目的分析某计算机通讯电子设备新建企业生产过程中存在的职业病危害因素及其危害程度,确定职业病危害的关键控制点。方法采用职业卫生调查、职业卫生检测、职业健康检查等方法进行识别。结果该厂房存在化学毒物、粉尘、噪声、高温、激光、工频电磁场。现场检测粉尘浓度0.9～15.2 mg/m3,噪声强度63.2～91.6dB(A),粉尘和噪声均有少数岗位超标,针对超标点超标原因整改后复检结果符合职业接触限值要求,其余化学毒物、高温、工频电磁场的浓度或强度均符合职业接触限值要求。职业健康检查发现少数接触噪声人员听力异常。结论根据职业病危害的分布及治理的重点与难点筛选关键控制点,该企业须重视和做好关键控制点的管理与防治措施,使职业病发生的风险概率降低。
Objective To analyze the hazard factors of occupational diseases and their harmfulness in the process of manufacturing new computer communication electronic equipment and to determine the key control points of occupational hazards. Methods Occupational health survey, occupational health examination, occupational health examination and other methods were used to identify. Results The plant has chemical poison, dust, noise, high temperature, laser, power frequency electromagnetic field. The dust concentration and noise of on-site testing dust concentration 0.9 ~ 15.2 mg / m3, 63.2 ~ 91.6dB (A), the dust and noise are a few more than the standard, the rectification of rectification results for the exceeding the standard point results meet the occupational exposure limit requirements, the remaining chemical poisons , High temperature, power frequency electromagnetic field concentration or intensity are in line with occupational exposure limits. Occupational Health Examination found that a small number of people exposed to noise hearing abnormalities. Conclusion According to the distribution of occupational hazards and the key points of control and difficulty screening of key control points, the enterprises should pay attention to and do a good job in the management and prevention and control measures of key control points so that the risk probability of occupational diseases is reduced.
