目的识别、分析和评价某微型车制造企业职业病危害因素及危害程度,找出职业病危害因素关键控制点,以便有针对性地采取防护对策和管理措施。方法采用经验法、系统分析法和调查、检测法进行识别与评价。结果某微型车制造企业存在粉尘、化学性毒物和噪声等多种职业病危害,以电焊烟尘、苯和噪声等为主,尤其是噪声危害最为严重,达标率仅有36.0%～55.5%,最大日平均8 h等效声级达到100.6 dB(A)。结论电焊烟尘、苯和噪声均为该企业职业病危害因素关键控制点,以噪声更为重要。
Objective To identify, analyze and evaluate the occupational hazards and hazards of a mini-car manufacturing enterprise and find out the key control points of occupational hazards in order to take targeted protective measures and management measures. Methods Empirical method, system analysis method and investigation, detection method to identify and evaluate. As a result, there was dust, chemical poison, noise and other occupational hazards in a mini-vehicle manufacturer. The main problems were welding fume, benzene and noise, especially the noise was the most serious, with the compliance rate of only 36.0% -55.5% The average sound level of 8 h reaches 100.6 dB (A). Conclusion Welding fumes, benzene and noise are the key control points of occupational hazards in this enterprise. Noise is more important.
