5KG CO2 Fire Extinguisher
Carbon dioxide (CO2) fire extinguishers cease fire by removing the oxygen of the fire triangle. They are usually used for Class B and electrical fires and are ineffective in the case of Class A fires. As 5KG CO2 fire extinguishers are common firefighting tools, they are found almost everywhere. Unlike the foam type and powder type extinguispanshers, they do not leave any irritating foam or residue after extinguishing fire.
Generally, 5KG CO2 fire extinguishers are red in color and the body is made of steel. Also, there must be a black band in the body which includes the information of the extinguishers. They are made in a way to provide easy, safe maintenance. Horn, operating lever or handle, safety pin, valve etc. are an essential part of a 5KG CO2 fire extinguisher.
Things to Note
CO2 fire extinguishers can create ice cold temperatures which can freeze the horn and cause injury to the person operating it. Therefore, Frost free horns are designed in a way that can withstand the freezing temperature and allows the user to have direct contact with the horn.
Usually, the Pressure gauge is not included in these extinguishers. The only way to check the functionality is by measuring the gross weight of the extinguishers. In most of these extinguishers, wall mount is included and for easy identification during a fire, one should purchase fire extinguisher signage.
The CO2 gas inside the extinguisher is extracted from the atmosphere and kept under enormous pressure (50 to 60 bars). They become liquid at that pressure. Once the lever is pressed, the liquefied CO2 diffuses through the horns and take away the oxygen from the fire triangle. While using the CO2 extinguisher, it is better to maintain 3 feet distance from the fire.
Benefits of Using Carbon Dioxide Fire Extinguishers
There are some benefits of using carbon dioxide fire extinguishers. One of them is that these extinguishers do not leave any residue. Also, CO2 fire extinguishers are easy to operate. The swiveling horn gives better flexibility to direct the gas. CO2 fire extinguishers come in different sizes which enables the user to buy according to their needs. As these extinguishers are used for fighting Class B and electrical fires, they are found in a majority of places. Hence, they provide better protection against a common class of fires.
