John,
    I would think that the AC is by design a high
pressure system that can handle much higher pressures
than the propane tank.   I am sure somone out there
could tell us what the high pressure side of the ac is
in comparison to the proximal pressure of the propane
tank.   To me the real danger is the 16 gallons of gas
we all carry around.   May are injection system all
stay tight.     many flame free miles to us  all,
       gary                    From:    Vidovich John

<I use r-134 which cools marginally and if I thought
es-12 would cool better and I was switching from r-12
I would not worry about the burning issue. >
 It's not the burning per se, it's the explosion that
is of concern.

< First of all the amount of gas in comparison to the
propane you
are already carrying is small.   It is in a sealed
system without oxygen.   If a leak develops the gas
will dissipate quicky.>
The propane tank is in a specially designed and tested
vessel that
should
withstand severe impact and pressure rise. The AC
system in not
designed to
the same DOT/ASME standards - actually not even close.
Your right,
since
there is no O2 in the system, it won't cause a problem
until it leaks
out and
mixes with air. For the same reason you wouldn't check
your propane
tank for
leaks with match.
Small amount is also a relative term How long will 3
lbs of propane
last in
your BBQ. What if all of that energy was realsed at
once (ie.
explosion)?

<If you are going to worry about es-12 you should not
use the propane and for that matter the gas in your
tank which represent a much greater hazard.>

Not so.... see above

These are two totally different types of systems - one
designed with
all the
appropriate safety measures and one not. Just think
about it before
betting
yours and some one elses life. Believe me, I wish this
stuff were safe,
I'd
use it in a heartbeat. Think   "works great, blows
up".
