Section 608 of the Federal Clean Air Act requires technicians to what?-ANSWER-Recover all refrigerants.

The objective of the Clean Air Act is to protect what? -ANSWER-The earth's stratosphere.

HFC's -ANSWER-HydroFlouroCarbon's

CFC's -ANSWER-ChloroFluoroCarbon's

ODP -ANSWER-Ozone Depletion Potential

Which international treaty agreement was the basis for Section 608? - ANSWER-The Montreal Protocol.

Depletion of the ozone in the stratosphere is known to cause what 6 things? -ANSWER-1.Crop losses 2.Increases in eye diseases 3.Skin Cancer 4.Reduced marine life 5.Deforestation 6.Increased ground level ozone

What happens when CFC or HCFC molecules get in the stratosphere & free atoms of Chlorine are set free? -ANSWER-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.
