How do these work? I 've looked in the dictionary and found that they turn fats into soaps. So what goes on? Laymans terms please i'm not a chemist.

it's the hydolysis of fatty ester from triglyerides in basic (meaning Alkali) conditions which forms soap.
Basically a wet chemical fire extighuisher works by converting the burning fat/oil into an non-combustable soap. The reaction needs heat and fatty esters which is what you have in that type of fire. This also cools the fire because the reaction produces steam
Is that any help

Soap has been made from boiling up animal fat or vegetable oil with an alkali since pre-historic times. The main source of alkali was wood ash - potash.
