The EPA can require a technician to demonstrate their ability to perform proper procedures for
recovering and/or recycling refrigerant. Failure to demonstrate competency can result in: - -
(Correct Answer)revocation of the technicians certification.
What characteristic(s) of CFCs make them more likely to reach the stratosphere than most other
compounds containing chlorine? - - (Correct Answer)Refrigerants that contain chlorine but not
hydrogen are so stable that they do not break down in the lower atmosphere after being released.
The chlorine or bromine reacts with the ozone, causing it to change back to oxygen, thus
destroying the ozone layer.

in common? - - (Correct Answer)It is a mixture that acts like a single-component refrigerant over
its entire range.

Data shows that chlorine in the stratosphere comes mainly from CFCs rather than from natural
sources such as volcanoes because: - The rise in the amount of chlorine in the stratosphere
matches the rise in the amount of fluorine, which has different natural sources than chlorine; The
rise in the amount of chlorine in the stratosphere matches the rise in CFC emissions; Air samples
