Read and decide for yourself. HC refrigerant is now widely used in Canada and in home refrigerators in Europe. Your EPA quotes support my statement that they are "not helpful". Venting HC to the atmosphere is as bad for the environment as a cow fart (actually a valid concern for global warming). If concerned of the danger, try pouring some liquid from the can on the ground and light it like I did. Not even as scary as a wax candle.

The OP did NOT mention it.... you brought it up in the third post of the thread.
How fast do those REFRIGERATORS travel ? How often do the CRASH into something ?
"Some claim HC can "explode", but impossible unless pre-mixed with air. All refrigerants (and their oils) can burn if a hose is punctured and blows on a hot turbo or exhaust, and some produce poisonous gases. 12 oz of HC is minimal mass to burn. I lit some I collected and it burned very slowly, similar to a wax candle. It can only burn as fast as the cold liquid gets vaporized."--BillGrissom
More misdirection... it is under pressure.... already combined with oil ....
and we do not need to confine this to a situation where it is blown onto a hot exhaust...
The danger is in the fact that it is up at the front of the car with basically no protection. Not even the radiator is in from of the Condenser... and in a collision where we have an HC spraying out under pressure the flash point for a fire is way lower than what you poured out and ignited.
The question is not about ' minimal mass to burn' it is about FIRE or NO FIRE... if we used the term ' Propane' and the fact that SPARKS in a normal accident can ignite that gas.... that is the situation we are preaching against... since it is an UNNECESSARY DANGER.....
One more thing ... if a person needs to get their system serviced on a trip.. try finding a shop which will touch it with a Hydrocarbon in it...
And another thing which is seldom mentioned in the refrigerant discussions... particularly important for R4 compressors.... which have NO oil reservoir ... is that of the system oil being ' mixable' in the refrigerant so it can take it around the system and keep the compressor lubed.... We know R12 has an oil which will work...and R134 does....
