Carbon dioxide extinguishers provide the power to respond quickly and effectively to protect against Class B (flammable liquids and gases) and Class C (energized electrical equipment) fires. These extinguishers are well suited for indoor use in furnace rooms, printing presses, pump rooms, electrical power panels, and laboratories where winds and drafts do not affect discharge.
When using a co2 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. If you use it indoors in a small space, the operator should leave quickly after extinguishing the fire to prevent suffocation. Push the cart type co2 fire extinguisher is generally operated by two people, use two people together to push or pull the fire extinguisher to the burning place, stop at about 10 meters from the burning object, one person quickly removes the horn barrel and expand the spray hose, hold the handle at the root of the horn barrel, the other person quickly rotates the handwheel in the counterclockwise direction, and open to the maximum position.
