Odorizers are used in carbon dioxide fire extinguisher systems, the odorizer assembly injects wintergreen oil into the carbon dioxide stream when the agent is discharged. Approximately 50 cc of wintergreen oil contained within a frangible glass cartridge is mounted within a protective housing attached to the discharge piping in such a manner as ...
An anecdotal report of a carbon dioxide fire extinguisher was published in Scientific American in 1887 which describes the case of a basement fire at a Louisville, Kentucky pharmacy which melted a lead pipe charge with CO 2 (called carbonic acid gas at the time) intended for a soda fountain which immediately extinguished the flames thus saving ...
Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers.

Understanding the cause is essential so that the correct fire extinguisher is used; if the wrong extinguisher is used, it can either make the fire worse or fail to control it. For example, using a type A, B, C fire extinguisher on a chemical fire will do the opposite of what the extinguisher is supposed to do and can cause an explosion.
Classes of fire extinguisher and corresponding type of fire they extinguish. Claw tool Early striking and prying tool. Closed-circuit SCBA See SCBA. Closet hook Pike pole under 5 ft long Closet ladder See Attic ladder. CO 2 extinguisher Fire extinguisher that releases carbon dioxide gas to displace oxygen to smother and cool a fire, such as a ...
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
