灭火器灭火时的喷射口应该对准火焰哪里？
川消小编给您讲，实际上用灭火器灭火时，灭火器的喷射口应该对准火焰的根部。下面我们从两方面内容了解起来。
Where should the nozzle of the fire extinguisher aim at the fire? Chuan Xiaobian told you that when using a fire extinguisher to extinguish a fire, the nozzle of the fire extinguisher should aim at the root of the flame. Now let's learn from two aspects.
干粉灭火器：
Dry powder fire extinguisher:
灭火时，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。
When putting out a fire, you can quickly rush to the fire site with a portable or shoulder mounted extinguisher, and put down the extinguisher about 5 meters away from the burning place. If it is outdoors, spray in the upwind direction. If the dry powder extinguisher used is of externally mounted pressure storage type, the operator shall hold the spray gun with one hand and lift the opening bail on the gas cylinder with the other hand.
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。
If the opening of the gas cylinder is handwheel type, unscrew it counterclockwise, rotate it to the high position, and then lift the fire extinguisher. When the dry powder is sprayed, it should be aimed at the root of the flame quickly.
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。
If the dry powder extinguisher used is of built-in gas cylinder or pressure storage type, the operator should first pull out the safety pin on the opening handle, and then hold the nozzle at the front of the spray hose, with the other hand, press the opening handle down, and open the extinguisher to extinguish the fire. When using a fire extinguisher with a spray hose or a pressure storage fire extinguisher, always press the handle down with one hand and do not release it, otherwise the spraying will be interrupted.
二氧化碳灭火器：
Carbon dioxide extinguisher:
灭火时只要将灭火器提到或扛到火场，在距燃烧物5米左右，拔出灭火器保险销，一手握住喇叭筒根部的手柄，另一只手紧握启闭阀的压把。对没有喷射软管的二氧化碳灭火器，应把喇叭筒往上板70-90度。
When putting out a fire, just lift or carry the extinguisher to the fire site, pull out the safety pin of the extinguisher at a distance of about 5 meters from the combustor, and hold the handle at the bottom of the horn with one hand and the handle of the on-off valve with the other hand. For carbon dioxide extinguishers without jet hoses, the horn shall be 70-90 degrees higher than the upper plate.
使用时，不能直接用手抓住喇叭筒外壁或金属连线管，防止手被冻伤。灭火时，当可燃液体呈流淌状燃烧时，使用者将二氧化碳灭火剂的喷流由近而远向火焰喷射。
When using, do not directly grasp the outer wall of the horn or the metal connecting pipe with your hands to prevent your hands from being frostbitten. When putting out a fire, when the flammable liquid burns in flowing form, the user sprays the carbon dioxide extinguishing agent from near to far to the flame.
如果可燃液体在容器内燃烧时，使用者应将喇叭筒提起。从容器的一侧上部向燃烧的容器中喷射。但不能将二氧化碳射流直接冲击可燃液面，以防止将可燃液体冲出容器而扩大火势，造成灭火困难。
If the flammable liquid burns in the container, the user should lift the horn. Spray from the upper side of the container into the burning container. However, it is not allowed to directly impact the flammable liquid surface with the carbon dioxide jet, so as to prevent the flammable liquid from rushing out of the container and expanding the fire, causing difficulty in extinguishing.
The above is the relevant answer to the question. If you are interested in understanding or need to buy fire-fighting equipment such as fire extinguishers, please come to our website http://www.cx-fire.com Consult.
