True, much ranting mostly from people who never tried it, and from AC shops. They even got some states to outlaw HC's. The EPA hasn't helped at all, even though HC seems the best future option. Read up on the new HO1234yc and the HF gas it produces in a fire. M-B refused to use it in cars shipped to France, lawsuits, ... 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. Fear carrying a newspaper in the car more.
