Abstract
This invention relates to novel compositions and methods for neutralization and solidification of hazardous alkali spills. A dry particulate composition containing an organic neutralizing acid and, materials having varying adsorption rates may be used to neutralize alkaline spills, and solidify the spills to render them harmless. These compositions may be applied to the spills by fire-extinguisher-like delivery devices which spread the compositions on the spills from a relatively safe distance without splattering the hazardous materials.
