Tak calkiem nieszkodliwy nie jest

Recently, 1,1,1,2-tetrafluoroethane has been subject to use
restrictions due to its contribution to climate change.[12] It has a
global warming potential of 1300.[13]

The Society of Automotive Engineers (SAE) has proposed
1,1,1,2-tetrafluoroethane to be best replaced by a new fluorochemical
refrigerant HFO-1234yf (CF3CF=CH2) in automobile air-conditioning
systems.[14] California may also prohibit the sale of canned
1,1,1,2-tetrafluoroethane to individuals to avoid non-professional
recharge of air conditioners.[15] A ban had been in place in Wisconsin
since October 1994 under ATCP 136 prohibiting sales of container sizes
holding less than 15 lbs of 1,1,1,2-tetrafluoroethane, but this
restriction applied only when the chemical was intended to be a
refrigerant. However, the ban was lifted in Wisconsin in 2012.[16]


Research suggests that over the past 10 years the concentration of
1,1,1,2-tetrafluoroethane has increased significantly in the Earth's
atmosphere, with a recent study revealing a doubling in atmospheric
concentration between 2001 and 2004.

Ciekna te samochody. A moze nie tylko, bo ponoc to bylo w
"sprezonym powietrzu w puszkach".
