目的评价分析某大型燃煤火力发电厂职业病危害及其防护状况,为新建电厂的职业病危害预评价提供依据。方法对该电厂300MW燃煤发电机组进行职业病危害因素监测和职业卫生学调查。结果该厂针对各类职业病危害采取了有效的卫生防护措施。经监测:作业场所粉尘、噪声、高温、有毒气体均符合国家卫生标准要求。结论燃煤电厂的主要职业病危害为粉尘、噪声和高温,由于大型燃煤电厂自动化程度高,职业卫生防护设施完善,只要重视职业卫生工作,就可以有效控制和消除燃煤火力发电厂职业病危害。
Objective To evaluate and analyze the occupational hazards and protection status of a large coal-fired power plant and provide the basis for pre-evaluation of occupational hazards in new power plants. Methods Monitoring 300MW coal-fired generating units in this power plant and occupational hygiene investigation. Results The factory for all kinds of occupational hazards have taken effective health protection measures. The monitoring: workplace dust, noise, high temperature, toxic gases are in line with national health standards. Conclusion The main occupational hazards of coal-fired power plants are dust, noise and high temperature. Due to the high degree of automation of large coal-fired power plants and the improvement of occupational health protection facilities, as long as occupational health care is taken seriously, the occupational hazards of coal-fired thermal power plants can be effectively controlled and eliminated.
