On Class A fires the particles fuse and swell to form a barrier which excludes oxygen and prevents re-ignition.
On Class B fires the powder interferes with the chemical reactions, thus the flame ceases to exist.
The powder is nonconductive.
ABC 40 powder will extinguish Class A (carbonaceous) fires,
Class B (flammable liquid) fires and Class C (flammable gas) fires.
