目的对油田某重晶石粉厂粉尘作业环境干预措施进行效果评价。方法对干预前后粉尘作业环境空气中粉尘浓度,作业工人职业健康检查结果、职业卫生知识知晓率、个人防护行为的情况进行检测,分析和效果评价。结果干预后该粉尘作业环境空气中粉尘浓度,作业工人职业健康检查结果、职业卫生知识知晓率、个人防护行为均较干预前显著改善,干预前后比较,差异有统计学意义(P<0.05)。结论实施本干预措施可以起到有效的防尘效果,有利于改善作业工人的健康。
Objective To evaluate the effect of environmental intervention on the dust environment of a barite powder factory in the oilfield. Methods The dust concentration in the dust environment, occupational health examination results, occupational health awareness and personal protection behavior in the dust environment before and after intervention were detected, analyzed and evaluated. Results After the intervention, the airborne dust concentration, occupational health examination results, occupational health awareness and personal protection behaviors of the dust environment were significantly improved compared with those before the intervention. There was significant difference between before and after the intervention (P <0.05). Conclusion The implementation of this intervention can play an effective anti-dust effect and help to improve the health of workers.
