Excellent idea!
What are the permissible exposure limits
for asbestos?
Employee exposure to asbestos must not exceed
0.1 fiber per cubic centimeter (f/cc) of air, averaged
over an 8-hour work shift. Short-term exposure must
also be limited to not more than 1 f/cc, averaged over
30 minutes. Rotation of employees to achieve
compliance with either permissible exposure limit
(PEL) is prohibited

Negative. Asbestos fibers are cylindrical, like soda straws, at microscopic levels.
Other minerals break down into round particles that aren't as dangerous.
