New Extinguisher Chemical

The U. S. Army has announced development of a new chemical compound which is said to be twice as effective in extinguishing liquid fuel and electrical fires as other agents. Monobromotrifluromethane is mixed with helium or nitrogen which creates a combustion-free atmosphere when applied to dangerous fires.

New Extinguisher Chemical

A new boron chemical compound called “TMB” has been introduced for use on fires involving metals such as magnesium, titanium and zirconium. A colorless liquid containing a high percentage of trimethoxyboromine, it is said to be effective on such fires and also useful in controlling the burning of sodium and sodium-potassium alloy.

The “TMB” when applied to a metal fire burns to give a coating of molten boric oxide over the metal, which excludes the air and extinguishes the fire. By proper application, some metals which are exceedingly flammable under certain conditions can be controlled.
