How to Use a Fire Extinguisher to Put Out Fire in Subject 4?

[AdrianaMarie]

When extinguishing a fire, you can quickly rush to the fire scene by carrying the fire extinguisher in hand or on your shoulder, and place it down about 5 meters away from the burning area. Outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher is an external type, the operator should hold the spray gun tightly with one hand and lift the opening ring on the gas storage cylinder with the other hand. Turn it counterclockwise to the highest position, then lift the fire extinguisher. Once the dry powder is ejected, quickly aim at the base of the flame and sweep. If it is a built-in gas storage cylinder, first pull out the safety pin, hold the front nozzle part of the spray hose, then press down the opening lever to activate the fire extinguisher for firefighting. For fire extinguishers with spray hoses or stored-pressure fire extinguishers, one hand should always press down the lever during use and not release it, otherwise the spray will be interrupted.
