system less than 1 year old .. D ) is recovered from a system still under
warrantee . - correct answer B
5. 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 : A ) revocation of the
technician's certification . B ) seizure of the technician's recovery or
recycling equipment . C ) seizure of any refrigerant purchased by the
technician which is still in his / her possession . D ) mandatory
attendance at a refrigerant training camp . - correct answer A
6. What characteristic ( s ) of CFCs make them more likely to reach the
stratosphere than most other compounds containing chlorine ? A )
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 ozone , causing it to change back to
oxygen , thus destroying the ozone layer . B ) CFCs are lighter than other
damaging compounds , making it easier for them to float upward when
released . C ) CFCs are attracted to the static in the atmosphere . D )
CFCs are attracted to dust in the atmosphere . - correct answer A
