In the wisdom of our govt thinking we are to blame for the "hole contained by the ozone" over Antarctica, which BTW comes and goes, You enjoy to "recover" the refrigerant. A recovery device is the only approved channel (unless it contains I believe 5 Oz's refrigerant then you can or could buy a refrigerant "bag" and appropriation the refrigerant in it. Ive never worked next to this small amount nor a bag but hold read about them). Anyone that have an EPA license should know where you can return with borrow or rent one or hire someone especially in the HVAC business to hold it out. In the old days we broke lines and consent to it out slowly so has not to consent to the oil out too and get a mess. Be advised that here is not a health instructive other than suffocation on the subject of refrigerant as it displaces oxygen. Its not advisable to smoke around it cause the warmness or any open flame or electrical arcing cause the refrigerant to break down to phosgene gas and hydrocloric acid. but the refrigerant surrounded by stable state is has not be proven to be toxic.
But Alas the penguins in Antarctic are immediately disappearing but its not from refrigerant being contained by the atmosphere. And if the earth is warm up we may not be the cause. A long road to answer a simple question I know but we permit doo gooders run way too much of our go and govt.
