Type II — High-PressureQuestion 151 of 240
Virgin (newly produced) HCFC-22 was subject to a production and import phaseout. As of January 1, 2020, what happened to the supply of virgin R-22?
a.Production and import of virgin R-22 was banned, leaving only recovered, recycled, and reclaimed R-22 for servicing
b.R-22 became unregulated and freely available
c.R-22 could be vented if recovery was inconvenient
d.All R-22 equipment had to be destroyed immediately
Explanation
As of January 1, 2020, the production and import of virgin HCFC-22 was banned in the United States, so only recovered, recycled, or reclaimed R-22 is available to service existing equipment. This makes careful recovery and reclamation more important than ever. Venting R-22 remains illegal, and existing equipment may keep operating.
