Cart-type carbon dioxide fire extinguishers are mainly used to save valuable equipment,booksarchives, instrumentation,600below voltschargedelectrical equipment andGeneral flammable liquid fires.Extinguishing agentCarbon dioxide is an inert gas, which is neither combustible nor combustible.2Carbon dioxide has a higher density,Has the effect of cooling and isolating air,When extinguishing a fire, carbon dioxide gas can exclude air and surround the surface of the burning object or distribute in a relatively closed space, reduce the oxygen concentration around the combustibles or in the protective space, and cause suffocation to extinguish the fire. Carbon dioxide gas is released from the storage container When it is sprayed out, it will quickly vaporize from liquid to gas, absorb part of the heat from the surrounding, and play a role.fastcooling effect.

Cart-type carbon dioxide fire extinguishers are generally operated by two people. When in use, the two people push or pull the fire extinguisher to the burning place.10After stopping for about 1 meter, one person quickly removes the horn and unfolds the spray hose, then holds the handle at the root of the horn, and the other quickly turns the handwheel in a clockwise direction to the maximum position. The carbon dioxide jet cannot be directly Spray on the surface of the flammable liquid to prevent the flammable liquid from flushing out of the container and expanding the fire, making it difficult to extinguish the fire.

2.When using in a small indoor space, the operator should leave quickly after extinguishing the fire to prevent suffocation;
3.When using, try to prevent the skin from directly contacting the spray barrel and spray pipe to cause frostbite;
4.When fighting an electrical fire, if the voltage exceeds600volts, remember to cut off the power first and then put out the fire;
