Hand-held method of use: You can carry the lifting ring on the upper part of the barrel 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 prevent the two agents from mixing and spraying out in advance. When the distance from the ignition point is about 10 meters, the cylinder can be turned upside down, holding the lifting ring tightly with one hand, and holding the bottom ring of the cylinder with the other hand, aiming the jet at the burning material. When fighting a flammable liquid fire, if it burns in a flowing state, spray the foam from far to near to make the foam completely cover the surface of the burning liquid; if it burns in the container, shoot the foam towards the inner wall of the container to make the foam Flowing along the inner wall, gradually covering the fire surface. Do not directly aim at the liquid surface to spray, so as to avoid the impact of the jet, the burning liquid will be scattered or flushed out of the container to expand the burning range. When fighting a solid material fire, the jet should be aimed at the most violent burning place. With the shortening of the effective spraying distance when extinguishing the fire, the user should gradually approach the burning area and always spray foam on the burning material until it is extinguished. When in use, the fire extinguisher should always be kept upside down, otherwise the spray will be interrupted.
Portable foam fire extinguishers should be stored in a dry, cool, well-ventilated place that is easy to access, and should not be near high temperature or places that may be exposed to the sun to prevent carbonic acid decomposition and failure; antifreeze measures should be taken in winter to prevent freezing; and should be frequently wiped Remove dust and dredge the nozzle to keep it unobstructed.
