目的进行职业病危害现况调查及风险评估,为安全生产监督管理行政部门对用人单位职业病防护设施监督管理和用人单位职业病防治的日常管理提供依据。方法采用职业病危害现场调查及风险评估的方法,对上海市松江区化工行业某塑料制造企业工作场所存在的职业病危害因素及接触水平、防护设施合理性进行现状评价。结果该企业工作场所空气中丙酮具有5级暴露风险等级、中等职业危害风险,检测最高浓度为3600mg/m~3,超限倍数为8,一氧化碳、二氧化氮具有较小职业危害风险,其余职业病危害因素浓度、强度均未超标,在岗工人职业健康检查未出现与职业危害因素相关的异常结果,采取的职业病防护设施对职业病危害因素总体控制较好,但需要进一步完善局部通风设置等措施。结论该企业辊筒、过滤岗位涉及的丙酮为此次风险评估等级最高的职业病危害因素,因而应重点关注上述岗位,应从工程技术措施、职业卫生管理措施和操作规程、应急救援预案、健康监护策略、职业卫生培训等方面进行加强,规范管理,切实保护职工健康。
Objective To investigate the current status of occupational diseases and assess the risks, and provide the basis for supervision and administration of work safety production on the supervision and management of occupational disease prevention facilities and the daily management of occupational disease prevention and control of employing units. Methods Occupational hazards and site risk assessment methods were used to evaluate the current status of occupational hazards and exposure levels and the reasonableness of protective facilities in the workplace of a plastics manufacturing enterprise in Songjiang District of Shanghai. Results Acetone in the workplace air had a level 5 exposure risk and a medium occupational hazard risk. The highest detection limit was 3600 mg / m 3, the limit of multiple was 8, and carbon monoxide and nitrogen dioxide were at a lower risk of occupational hazards. Other occupational diseases The concentration and intensity of hazardous factors did not exceed the standard. Occupational health examination of on-the-job workers showed no abnormal results related to occupational hazard factors. Occupational disease prevention facilities had good overall control over the occupational hazards, but measures such as local ventilation were needed to be further perfected. Conclusion The acetone involved in the roller and filter post of this enterprise is the most hazardous occupational hazard in this risk assessment. Therefore, the above positions should be given special attention. It should be based on engineering and technical measures, occupational health management measures and operating procedures, emergency rescue plans, and health guardianship strategies , Occupational health training and other aspects to strengthen and standardize management, and effectively protect the health of workers.
