How to use a portable foam extinguisher:
When in use, you can quickly rush to the fire with your hands or shoulders. When it is about 6 meters away from the burning material, pull out the safety pin, and hold the opening handle in one hand and the spray gun in the other.
Squeeze the opening handle hard, open the seal or puncture the seal of the gas cylinder, and the air foam can be ejected from the nozzle of the spray gun. The fire extinguishing method is the same as that of portable chemical foam extinguisher.
However, when using the air foam extinguisher, the fire extinguisher should always be in an upright position, and it should not be used upside down or horizontally, otherwise the spraying will be interrupted.
