- What is EPA Section 608 certification?
Show answer
A federal certification required for technicians who handle, recover, or dispose of refrigerants in air conditioning and refrigeration systems.- Name the three certification types under EPA 608.
Show answer
Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems).- What is Type I EPA 608 certification for?
Show answer
Small appliances containing 5 pounds or less of refrigerant, such as window units and mini-splits.- What is Type II EPA 608 certification for?
Show answer
High-pressure appliances over 5 pounds, including most commercial and industrial refrigeration systems.- What is Type III EPA 608 certification for?
Show answer
Low-pressure appliances using medium and low-pressure refrigerants, primarily large centrifugal chillers.- What does CFC stand for?
Show answer
Chlorofluorocarbon, a refrigerant that depletes ozone and is banned for new equipment.- What does HCFC stand for?
Show answer
Hydrochlorofluorocarbon, a transition refrigerant with lower ozone depletion potential than CFCs, being phased out.- What does HFC stand for?
Show answer
Hydrofluorocarbon, a refrigerant with no ozone depletion potential but a high global warming potential.- What is ozone depletion potential (ODP)?
Show answer
A measure of a refrigerant's ability to deplete stratospheric ozone, with CFC-11 defined as 1.0.- What is the Montreal Protocol?
Show answer
An international treaty signed in 1987 to protect the ozone layer by phasing out ozone-depleting substances.- What is the Clean Air Act Title VI?
Show answer
The U.S. federal statute that requires EPA 608 certification and regulates refrigerant recovery and disposal.- What is EPA-approved recovery equipment?
Show answer
Equipment rated to recover refrigerant to the EPA standard of 10 mmHg absolute pressure for high-pressure systems or 4 mmHg for low-pressure systems.- What is the difference between recycling and reclamation of refrigerant?
Show answer
Recycling removes moisture and acid on-site; reclamation restores refrigerant to virgin specifications in a certified facility.- Are technicians allowed to knowingly release refrigerant to the atmosphere?
Show answer
No, it is prohibited by the Clean Air Act Title VI.- What is a de minimis refrigerant release?
Show answer
Small amounts of refrigerant released incidentally during connection/disconnection of fittings, allowed if a good-faith effort is made to minimize release.
