目的对作坊式宝石加工场所粉尘危害防控综合干预措施进行效果评估,为该行业粉尘危害防控提供科学依据。方法因地制宜建立起作坊式宝石加工场所粉尘防控综合干预措施,对干预前后的作业场所空气中粉尘浓度、接尘工人职业健康检查结果、职业卫生培训出勤率、职业卫生知识知晓率、个人防护等情况进行检测、调查、分析和评价。结果干预后该作业场所硬件设施得到一定程度的改善,作业场所空气中粉尘浓度大幅下降,其合格率从干预前的87.04%提高到干预后的97.29%(P<0.05);接尘工人职业健康检查结果、职业卫生培训出勤率、职业卫生知识知晓率、个人防护行为均较干预前显著改善(P<0.05)。结论实施干预措施有效地改善了作坊式宝石加工场所粉尘作业环境,今后应注重粉尘危害的源头治理工作,进一步降低粉尘危害。
Objective To evaluate the effectiveness of dust hazard prevention and control intervention in workshop-type gem processing sites and provide a scientific basis for the prevention and control of dust hazards in this industry. Methods The dust prevention and control interventions for workshops and gemstones processing workshops were established according to local conditions. The dust concentrations in the air before and after the intervention, occupational health examination results of workers exposed to dust, occupational health training attendance, occupational health awareness, personal protection and so on Situation detection, investigation, analysis and evaluation. Results After the intervention, the hardware facilities of the workplace were improved to a certain degree. The dust concentration in the air of the workplace dropped sharply, and the pass rate increased from 87.04% before intervention to 97.29% after intervention (P <0.05). Occupational health The examination results, occupational health training attendance rate, occupational health awareness rate and personal protective behavior were significantly improved compared with those before intervention (P <0.05). Conclusion The implementation of the intervention measures effectively improved the dust environment for the workshop-type gem processing sites. In the future, attention should be paid to the source control of dust hazards to further reduce the dust hazard.
