目的评价车间采用上进风方式的排风效果。方法检测车间代表性岗位的风速、化学性职业病危害因素物质浓度,以评价该种排风系统的有效性。结果该车间12个风速测定点中有两个不合格,合格率为83.3%。化学性危害因素检测合格率为100%。结论对于化学性职业病危害因素较多的化工企业,采用上进风方式排风的效果较好。
Purpose To evaluate the exhaust effect of the upwind approach in the workshop. Methods The wind speed and the chemical concentration of chemical occupational hazards were detected in the representative job shop to evaluate the effectiveness of the exhaust system. Results Two of the 12 wind speed measurement points in the workshop failed, with a pass rate of 83.3%. Chemical hazard testing pass rate was 100%. Conclusion For chemical enterprises with more chemical occupational hazards, the effect of using the upper air intake to exhaust air is better.
