测,其中粉尘选择9个检测点、毒物选择20个检测点、噪声选择23个检测点、紫外线选择6个检测点。[结果]该企业存在的主要职业病危害因素有粉尘、锰及其无机化合物、二甲苯等有毒物质以及噪声、紫外线等物理因素,其中粉尘合格率为100.0%,紫外强度合格率100.0%,锰及其无机化合物浓度合格率为50.0%,噪声强度合格率为73.9%。[结论]钢结构生产企业主要有粉尘、毒物和噪声等职业病危害因素,企业应采取有效的职业病危害防护措施,制定并严格执行职业健康检查和职业病危害因素监测制度。
[Objective] To understand the occupational hazards and protective measures against occupational hazards in a steel structure manufacturing enterprise, and provide basis for prevention and control of occupational diseases. [Methods] The investigation of occupational health status was conducted by field occupational hygiene survey and detection of occupational hazards in the workplace. In accordance with the “Sampling Specification for Monitoring of Hazardous Substances in Workplace Air”, a representative worksite was selected for testing. Among them, nine test points were selected for dust, 20 test points for poison, 23 test points for noise, and 6 for UV check Point. [Result] The main hazards of occupational diseases in this enterprise included dust, manganese and its inorganic compounds, xylene and other toxic substances as well as physical factors such as noise and ultraviolet radiation. The passing rate of dust was 100.0%, the pass rate of ultraviolet intensity was 100.0% The pass rate of inorganic compounds was 50.0%, and the pass rate of noise was 73.9%. [Conclusion] The steel structure manufacturing enterprises mainly include occupational hazards such as dust, poisons and noise. Enterprises should adopt effective protective measures against occupational hazards and formulate and strictly implement the monitoring system of occupational health checks and occupational hazards.
