Most all the world uses the propane/butane and not many places in the world use R134a. Did you know R134a caused testicle cancer in laboratory animals? I have never heard of a butane/propane system burning except in tests. However I have saw a number of wrecks on the highway where cars have burned and it was from gas tanks. We are carrying a lot of flammable product in our car, 150lb or more. Butane/propane in the large ac systems is less than 2lb.You have undoubtedly read that propane/butane is flammable, which is true. You have also undoubtedly read that R134 and r12 are not flammable, which it true they way is is in the can or at atmospheric pressure. BUT what they didn't tell you is when mixed with oil and under pressure and sprayed out in a mist as it would be from a ruptured ac line, it is very flammable. So, if I use r134 or r12 I do have flammable product in my system. If I use butane/propane at least I don't have to worry about testicle cancer.
