recovery? - ANSNovember 14, 1994
Section 608 of the Federal Clean Air Act requires technicians to what? - ANSRecover all
refrigerants.
The objective of the Clean Air Act is to protect what? - ANSThe earth's stratosphere.
HFC's - ANSHydroFlouroCarbon's
CFC's - ANSChloroFluoroCarbon's
ODP - ANSOzone Depletion Potential

Protocol.
Depletion of the ozone in the stratosphere is know to cause what 6 things? - ANS1.Crop losses
2.Increases in eye diseases
3.Skin Cancer

6.Increased ground level ozone
What happens when CFC or HCFC molecules get in the stratosphere & free atoms of Chlorine
are set free? - ANSThese atoms attack Ozone Molecules causing the formation of Chlorine
