Abstract
A fire control composition in particulate form and containing no water, which is particularly effective for fighting metal fires, i.e., Class D fires, and which comprises particles of crushed glass bearing a hydrophobic coating thereon so that agglomeration of the fire control composition due to adsorption of moisture during storage and use is substantially prevented and so that when applied to fire, the fire control composition forms a blanket over the fire which deprives the fire of oxygen and thereby smothers it. The composition additionally contains one or more particulate adjuvants selected from salts and/or spherulized vitreous beads, which adjuvants also bear a hydrophobic coating. Useful adjuvants include graphite particles and salts. The median grain size of the crushed glass is below 200 micrometers, preferably below 120 micrometers, for example, in the range of from 25 to 35 micrometers.
