However, I don't think that Mt St Helens caused lab rats to grow
second tails or third ears...

The MSDS doesn't mention anything like this.

"Reproductive data on rats show no change in reproductive performance."

"In animal testing, this material has not caused permanent genetic
damage
in reproductive cells of mammals (has not produced heritable genetic
damage)."

Freon did have it's dark side.

If you compare the MSDS, it is roughly equivalent to alcohol.
Actually, I am at far greater risk from alcohol (or those who
have consumed it) than from Freon.
