How To Use A Portable Foam Fire Extinguisher

You can carry the lifting ring on the upper part of the barrel and quickly rush to the fire. At this time, care should be taken not to tilt the fire extinguisher too much, let alone take it horizontally or upside down, so as to avoid the two agents being mixed and sprayed out in advance. When about 10 meters away from the ignition point, the cylinder can be turned upside down, holding the lifting ring with one hand and holding the bottom ring of the cylinder with the other hand to aim the jet at the burning material. When fighting a combustible liquid fire, if it has been burned in a flowing form, the foam is sprayed from far and near so that the foam completely covers the surface of the combustion liquid; If 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 and gradually covers the fire liquid surface. Do not spray directly at the liquid level, so as not to disperse or flush out the burning liquid out of the container due to the impact of the jet, expanding the combustion range. When fighting a solid fire, the jet should be directed at the place where the burning is most violent. When extinguishing the fire, as the effective spray distance is shortened, the user should gradually approach the combustion area and always spray foam on the burning material until extinguished. When in use, the fire extinguisher should always be kept upside down, otherwise the spray will be interrupted.
