Abstract
A fire control composition which is in particulate form, which is anhydrous, and which is particularly effective for fighting Class D fires, such as metal fires. The composition includes 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 may additionally contain at least one additional material, such as salts, spherulized vitreous beads, or graphite which at least one additional material also bears a hydrophobic coating. The median grain size of the crushed glass is preferably below 200 micrometers, most preferably below 120 micrometers, for example, in the range of from 25 to 35 micrometers.
