摘要
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 disease hazards and assess the risks,and provide basis for supervision and management of relevant departments on occupational-disease-prevention facilities and daily management of enterprise on occupational disease prevention and control. [Methods]By methods of field investigation of occupational disease hazards and risk assessment,the occupational hazard factors existing in workplace,exposure level and rationality of protective facilities in a plastic manufacturing enterprise of chemical industry in Songjiang district of Shanghai were investigated and evaluated.[Results]The exposure risk level of acetone in workplace air of the enterprise was 5;occupational hazard risk was medium;highest detection concentration was 3 600 mg/m^3,and the excursion limits was 8. The carbon monoxide and nitrogen dioxide had less risk of occupational hazards,and the concentration and intensity of other occupational hazard factors didn ＇t exceed the standard. The abnormal results related to the occupational hazard factors were not found in occupational health examination of workers. The control effect of occupational-disease-prevention facilities on occupational hazard factors is better,but the local ventilation settings and other measures needed to be further perfected. [Conclusion]The acetone in roller and filter posts in this enterprise was the occupational hazard factor with the highest risk assessment level,therefore the above posts should be focused on. The management of engineering measures,occupational health management measures,operating rules,emergency rescue plan,health care strategy and occupational health training should be strengthened to protect the health of workers.
