It is exclusive being an extinguishing agent in which the agent itself is usually a flammable liquid. When TMB contacts the fire, the methanol ignites and burns with a greenish flame due to boron. Since the methanol burns off, a glassy coating of boric oxide is remaining over the area from the steel, developing an air-excluding crust. These extinguishers were created by the Ansul Chemical Co. employing TMB agent produced via the Callery Chemical Enterprise, and ended up modified two.5-gallon water extinguishers (Ansul used re-branded Elkhart extinguishers at enough time), using a variable-stream nozzle that may supply a straight stream or spray in the squeeze of the lever.

Other brokers had been additional to suppress the methanol flare up, like CBM, Halon 2402, and Halon 1211, with diversified accomplishment. Halon 1211 was probably the most profitable, along with the combined TMB pressurized with halon 1211 and nitrogen was termed Boralon and was made use of experimentally by the Los Alamos Countrywide Laboratory to be used on atomic metals, working with sealed cylinder extinguishers created by Metalcraft and Graviner which removed the dampness contamination trouble. TMB/Boralon was abandoned in favor of more flexible agents, while it remains to be pointed out in the majority of US firefighting literature.[39]
