Scope of application: carbon dioxide fire extinguisher is mainly used to put out valuable equipment, archives, instruments, electrical equipment below 600 volts and oil fire. When in use, the fire extinguisher should first be brought to the fire site, put down the fire extinguisher, pull out the safety pin, hold the handle at the root of the horn with one hand, the other hand firmly grasp the pressure handle of the opening and closing valve. For carbon dioxide fire extinguishers without spray hoses, the horn should be turned up 70-90 degrees. When using, do not grasp the outer wall of the horn or the metal connecting pipe directly with your hand to prevent frostbite. In the use of carbon dioxide fire extinguishers, used outdoors, should choose the direction of the wind injection; In the narrow space used indoors, the operator should leave quickly after extinguishing the fire to prevent suffocation.
Usage: When putting out the fire, just lift or carry the fire extinguisher to the fire site, about 5 meters away from the combustion object, pull out the safety pin of the fire extinguisher, hold the handle at the root of the horn with one hand, and the pressure handle of the opening and closing valve with the other hand. For carbon dioxide fire extinguishers without spray hoses, the horn should be positioned 70-90 degrees to the upper plate. When using, do not grasp the outer wall of the horn or the metal tube directly with your hand to prevent frostbite. When extinguishing the fire, when the flammable liquid is burning in a flowing manner, the user will spray the carbon dioxide extinguishing agent jet from near to far towards the flame. If flammable liquid is burning in the container, the user should lift the horn. Spray from the upper side of the container into the burning container. However, it is not possible to directly impact the carbon dioxide jet on the flammable liquid level, so as to prevent the flammable liquid from rushing out of the container and expanding the fire, causing difficulty in extinguishing the fire.
Note: When using carbon dioxide fire extinguishers, those used outdoors should choose to spray in the upwind direction and put their hands on the wooden handle of the cylinder to prevent frostbite. In the narrow space used indoors, the operator should leave quickly after extinguishing the fire to prevent suffocation. [1]
Others: The wheeled carbon dioxide extinguisher is generally operated by two people. When in use, two people push or pull the extinguisher together to the burning place and stop about 10 meters away from the combustion object. One person quickly takes off the horn and expands the spray hose, then holds the handle at the root of the horn, and the other person quickly rotates the handwheel in the counterclockwise direction and opens it to the maximum position. The fire extinguishing method is the same as the portable method.
