摘要
近年来由于熏蒸散气而产生的仓内安全事故引起了行业乃至社会各方的高度关注,但熏蒸散气阶段的作业安全研究较少,相关隐患尚未被深入研究以及重视。在实仓实验中,对高大平房仓磷化氢熏蒸和散气过程仓房内外环境空气中磷化氢浓度进行现场检测,探讨熏蒸、散气作业过程的有效安全防护距离以及防护措施,研究结果为防范熏蒸作业安全事故、减少或避免发生人身伤害和经济损失提供依据。研究结果表明,安全防护距离与仓内(粮堆内)磷化氢气体浓度大小有关,不能完全以固定的安全防护距离作为判定是否安全的依据,接近熏蒸散气区域前必须检测磷化氢浓度。
In recent years,the safety accidents in warehouses caused by fumigation and exhaust have attracted great attention by people from grain industry and society.But there are few literature reports on safety during fumigation and exhaust operation,which needs to be further researched and pay more attention.The concentration of phosphine both inside and outside of the warehouse were detected in real warehouse experiment during fumigation and exhaust operation to explore the effective safety protection distance and protective measures,in order to provide reference for strengthening safety precautions against the safety accidents,reducing or avoiding personal injury and economic loss.The results show that the safety protection distance is related to the concentration of phosphine gas in the warehouse(in the grain pile),and the fixed safety protection distance can not be used as the basis to judge whether it is safe or not.The concentration of phosphine must be detected before approaching the fumigation area.
