How to use a portable foam fire extinguisher

You can carry the lifting ring on the upper part of the cylinder and rush to the fire scene quickly. At this time, care should be taken not to tilt the Fire Extinguisher excessively, nor to hold it horizontally or upside down, to prevent the two agents from mixing and spraying out in advance. When you are about 10 meters away from the ignition point, you can turn the cylinder upside down, hold the lifting ring tightly with one hand, hold the bottom ring of the cylinder with the other hand, and aim the jet at the burning object. When extinguishing a flammable liquid fire, if it is burning in a flowing state, spray the foam from far to near so that the foam completely covers the burning liquid surface; if it burns in a container, shoot the foam toward the inner wall of the container so that the foam It flows along the inner wall and gradually covers the fire liquid surface. Do not spray directly at the liquid surface to avoid the impact of the jet from scattering or flushing the burning liquid out of the container and expanding the combustion range. When fighting a solid material fire, the jet should be aimed at the most violent burning point. When extinguishing a fire, as the effective spray distance shortens, the user 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 kept upside down, otherwise the spray will be interrupted.
