EPA 608 Certification Graded A+

EPA 608 Certification Graded A+ 1. On what date did restrictions on the sale of CFCs and HCFCs to certified refrigerant recovery technicians begin? - ️ November 14, 1994 2. What does Section 608 of the Federal Clean Air Act mandate for technicians? - ️ Technicians are required to recover all refrigerants. 3. The primary goal of the Clean Air Act is to safeguard what environmental aspect? - ️ The earth's stratosphere. 4. What does the acronym HFC stand for? - ️ Hydrofluorocarbons. 5. What does CFC stand for? - ️ Chlorofluorocarbons. 6. What is the meaning of ODP? - ️ Ozone Depletion Potential. 7. Which international treaty laid the groundwork for Section 608? - ️ The Montreal Protocol. 8. What are six consequences of ozone depletion in the stratosphere? - ️ 1. Crop losses ️ 2. Increased incidence of eye diseases ️ 3. Skin cancer ️ 4. Declines in marine life ️ 5. Deforestation ️ 6. Elevated ground-level ozone levels. 9. Describe the reaction of CFCs and HCFCs in the stratosphere when chlorine atoms are released? - ️ These chlorine atoms attack ozone molecules, resulting in the formation of chlorine monoxide (ClO). After colliding with another ozone molecule, this reaction produces two oxygen (O2) molecules and leaves a free chlorine atom, which can continue the cycle, destroying up to 100,000 ozone molecules. 10. What was the date when recovery equipment became mandatory to be certified by a lab, specifying higher evacuation levels and low loss fittings? - ️ November 15, 1993. 11. When was certification for technicians required? - ️ November 14, 1994. 12. On what date was the production of CFCs phased out? - ️ December 31, 1995. 13. Define EPA 608 Type I certification. - ️ It is for individuals who maintain, service, repair, or dispose of small appliances containing 5 pounds of refrigerant or less. 14. What does EPA 608 Type II certification cover? - ️ It is aimed at individuals who maintain, service, repair, or dispose of high and very high-pressure appliances, excluding small appliances and vehicle air conditioning systems. 15. What is the focus of EPA 608 Type III certification? - ️ It pertains to those who maintain, service, repair, or dispose of low-pressure appliances. 16. What does EPA 608 Universal certification entail? - ️ This certification is for those who maintain, service, repair, or dispose of both low and high pressure equipment as well as appliances. 17. What are HCFCs, and what does the term refer to? - ️ Hydrochlorofluorocarbons, commonly referred to as HCFCs, are a group of man-made compounds composed of hydrogen, chlorine, fluorine, and carbon. 18. What is the maximum percentage of weight that a recovery cylinder can be filled to? - ️ 80% of its capacity. 19. How should refrigerant cylinders be transported? - ️ They should be shipped upright and labeled with the appropriate DOT classification tags. 20. What type of oil is necessary for all HFC applications in HVAC/refrigeration, and can it also be used with other refrigerants? - ️ Polyolester oil must be used with all HFCs and is also compatible with CFCs and HCFCs. 21.

What is the definition of a Type II Appliance? ️High pressure or very high pressure appliances except for small appliances and motor vehicle air conditioning. Refrigeration systems containing more than 5 Lbs. of high or very high pressure refrigerants. What is the definition of a Type III Appliance? ️Low pressure equipment like low pressure chillers.
