what is Foam fire extinguishers

Answer 1

Answer:

An alternative to water and dry chemical extinguishers for Class A and B fires is a foam extinguisher. Foam agents work well on combustible materials like wood, paper, and cloth as well as flammable oils, diesel fuel, and alcohols to name a few. They are non-toxic and extinguish the fire by forming a blanket on the surface of the burning hazard, which both cools and smothers the fire by removing the oxygen. Removing the heat and oxygen from the fire also helps to prevent re-ignition.

Foam extinguishers can be used where flammable liquids are transported, processed, stored or used as an energy source.
