Individuals residing or working in buildings with insulation or other building materials that may potentially contain asbestiform minerals (for example, vermiculite from the Libby, Montana, mine) are encouraged to ensure that the insulation material is solidly contained and not able to be disturbed and become airborne. If the material is to be removed, special procedures must be followed that minimize the generation of dust and specify appropriate locations for disposal. Individuals can obtain information about asbestos removal and disposal procedures from the 10 regional offices of the EPA. 

Definitions of Terms Used To Discuss Health Effects from Asbestiform Minerals... 

Amphibole A large group of silicate minerals with more than 40-50 members (Leake 1978 Leake et al. 1997). The molecular stmcture of all amphiboles consists of two chains of Si04 molecules that are linked together at the oxygen atoms. In the earth s cmst, amphibole minerals are mostly nonasbestiform asbestiform amphiboles are relatively rare (Veblen and Wylie 1993 Zoltai 1979, 1981). See definitions of asbestiform, mineral, and mineral habit. Also see the Chemistry of Amphibole Minerals section.
