I work with hydrocarbon refrigerants - basically highly refined propane and isobutane (No its not BBQ gas) 
 
Typically with HC as a refrigerant approximately 200 - 300 grams is used, and during this training class I have one protagonist who was stiring up the class - saying it was dangerous, he was a real pain....
...Yep he was running his car on LPG from this BBQ cylinder (maybe 9 - 10 kgs) sat inside the car.............
 
.....................and he was having a pop at HC refrigerants  @ 200 grams.
 
I had to laugh .............
