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 .

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 .
A
7. A system is considered dehydrated when A ) the vacuum indicator shows you have reached and held
the required finished vacuum . B ) the vacuum pump has run at least 7 hours . C ) the manifold suction
gauge has held a 30 in . hg./760 mm vacuum for 3 hours . D ) you are ready to leave for the day .
A
