【摘要】 目的对某燃煤电厂噪声危害进行分析,评估其噪声危害的程度。方法采用现场调查、噪声检测和职业健康检查等方法对燃煤电厂噪声危害进行综合性评估。结果 50个接噪岗位中17个岗位(34.0%)个体噪声超过职业接触限值85 d B(A),106个作业场所中63个检测点(59.4%)噪声强度超过85 d B(A),并出现1名噪声职业禁忌证和6名疑似职业病者(双耳语频听力、高频听力损伤)。结论该燃煤电厂噪声危害较重,应加强噪声防护,配备防噪耳塞,定期进行职业健康检查,保障作业人员职业健康。更多还原

【Abstract】 [Objective]To analyze the noise hazards in a coal-fired power plant,and evaluate its harmful degree. [Methods]Field investigation,noise test and occupational health examination,were adopted to evaluate noise hazards comprehensively.[Results]Of 50 posts exposed to noise,17(34.0%)posts’ noise intensity exceeded occupational exposure limit of 85 d B(A). Noise intensity of 63 detection points(59.4%)exceeded 85 d B(A)in 106 workplaces. There were 1 case of noise occupational contraindication and 6 cases of suspected occupational disease(hearing loss of double whisper listening,high frequency).[Conclusion]Noise hazard was serious in this coal-fired power plant. It is necessary to enhance noise protection,to equip deadening earplugs,to perform occupational health examination at regular intervals,so as to guarantee the occupational health of workers.更多还原
