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

3.Skin Cancer
4.Reduced marine life
5.Deforestation
6.Increased ground level ozone -CORRECT ANSWER 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. -
