某机械厂玻璃钢车间职业病危害调查

Investigation on occupational hazards in glass fiber reinforced plastic workshop of a machinery plant

目的通过调查某玻璃钢生产车问的职业病危害因素，对该车间的职业病预防控制措施提出建议。方法调查该车间存在的职业病危害物质，检测作业岗位职业病危害物质的浓度或强度，判断危害程度。结果该车间玻璃钢生产岗位环氧氯丙烷浓度合格率为0，最高检测值达90．0mg／m2，各岗位超标达1．65—44．00倍；机加工岗位玻璃钢粉尘合格率为75％，最高检测值达32．0mg／m2，超标4．33倍。结论厂方须对玻璃钢生产和机加工岗位加装排气罩，给工人发放防尘防毒口罩，合理安排巡视时间，有效防控职业病危害。

[ Objective]To investigate the occupational hazard factors in a glass fiber reinforced plastic production workshop, put forward the occupational prevention and control measures in this workshop. [ Methods ] The occupational hazard substances in this workshop were investigated, and the concentrations （ intensities） of occupational hazard substances in operation sites were detected, to judge the degree of damage. [ Results] The qualified rate of epoxy chloropropane concentration in glass fiber reinforced plastic production posts was 0, the highest value was 90.0 mg/m3 , and the values in different posts were 1.65- 44.00 times higher than the standard. The qualified rate of glass fiber reinforced plastic dust in machining positions was 75%, and the maximum detection value reached 32.0 mg/m m3 , which was 4.33 times higher than the limit. [ Conclusion] The plant should install the exhaust hood in glass fiber reinforced plastic production and machining positions, issue the dust-proof respirators to workers, and arrange the inspection time reasonably, so as to effectively prevent and control the occupational hazards.
