I talked to punisher after he soldered his while it was full of propane(not something you usually want to do) and it just made a fireball....Big deal.
Oh by the way he got banned from here,thats why you havent heard from him 
R290 is a safe refrigerant if you know what your doing.Even if it had a slow leak over night and you turned your light switch on,what do you think would happen?Nothing,thats what would happen.
I have had my room full of propane,smells horrible,but I didnt get some crazy out of control fire.

|Punisher| was banned for promoting the use of propane as a refrigerant, while clearly not taking the time to discuss the dangers, nor the safety measures required to handle/use it safely. He was wreckless, period.
If you have HVAC training, then I would encourage you to share the RELEVANT information, instead of blindly promoting R290 (propane). Otherwise, you will get banned too.
And no, testing a theory by pressing a torch against a system loaded with propane DOES NOT constitute relevant experience/knowledge. It was, and still is foolish to try it.
This "little fireball" may not seem to be a big deal to you, but for everyone else out there, it could become one, as it ignites something else, starting a REAL fire.
As for your room being full of propane, you certainly did get lucky. Had a fire started, you would not be around to tell us about it, now would you?
