The primary tank contained a solution of sodium bicarbonate in h2o, although the internal container (to some degree much larger than the equivalent in a soda-acid unit) contained an answer of aluminium sulphate. When the methods have been blended, normally by inverting the unit, the two liquids reacted to produce a frothy foam, and carbon dioxide gas. The fuel expelled the foam in the form of a jet. Whilst liquorice-root extracts and equivalent compounds were being applied as additives (stabilizing the foam by reinforcing the bubble-walls), there was no "foam compound" in these units.

As the methanol burns off, a glassy coating of boric oxide is left about the floor with the metallic, developing an air-excluding crust. These extinguishers ended up produced by the Ansul Chemical Co. using TMB agent produced through the Callery Chemical Company, and have been modified 2.5-gallon h2o extinguishers (Ansul applied re-branded Elkhart extinguishers at enough time), having a variable-stream nozzle that would supply a straight stream or spray for the squeeze of the lever.
