The use of portable foam fire extinguisher

In the event of a fire, the operator can carry the upper ring of the cylinder and quickly run to the fire. At this time should be careful not to make the fire extinguisher too tilted, not to mention the horizontal take or upside down, so as not to mix the two agents and spray out in advance. When the fire is about 10 meters away, you can turn the barrel upside down, one hand holding the ring, the other hand holding the bottom ring of the barrel, the jet stream will be aimed at the burning material. In fighting flammable liquid fires, such as a burning liquid that has been flowing burning, the foam will be sprayed from a distance so that the foam is completely covered in the burning liquid surface; such as burning in the container, the foam should be shot to the inner wall of the container, so that the foam flows along the inner wall, gradually covering the surface of the fire. Do not spray directly to the liquid surface, so as not to be due to the impact of the jet, but will be scattered or flushed out of the burning liquid container, expanding the scope of combustion. In fighting solid material fires, the jet should be aimed at the most violent combustion. When extinguishing a fire, as the effective spraying distance shortens, the user should gradually approach the burning area and always spray the foam on the burning material until extinguished. When using, the extinguisher should always be kept upside down, otherwise, the spray will be interrupted.

Portable foam fire extinguishers should be stored in a dry, cool, ventilated, and easy to access place, not near the high temperature or may be exposed to the sun to prevent carbonic acid decomposition and failure. Winter to take anti-freeze measures to prevent freezing, and should often wipe the dust, unclog the nozzle, so that it is kept smooth.

When used, generally by two people to operate, the first fire extinguisher will be quickly pushed and pulled to the fire, stop at about 10 meters from the point of fire, by one person after the application of the spray hose, hands hold the gun and aimed at the burning; the other is the first counterclockwise rotation of the handwheel, the screw up to the highest position so that the cap open enough, and then the barrel backward, so that the lever touches the ground, and the valve handle rotated 90 degrees, you can spray foam to extinguish the fire.
