Propane is toxic? AFAICT it's no more toxic than good ol' Nitrogen. I'm
having trouble finding an MSDS whose toxicology section says it is more
than an asphyxiant, or that the liquid can boil on your skin and cause
frostbite.
I'd still be wary of using it in an A/C because of the flamability and
possibly increased pressures.

What sort of pressures do normal freon based A/Cs use? LPG tanks are
usually rated for 300 psi, so I suspect that would be the worst that
the A/C would need to handle...

Apparently you aren't man enough to apologize for a mis-statement, when the
real problem was you don't comprehend what you read.

Re: I need R-12
Propane's toxicity probably is more relevant to its behavior in the presence
of oxygen & flame.
