Dry Powder extinguishers put out fire by coating the fuel with a thin layer of dust, 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 fire.
How dry powder fire extinguishers work: Dry powder fire extinguishers smother fires by forming a barrier between the fuel and the source of oxygen. As they do not cool the fire, there is a small risk of re-ignition. NaOH+AlCl3+2NaHCO3====Al(OH)3↓+2CO2↑+3NaCl
