The ABC multipurpose fire extinguisher is the most common fire extinguisher and serves as a great “all purpose” fire extinguisher for common areas and paths of egress within your facility.
ABC extinguishers are effective against Class A, B and C fires, and are required by most fire codes.
The agent within an ABC fire extinguisher is comprised mainly of mono-ammonium phosphate and ammonium sulphate which acts like a heat seeking missile when introduced onto a heat source. It attaches itself to the material that is heated and smothers the fire until it is suppressed.
It prevents the chemical reactions involving heat, fuel, and oxygen (combustion), thus extinguishing the fire.
They are the best overall extinguisher for most common home and workplace environments.
