Freon/oil/concerns?

Do not! Under any circumstances flush/purge any refrigeration system with air. This will cause a chemical reaction and produce large amounts of phosgene gas which could explode when heated. I am by Trade a HVAC Technician.
USE NITROGEN.

If you feel a light burn in your lungs you are breathing in phosgene. I've had 15 ft flames shoot out of condensing units with accumulators that had not released all their refrigerant prior to trying to braze in a new compressor.

Do you have any info on plasma , O/A or saw cutting on empty freon containers? Weird question, but for yard art.

A lot of those containers at one time were used as portable air tanks when empty. As far as cutting any of them with something that generates heat. I wouldn't advise it. Stay a away from the old R-12 or R-22 containers with heat. There is not a good way to purge those small tanks. Just best to throw them in the scrap pile when empty.
