What are the daily inspection items of carbon dioxide fire extinguishers?
A carbon dioxide fire extinguisher uses a liquid carbon dioxide that is filled to fire a fire extinguisher. It is composed of cylinder, bottle valve, injection system and so on. (1) portable carbon dioxide extinguisher. The total weight is less than or equal to 28KG, and its specifications are 2kg, 3kg, 5kg, 7kg four; (2) cart type carbon dioxide extinguisher. The total weight is greater than 28KG, and its specifications are 20kg, 25kg, two kinds. Carbon dioxide fire extinguisher is suitable for fighting all kinds of flammable liquid and combustible gas. And the fire of live equipment and precision electronic instruments and valuable equipment. But it should not be used outdoors when the wind blows, and in the narrow and confined space after use, it is necessary to timely ventilation or evacuation of the scene, in case of suffocation.
Carbon dioxide fire extinguisher: carbon dioxide extinguishing agent is a fire extinguishing agent with a history of more than 100 years. It is cheap, easy to obtain and easy to prepare. It mainly relies on smothering action and partial cooling action to extinguish the fire. Carbon dioxide has a higher density, about 1.5 times that of the air. At normal pressure, liquid carbon dioxide vaporizes immediately, and liquid carbon dioxide, typically 1kg, produces about 0.5 cubic meters of gas. Therefore, when the fire, carbon dioxide gas can eliminate the air and surround the surface of the object or the distribution of combustion in a relatively closed space, reducing the fuel around or in the protection room oxygen concentration, produce suffocation and fire. In addition, when carbon dioxide is ejected from the storage vessel, it is rapidly vaporized into a gas by the liquid, which absorbs some of the heat from the surrounding and acts as a cooling agent.
There is no pressure gauge in the CO2 fire extinguisher and it is weighed in actual operation. The quality of the empty bottle is written on the bottle so that it can check the net quality of the carbon dioxide inside.
