How Does A Dry Chemical Fire Extinguisher Work?
All fire extinguishers work by removing one or more of the 3 key elements that are required for a fire to flourish.
ABE fire extinguishers are filled with the chemical powder, monoammonium phosphate, which acts as an extinguishing agent. This chemical spreads easily and melts over the flames to cover the fire in the case of class A and E fires, and thus puts it out.
With class B fires, the powder smothers the base of the fire and blocks the vapor from escaping, which puts out the fire immediately.
BE fire extinguishers contain a different type of dry chemical powder which doesn’t melt over the flames. Thus, it cannot be used to put out class A fires.
