Portable method of use: can carry the lifting ring on the upper part of the cylinder body, quickly rush to the fire. At this time, attention should be paid to not make the fire extinguisher tilt too much, but not horizontally or upside down, so as not to mix the two agents and spray out in advance. When the distance from the ignition point is about 10 meters, the cylinder can be turned upside down. One hand holds the lifting ring, the other hand holds the bottom ring of the cylinder, and the jet is aimed at the combustion object. When extinguishing flammable liquid fire, if there is a flowing burning, the foam is sprayed from far to near, so that the foam is completely covered on the burning liquid surface; If burning in the container, the foam should be shot towards the inner wall of the container, so that the foam flows along the inner wall and gradually covers the burning liquid level. Do not direct injection at the liquid surface, so as to avoid the impact of the jet, but the burning liquid will be washed away or out of the container, to expand the combustion range. When fighting a solid fire, the jet should be directed at the fiercest burning place. When extinguishing the fire, with the shortening of the effective spraying distance, the user should gradually move closer to the burning area, and always spray the foam on the burner until it is extinguished. When in use, the fire extinguisher should always be upside down, otherwise it will interrupt the injection.
