What are the daily inspection items of carbon dioxide fire extinguishers?
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.
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.
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.
