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 ...
The different types of fire extinguishers include CO 2 fire extinguishers, type A, B, or C carbon dioxide fire extinguishers, dry chemical powder extinguishers, and water-based fire extinguishers. [3] Carbon dioxide is released from CO 2 extinguishers to smother the fire and prevent the fire from getting oxygen, which will suppress the fire. [4]
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.
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.

By dilution: Some retardants release water and/or carbon dioxide while burning. This may dilute the radicals in the flame enough for it to go out. Commonly used fire retardant additives include mixtures of huntite and hydromagnesite, aluminium hydroxide, and magnesium hydroxide.
