手提式干粉式灭火器

The portable powder fire extinguisher 

可手提或肩扛灭火器快速奔赴火场，在距燃烧处5米左右，放下灭火器。如在室外，应选择在上风方向喷射。使用的干粉灭火器若是外挂式储压式的，操作者应一手紧握喷枪、另一手提起储气瓶上的开启提环。如果储气瓶的开启是手轮式的，则向逆时针方向旋开，并旋到最高位置，随即提起灭火器。当干粉喷出后，迅速对准火焰的根部扫射。使用的干粉灭火器若是内置式储气瓶的或者是储压式的，操作者应先将开启把上的保险销拔下，然后握住喷射软管前端喷嘴部，另一只手将开启压把压下，打开灭火器进行灭火。有喷射软管的灭火器或储压式灭火器在使用时，一手应始终压下压把，不能放开，否则会中断喷射。

Can hand or shoulder quickly rushed to the fire, fire extinguishers in combustion 5 meters or so, put down the fire extinguisher. As in the outdoor, should choose in the windward direction injection. Use of dry powder fire extinguishers and if the case of reservoir pressure, the operator should hold spray gun, the opposite hand lift air cylinder on the open loop. If the gas bomb open is a hand wheel, then to spin counterclockwise, and back to the highest position, then filed a fire extinguisher. After the dry out, quickly the root of the flames. Use dry chemical fire extinguisher is built-in air cylinder or reservoir pressure, the operator should be pulled open the insurance on the pin, and then hold the injection hose front end of the nozzle, another hand will open, under pressure to open the fire extinguisher to put out the fire. Discharge hose fire extinguisher or reservoir pressure fire extinguisher when use, should always be hand pressed down, can't let go, otherwise you will interrupt injection. 

干粉灭火器扑救可燃、易燃液体火灾时，应对准火焰要部扫射，如果被扑救的液体火灾呈流淌燃烧时，应对准火焰根部由近而远，并左右扫射，直至把火焰全部扑灭。如果可燃液体在容器内燃烧，使用者应对准火焰根部左右晃动扫射，使喷射出的干粉流覆盖整个容器开口表面；当火焰被赶出容器时，使用者仍应继续喷射，直至将火焰全部扑灭。在扑救容器内可燃液体火灾时，应注意不能将喷嘴直接对准液面喷射，防止喷流的冲击力使可燃液体溅出而扩大火势，造成灭火困难。如果当可燃液体在金属容器中燃烧时间过长，容器的壁温已高于扑救可燃液体的自燃点，此时极易造成灭火后再复燃的现象，若与泡沫类灭火器联用，则灭火效果更佳。

Dry powder fire extinguisher saves the flammable and combustible liquid fire, should be to flames shooting, if the fighting and flowing liquid fire is burning, should be the root of flames from near and far, and shooting, until all put out the blaze. If burning combustible liquid in the container, the user should be the root of flames from side to side, causing the ejected powder flow to cover the entire container openings surface; When the fire is out of the container, the user should still continue to spray, until all put out the flame. Container combustible liquid fire in fighting, attention should be paid to the nozzle can not be pointed directly at liquid level jet, and prevent the impact of the jet stream make flammable liquid spatter and expand the fire, fire caused difficulties. If when the flammable liquid in a metal container combustion time is too long, flammable liquid container wall temperature is higher than fighting the self-ignition point, easy to cause fire at this time and then the phenomenon of resurgence, if with foam fire extinguisher combination, the extinguishing effect is better.
