It is suitable for fighting general Class B fires, such as oil and grease fires, and also suitable for Class A fires, but it cannot fight water-soluble flammable and combustible liquids, such as alcohol, ester, ether, ketone and other substances in Class B fires; It is also impossible to put out live equipment and class C and D fires.

Usage: You can carry the lifting ring on the top of the bucket and go to the fire quickly. At this time, care should be taken not to tilt the fire extinguisher excessively, nor to hold it horizontally or upside down, so as to avoid mixing the two chemicals and spraying it in advance.

When the distance from the ignition point is about 10 meter, the cylinder can be turned upside down, with one hand holding the bail tightly and the other hand holding the cylinder bottom ring, aiming the jet at the combustion products. When putting out flammable liquid fire, if it is already flowing and burning, spray foam from far and near to make the foam completely cover the burning liquid surface;

If burning in a container, the foam should be shot at the inner wall of the container, so that the foam can flow along the inner wall and gradually cover the fire surface. It is strictly forbidden to spray directly on the liquid surface, so as to avoid the burning liquid from being scattered or rushing out of the container due to the impact of the jet, and expand the combustion range. When putting out the fire of solid matter, the jet should be aimed at the place where the fire burns most violently. When putting out a fire, with the shortening of the effective spraying distance, users should gradually approach the burning area and always spray foam on the burning object until it is extinguished. When in use, the fire extinguisher should always be turned upside down, otherwise the spraying will be interrupted. ?

Usage: When using, it is usually operated by two people. First push and pull the fire extinguisher to the fire point quickly, and stop at a place about 10 meters away from the fire point. After one person applies the spray hose, hold the spray gun tightly with both hands and aim at the burning place.

The other is to turn the handwheel counterclockwise, so that the screw rises to the highest position, so that the bottle cap is completely opened, and then pour the steel bottle backwards, so that the pull rod touches the ground, rotate the valve handle 90 degrees, and spray foam to extinguish the fire. If the valve is installed at the spray gun, the person in charge of operating the spray gun will open the valve.
