Recover all refrigerants. - Section 608 of the Federal Clean Air Act requires technicians
to what?
The earth's stratosphere. - The objective of the Clean Air Act is to protect what?
HydroFlouroCarbon's - HFC's

Ozone Depletion Potential - ODP
The Montreal Protocol. - Which international treaty agreement was the basis for Section
608?
1. Crop losses
2. Increases in eye diseases
3. Skin Cancer
4. Reduced marine life
5.Deforestation
6.Increased ground level ozone - Depletion of the ozone in the stratosphere is known to
cause what 6 things?
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. - What
happens when CFC or HCFC molecules get in the stratosphere & free atoms of
Chlorine are set free?
