New Extinguisher Chemical

Issue 2 and Volume 110.

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.
