Title: Foam composition for treating asbestos-containing materials and method of using same

Abstract

A composition for transforming a chrysotile asbestos-containing material into a non-asbestos material is disclosed. The composition comprises water, at least about 30% by weight of an acid component, at least about 0.1% by weight of a source of fluoride ions, and a stable foam forming amount of a foaming agent system having both cationic and non-ionic functionality. A method of transforming the asbestos-containing material into a non-asbestos material using the present composition in the form of a foam also disclosed.
