Class B fire extinguishers are effective against flammable liquid-form fires. Examples of which are cooking oils, gasoline, kerosene and the like. There are two commonly used effective fire-fighting chemicals used in these types of fire namely monoammonium phosphate and sodium bicarbonate. The monoammonium phosphate can effectively smother the fire from these liquid combustibles while the sodium bicarbonate induces a chemical reaction to extinguish the fire.
