Suitable for general Class B fires, such as oil products, oils and other fires, but also
Hand-held foam fire extinguisher
Hand-held foam fire extinguisher
Suitable for Class A fires, but can not fight against water soluble flammable and flammable liquid fires in Class B fires, such as alcohol, Ester, ether, ketone and other substances fire; Nor can it save live equipment and Class C and Class D fires. Can carry the upper part of the body ring, quickly to the fire.
Care should be taken not to tilt the fire extinguisher too much at this time, not to cross or reverse, so as not to mix the two agents and spray in advance.
When about 10 meters away from the ignition point, the cylinder can be reversed, one hand holds the hoist ring, and the other hand holds the bottom ring of the cylinder to align the jet with the combustion. When fighting a flammable liquid fire, if it has been flowing, the foam is sprayed from near to far so that the foam is completely covered on the combustion liquid surface; If burned in the container, the foam should be fired on the inner wall of the container so that the foam flows along the inner wall and gradually covers the fire surface. Avoid direct injection of liquid surface to avoid the impact of the jet, but will burn the liquid or out of the container to expand the combustion range. When fighting a solid fire, the jet should be directed at the most violent place to burn. When extinguishing the fire, with the reduction of the effective injection distance, the user should gradually approach the burning area and always spray the foam on the burning material until it is extinguished. When used, the fire extinguisher should always be in an inverted state, otherwise the jet will be interrupted.
