2 If it is, in fact, airborne asbestos, the
3 potential hazard for asbestosis is wherever it is.

5 Q Could you describe briefly bearing in mind
6 the hour of the day the reason why one used asbestos
7 fibers in hydrous calcium silicates?
8 A The insulation products were subject to
9 physical damage breaking, cracking.
10 Asbestos was used as a reinforcing medium in
11 the formulation of calcium silicate, and 85 percent
12 magnesium.
13 And it had superior properties in that

18 was an absence of a satisfactorily commercially
19 feasible alternative to asbestos fibers at least to
20 the high temperature insulation?
21 A That is correct, to the best of my
