When TMB contacts the fire, the methanol ignites and burns which has a greenish flame mainly because of the boron. As being the methanol burns off, a glassy coating of boric oxide is still left about the surface area in the metal, making an air-excluding crust. These extinguishers were being produced by the Ansul Chemical Co. making use of TMB agent produced through the Callery Chemical Business, and had been modified 2.five-gallon h2o extinguishers (Ansul utilized re-branded Elkhart extinguishers at the time), which has a variable-stream nozzle that could supply a straight stream or spray within the squeeze of a lever. A six-inch fluorescent orange band Along with the letters "TMB" stenciled in black recognized TMB from other extinguishers.
