Using method of carbon dioxide fire extinguisher

Fire extinguishers as long as the fire extinguisher mentioned or carried to the scene, in the distance of 5 meters from the burning, pull out the fire extinguisher insurance pin, one hand hold the horn of the root of the handle, and the other holding the pressure of the headstock valve. For a carbon dioxide fire extinguisher without a jet hose, the horn should be 70-90 degrees above the plate. When used, it is not possible to grasp the outer wall of the horn tube or the metal connecting tube directly with the hand to prevent frostbite. When the flammable liquid is in a flow-like combustion, the user will spray the carbon dioxide extinguishing agent from near to the flame. If the flammable liquid is burned in the container, the user shall lift the trumpet. Spray from the upper side of the container to the burning vessel. However, it is not possible to direct the carbon dioxide jets to the combustible liquid surface, so as to prevent the fire from being flushed out of the container and to cause a difficulty in extinguishing.
