AND
Required level of evacuation for Low Pressure appliances before
this date was 25 inches Hg, after this date 25 mm Hg
,Nov 14 1994-

Nov 15 1995-
Violation to vent HFCs
Dec 31 1995-

ANS Memorize it, ya'll.
3.Comfort cooling appliances containing more than 50 lbs of
refrigerant must be repaired when the annual leak rate exceeds
%
ANS 15%
4.Commercial and Industrial process refrigeration containing
ore than 50 lbs of refrigerant must be repaired when the annual
leak rate exceeds %
ANS - 35%
5.Required Recovery Levels for Type II appliances, before and
after 11/15/93
,HCFC22 less than 200 lbs = B4-0 After-0
HCFC22 more than 200 lbs= B4-4 After-
10 NonHCFC22 less than 200 lbs= B4-4
After 10 NonHCFC22 more than 200 lbs=
B4 4 After 15 Very high pressure
appliances= B4-0 After-0

6.Section 608 of the Federal Clean Air Act requires technicians
to what?
ANS Re- cover all refrigerants.
7.The objective of the Clean Air Act is to protect what?
ANS The earth's stratos- phere.
8.HFC's
ANS HydroFlouroCarbon's
9.CFC's
ANS ChloroFluoroCarbon's
, 10.ODP
ANS Ozone Depletion Potential
11.Which international treaty agreement was the basis for
Section 608?
ANS The Montreal Protocol.
12.Depletion of the ozone in the stratosphere is known to
cause what 6 things?
ANS 1.Crop losses
2. Increases in eye diseases
3. Skin Cancer
4. Reduced marine life
5. Deforestation
6. Increased ground level ozone
13.What happens when CFC or HCFC molecules get in the
stratosphere & free atoms of Chlorine are set free?
ANS These atoms attack Ozone Molecules causing the formation of
Chlorine Monoxide (CLO), after colliding with another Ozone Molecule,
causes 2 Oxygen (O2) molecules to be made & leaving an atom of
chlorine to act as "Free Agent" starting the process over until 100,000
molecules of Ozone are destroyed by just one atom of chloride.
