How to use carbon dioxide fire extinguishers and precautions
In use, the fire extinguisher should first be referred to the fire location, put down the fire extinguisher, pull out the insurance pin, one hand holding the handle of the horn at the root, and the other hand gripping the pressure of the on-off valve. For carbon dioxide fire extinguishers without jet hose, pull the horn up 70 to 90 degrees. When using, you can't directly grab the outer wall of the horn or the metal connecting pipe to prevent the hands from frostbite. When using a carbon dioxide fire extinguisher, it should be chosen to spray in the upwind direction when it is used outdoors; if it is used in a narrow space indoors, the operator should leave immediately after the fire to prevent suffocation.
Instructions
When extinguishing a fire extinguisher, as long as the fire extinguisher is mentioned or dumped into the fire, remove the fire extinguisher safety pin approximately 5 meters from the burning object, hold the handle of the horn at the root with one hand, and hold the pressure knob of the on-off valve with the other hand. For CO2 fire extinguishers without jet hose, the horn should be 70-90 degrees upwards. When using, do not directly grasp the outer wall of the horn or metal connecting pipe to prevent hands from being frosted. When the fire is extinguished, when the flammable liquid burns like a drool, the user sprays the jet of carbon dioxide extinguishing agent from near to far to the flame. If the flammable liquid is burning in the container, the user should lift the horn. Spray from the upper side of the container to the burning container. However, it is not possible to directly impact the flammable liquid surface with the carbon dioxide jet so as to prevent the flammable liquid from being flushed out of the container to expand the fire and cause difficulty in extinguishing the fire.
Precautions
When using a carbon dioxide fire extinguisher, if it is used outdoors, it should be sprayed in the upwind direction, and the hand should be placed on the wooden handle of the cylinder to prevent frostbite. When used in a narrow space in a room, the operator should promptly leave after the fire to prevent suffocation.
Others: The cart type carbon dioxide fire extinguisher is generally operated by two people. When the two are used, they push or pull the fire extinguisher together to the burning place and stop at about 10 meters from the burning object. After one person quickly removes the horn and starts spraying the hose, Hold the handle of the horn at the root, another person quickly rotates the handwheel counterclockwise and opens to the maximum position. The fire extinguishing method is the same as the hand-held method.
