医用PVC粉尘爆炸风险评估

Medical PVC Dust Explosion Risk Assessment

近年来粉尘爆炸事故频发于多行业,随着医用PVC粉产量增加,医用PVC粉生产企业也在考虑粉尘爆炸的风险。本文以某医用PVC粉企业为研究对象,首先对其生产工艺和设施设备进行了解;其次现场取样PVC粉尘,测试其爆炸敏感度,评估其着火危险性,并与几种常见的粉尘爆炸敏感度进行对比,发现医用PVC粉尘属于难燃性粉尘;然后结合现场的粉尘释放源、点火源、安全管理综合评估该医用PVC粉尘的爆炸风险;最后提出了防控粉尘爆炸的建议。

In recent years,dust explosion accidents have occurred frequently in many industries.As the output of medical PVC powder increases,medical PVC powder production enterprises are also considering the risk of dust explosion.This article takes a medical PVC powder enterprise as the research object,firstly understands its production process and facilities and equipment;secondly samples PVC dust on site,tests its explosion sensitivity,evaluates its fire hazard,and compared with several common dust explosion sensitivities,it was found that medical PVC dust is a non-flammable dust;then the explosion risk of the medical PVC dust is comprehensively evaluated in combination with the on-site dust release source,ignition source,and safety management;finally,suggestions for preventing and controlling dust explosion are proposed.
