62. When using dry powder fire extinguisher to put out scattered liquid fire, it should spray from the side of the flame to the root of the flame, spray from near to far, left and right, and push quickly until the flame is extinguished.
7When the flame is driven out of the container during use, it should move forward quickly to put out all the remaining fires. When extinguishing fire, be careful not to spray each nozzle directly at the liquid surface to prevent the impact of dry powder air flow from splashing oil, resulting in continuous expansion of the fire and difficulty in extinguishing the fire.
8When fighting solid material fire, the nozzle of the fire extinguisher should be aimed at the place where the burning is intense, and the dry powder extinguishing agent should be evenly sprayed on the surface of the burning material as much as possible until the fire is extinguished.
9In the process of use, the fire extinguisher shall not be used horizontally or upside down, otherwise powder cannot be sprayed; At the same time, attention should be paid to the prevention of re-ignition after the fire extinguishing of the dry powder fire extinguisher, because the cooling system of the dry powder fire extinguisher has a weak effect, so it is easy to re-ignite after the fire extinguishing.
