某钼精粉冶炼建设项目职业病危害控制效果评价

Control effect of occupational hazards in the construction project of molybdenum concentrate smelting

目的识别并检测某钼精粉冶炼建设项目存在的职业病危害因素,评价该建设项目的职业病危害控制效果,从源头控制或消除职业病危害,防治职业病,保护劳动者健康。方法采用职业卫生现场调查、工程分析、职业卫生检测和职业健康检查等方法进行综合评价。结果粉尘作业岗位合格率为11.1%,噪声作业岗位合格率为46.2%,钼及其化合物及高温作业岗位合格率为100.0%;鄂破工、筛分工、皮带工、球磨工等部分工种接触粉尘浓度与噪声强度超标。结论该建设项目属职业病危害严重建设项目,防护措施存在一定问题,如严格落实整改意见,基本能达到竣工验收条件。

Objective To identify and detect the occupational disease risk factors of a molybdenum metallurgy construction project,and evaluate the control effect of occupational hazard and protect the laborers＇ health from the source. Methods The comprehensive evaluation were based on the comprehensive evaluation of occupational health field investigation,engineering analysis,occupational health detection and occupational health examination method. Results The qualified rate of dust-exposed work was about 11. 1%,the qualified rate of noise-exposed work was about 46. 2%,and the qualified rates of molybdenum and its compounds exposed work and hot environment work were 100. 0%; dust exposure concentration and noise intensity of jaw crasher worker,screener,beltman,ball grinder worker and other parts of professions were beyond standard. Conclusion The construction project is a serious occupational hazards in the construction project,the protective measures exist certain problems,such as the strict implementation of rectification,can basically meet the completion and acceptance conditions.
