In 1902, a method of extinguishing flammable liquid fires by blanketing them with foam was introduced by Russian engineer and chemist Aleksandr Loran. Loran was a teacher in a school in Baku , the center of the Russian oil industry at that time.
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the combustion. Fire-fighting foam was invented by the Russian

What is the history of fire fighting foam?
History of fire-fighting foams. In the mid-1960s, the US Navy developed aqueous film-forming foam (AFFF). This synthetic foam has a low viscosity and spreads rapidly across the surface of most hydrocarbon fuels. A water film forms beneath the foam, which cools the liquid fuel, stopping the formation of flammable vapors.
Why are foam fire extinguishers discharged directly from the unit?
Because of this, the foam was discharged directly from the unit, with no need for an aspirating branchpipe (as in newer mechanical foam types). Special versions were made for rough service, and vehicle mounting, known as apparatus of fire department types.
Why is protein foam used in fire extinguishers?
Its expansion ratio and ease of handling made it popular. Protein foam is easily contaminated by some flammable liquids, so care should be used so that the foam is applied only above the burning liquid. Protein foam has slow knockdown characteristics, but it is economical for post-fire security.
