I was awakened from a dead sleep when the refrigeration system on a fish processing boat I was working on developed an ammonia leak. It was the chemical equivalent of a full-on slap in the face--brutal stuff. On 6/20/06, Peter Frederick [EMAIL PROTECTED] wrote: One breath of concentrated

likely to kill you outright. This isn't household ammonia solution, it's anhydrous vapor. Very nasty... My father-in-law has largely monocular vision due to an NH3 incident some years ago. It's corrosive and poisonous, and has no place in a mobile environment. It eats copper, and is used

Sorry guys. I still don't get it. I stand by my statement that the hazards of ammonia are blown out of proportion. Just drop a note to your insurance company that you are using amonia based refrigerant in your car. I doubt that any automobile insurance people would have a clue what that

Besides the slight inconvenience of having to jump out of your car at 100 if you get a leak (remember the ejector seat in 007's DB5), has any one heard of crazies attempting to use ammonia refrigerant in a car? I know the stuff is very efficient however I believe it is extremely corrosive.

I recall Rudolf Diesel wanting to exhibit an ammonia refrigerator at (I forget which) World's Fair but being denied due to safety concerns. The idea for his Rational Heat Engine as he called it and a Diesel engine as everyone else calls it, grew from his experience with compressing

Gee, I remember about 20 years ago being in an evacuation of a good sized chunk of a town in upstate NY when the ammonia cycle system at the cold storage I was delivering to sprung a leak. Couldn't go near the place for a couple of days till it was *safe* ( and we were still choking anywhere

A bit tricky, requires high pressure (1000 psi or so), but will run nicely off the exhaust heat. The main problem is that the ammonia is both highly toxic and flamable (read explosive) when released. Peter

Around three lbs, maybe more for the required capacity. Vented into the cabin, it will promptly kill the people in there. Peter
