Enviro-safe is selling R600a. More commonly known as iso-butane. Butane, you know, the stuff they put in cigar lighters. Its a hydrocarbon, a fuel, its flammable.
True, it makes a great refrigerant, but the SAE thought it best to avoid using flammable refrigerants, because the refrigeration system cycles through the engine compartment AND the passenger compartment. A leak in either area could be disastrous.

Not to mention, in a front end, or in the case of the Pantera a rear end collsion, the first thing to get hit and start leaking is the a/c cond. Butane is not something you want leaking out especially during a accident. Unfortantly I'm seeing more and more a/c systems charged with it. In fact my recycler machine has a warning sensor to protect against contamination of butane. I'd pass on it.
