When using, the handle or shoulder of the fire extinguisher should be close to the fire. Put down the fire extinguisher about 5 meters away from the burning place, first pull out the safety pin, hold the opening handle in one hand and the nozzle at the front end of the injection hose in the other. If the fire extinguisher has no spray hose, you can hold the opening handle with one hand and the bottom ring part at the bottom of the fire extinguisher with the other hand.
Aim the nozzle at the burning place, and firmly hold the opening knob to make the fire extinguisher spray. When the rescued combustible liquid is flowing and burning, the user should aim at the root of the flame from near to far and from left to right and push it forward quickly until the flame is completely extinguished.
