Which international treaty agreement was the basis for Section 608? | The Montreal Protocol. |
Depletion of the ozone in the stratosphere is known to cause what 6 things? | 1.Crop losses
2.Increases in eye diseases
3.Skin Cancer
4.Reduced marine life

What happens when CFC or HCFC molecules get in the stratosphere & free atoms of Chlorine are set free? | 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 is EPA 608 Type III certification? | Persons who maintain, service, repair, or dispose of low pressure appliances. |
What is EPA 608 Universal certification? | Persons who maintain, service, repair, or dispose of both low and high pressure equipment, as well as appliances. |
HCFC's | HydroChloroFluoroCarbons |
What are HydroChloroFluoroCarbons? | Commonly known as HCFC's, they are a group of man-made compounds containing hydrogen, chlorine, fluorine, and carbon. |
