Co2 fire extinguisher9/7/2023 ![]() ![]() Then direct the extinguisher at the near edge of the flames and swept from side to side toward the back of the fire or toward the center of the area that is burning (it is important not to touch the discharge horn, because it may become very cold during discharge).įor fires involving electrical equipment, the extinguisher should be aimed at he base of the fire. The ring pin normally keeps the operating lever locked and prevents the extinguisher from discharging accidentally. When use a CO2 fire extinguisher, the first step is to place it in a upright position using its carrying handle, hold the carrying handle in one hand, and pull out the ring pin with the other hand. If it's diluted enough, people in the space can begin to suffocate. Confined spaces: when used in confined areas, CO2 dilutes the oxygen in the air.Weather: CO2 does not perform at temperatures below -18° or in windy or drafty conditions, because it dissipates before it reaches the fire.2 Range: CO2 extinguishers have a short discharge range. ![]() This means that the containers in which it is stored is relatively large and heavy. Weight: to store CO2 as a liquid, it must be pressurised to over 50 BAR.Co2 also has several limitations and disadvantages: In this case, when the pressure is too high, the burst disc ( It's like a fuse for pressure) blows and it allows the fire extinguisher depressurization.ĬO2 is approved for use on B class fires, but it's not suitable for A class fires ( flammable solids, flammable gasses or cooking fat ). Each differnt type of extinguisher agents has a corresponding colour making identification easier for the user, Often CO2 type has the grey one, but it is not obligatory.ĬO2 fire extinguisher has a safety valve that operates when the pressure inside the tank pass 170 bar. Generally fire extinguishers have a colored band covering part of the surface relating to the extinguisher's contents. Its label must show: testing pressure, year of construction, identification number,tare, possible testing dates, maker's name. The body is entire without weld joints, and it can be made in steel or light alloy.įire extinguishers manufactured before the PED legisltion are obliged to respect the time limits according to the legislation on the subject of molten and pressurized gases. The body of these extinguishers is generally smaller and slightly than the taller and slender body of the all-purpose extinguishers. Today carbon dioxide is the most commonly used “inert” gas extinguishing agent, It means that carbon dioxide is suitable for use on fires where electrical systems may still be under power. If applied correctly, it reduces the oxygen content in the air around the fuel to below that required for combustion to take place. The main way CO” extinguishes fire is by smothering. This type of extinguisher is higly pressurized with carbon dioxide, which is a non-flammable inert gas ( a pressure at about 55/60 bar at 20° ). This extinguishing agent is clean, non-corrosive and leaves no residues so it's no damaging to electrical equipment and machinery. CO2 FIRE EXTINGUISHERSĬO2 fire extinguisher is used for extinguishing B class fires ( flammable liquids). In the last years, with the coming of globalization, the market is evolving, therefore, the Emme company, drawing on its own experience and its high quality standard of production, has invested in new products addressed to European market with over 100 certifications of new fire extinguishers. Emme Antincendio works in Italy and abroad by virtue of its fire extinguishers wide range: Co2, Dry Powder And Foam Fire Extinguishers , with characteristics respecting the needs too of cold in the North of Italy/Europe ( Class F foam fire extinguishers validations and certifications up to -30 C°). ![]()
