干粉灭火器

灭火原理:利用压缩的二氧化碳吹出干粉(主要含有碳酸氢钠)来灭火。

适用范围:可扑灭一般火灾,还可扑灭油,气等燃烧引起的失火。

干粉灭火器是利用二氧化碳气体或氮气气体作动力,将简内的干粉喷出灭火的。干粉是一种干燥的、易于流动的微细固体粉末,由能灭火的基料和防潮剂、流动促进剂、结块防止剂等添加剂组成。主要用于扑救石油、有机溶剂等易燃液体、可燃气体和电气设备的初起火灾。干粉灭火器按移动方式分为手提式、背负式和推车式三种。

使用外装式手提灭火器时,一只手握住喷嘴,另一只手向上提起提环,干粉即可喷出。

使用推车式灭火器时,将其后部向着火源(在室外应置于上风方向),先取下喷枪,展开出粉管(切记不可有拧折现象),再提起进气压杆,使二氧化碳进入贮罐,当表压升至 0 . 7 兆帕~ 1 兆帕时,放下进气压杆停止进气。这时打开开关,喷出干粉,由近至远扑火。如扑救油类火灾时,不要使干粉气流直接冲击油渍,以免溅起油面使火势蔓延。

使用背负式灭火器时, 应站在距火焰边缘 5 米~ 6 米处,右手紧握干粉枪握把(若为氮气动力,则只能握住木制把手,否则可能被低温气体冻伤),左手扳动转换开关到“ 3 ”号位置(喷射顺序为 3 、 2 、 1 ),打开保险机,将喷枪对准火源,扣扳机,干粉即可喷出。如喷完一瓶干粉末能将火扑灭,可将转换开关拨到 2 号或 1 号的位置,连续喷射,直到射完为止。
