![]() ![]() 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. They are not useful as a method of extinguishing ordinary flammable combustible solids, as the solid will continue to smolder after being extinguished and may reignite once oxygen returns to its immediate atmosphere.Ī dry chemical fire extinguisher can be used to eliminate all of the types of fire that a carbon dioxide extinguisher can, as well as additional fire types such as Class A fires however, a carbon dioxide extinguisher may be better-suited for the elimination of a Class B or C fire, as dry chemical extinguishers release a toxic substance that is easily inhaled if used in an enclosed space without adequate respiratory protection.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°). In this case, a carbon dioxide extinguisher can be used to eliminate the fire by displacing the oxygen that the fire relies upon for fuel.īecause carbon dioxide is a non-conductive material, CO 2 extinguishers are also useful for extinguishing electrical (Class C) fires and were originally developed for this purpose. The reaction may inadvertently cause the flaming liquid to displace or splash, and water may not be able to reduce the heat from the fire to a low-enough temperature to terminate the combustion reaction that keeps the fire burning. The type of fire suppressant that needs to be used to extinguish a particular workplace fire varies depending on the substance that is fueling the fire, as well as the equipment and human safety considerations that exist within the vicinity of the fire.įor instance, traditional water extinguishers are useful for extinguishing ordinary combustion fires (Class A fires) by eliminating the heat necessary for the fire to continue however, they are not effective for situations in which the source of the fire is a liquid (Class B) or gas.
