[目的]分析降噪设备及系统研制项目存在的职业病危害因素,评价职业病防护措施,提出合理可行的职业病防护建议。[方法]通过职业卫生现场调查,对主要职业病危害因素开展检测与分析,对该项目职业病危害进行综合评价。[结果]项目主要存在的职业病危害因素有噪声、工频电场、高频电场、电焊弧光、电焊烟尘、砂轮磨尘、其他粉尘、一氧化碳、二氧化氮、锰及其无机化合物、金属镍与难溶性镍化合物、臭氧、三氧化铬、二甲苯。经检测,作业场所噪声合格率为88.9%,其余均符合职业接触限值的要求。[结论]降噪设备制造属于职业病危害较重的建设项目,其关键控制点为电焊、喷漆、玻璃棉包装及打磨岗位。
[Objective] To analyze the harm factors of occupational diseases in noise reduction equipment and system development projects, evaluate occupational disease protection measures and put forward reasonable and feasible suggestions on occupational disease protection. [Methods] Through occupational health field investigation, the main occupational hazards were detected and analyzed, and the occupational hazards of the project were evaluated comprehensively. [Results] The major hazards of occupational diseases in the project were noise, power frequency electric field, high frequency electric field, arc welding, welding dust, wheel dust, other dust, carbon monoxide, nitrogen dioxide, manganese and their inorganic compounds, Soluble nickel compounds, ozone, chromium trioxide, xylene. After testing, workplace noise passing rate of 88.9%, the rest are in line with the requirements of occupational exposure limits. [Conclusion] The construction of noise reduction equipment belongs to the construction projects with heavy occupational hazards. The key control points are electric welding, painting, glass wool packaging and grinding jobs.
