EPA 609 TECHNICIAN CERTIFICATION VERIFIED EXAM QUESTIONS AND
ANSWERS - LATEST VERSION 2026
On what date were CFC and HCFC sales limited to technicians with refrigerant
recovery certifications? November 14, 1994 ANSWER
What are technicians required to do under Section 608 of the Federal Clean Air
Act? ANSWER : Get all of the refrigerants back.
What does the Clean Air Act seek to protect? The stratosphere of the earth.
ANSWER HydroFlouroCarbons (HFCs)
ANSWER : Chlorofluorocarbons (CFCs)
ODP: Ozone Depletion Potential ( ANSWER )
ANSWER The Montreal Protocol, which international treaty instrument
served as the foundation for Section 608?
What are the six known causes of stratospheric ozone depletion? ANSWER 1.
Losses from crops
2. A rise in eye conditions
3. Cancer of the Skin
4. A decline in marine life
5. Reforestation
6. Elevated ozone at ground level
What occurs if molecules of CFC or HCFC enter the stratosphere and release
free chlorine atoms? - REPLY Chlorine monoxide (CLO) is created when these
atoms attack ozone molecules. When they collide with another ozone molecule,
two oxygen (O2) molecules are created, and an atom of chlorine acts as a "Free
Agent," restarting the process until one atom of chloride destroys 100,000 ozone
molecules.
On what date did recovery equipment need to have low loss fittings, increased
evacuation levels, and lab certification? November 15, 1993, ANSWER
, What was the deadline for technician certification? November 14, 1994
ANSWER
When was the manufacture of CFCs phased out? December 31, 1995,
ANSWER
EPA 608 Type I certification: what is it? ANSWER : Individuals who fix,
maintain, service, or discard small equipment that use five pounds or less of
refrigerant.
EPA 608 Type II certification: what is it? - REPLY those involved in the
upkeep, repair, maintenance, and disposal of high and extremely high pressure
appliances. with the exception of automobile air conditioning systems and small
appliances.
ANSWER : Those who maintain, service, repair, or dispose of low pressure
appliances are certified under EPA 608 Type III.
EPA 608 Universal certification: what is it? ANSWER : Individuals who take
care of, fix, or discard appliances and low and high pressure equipment.
ANSWER Hydrochlorofluorocarbons, or HCFCs
HydroChloroFluoroCarbons: What Are They? - REPLY They are a class of
artificial compounds that comprise hydrogen, chlorine, fluorine, and carbon and
are commonly referred to as HCFCs.
It is forbidden to fill a recovery cylinder with more than ___% of its weight
capacity. ANSWER 80%
How should cylinders of refrigerant be shipped? With the appropriate DOT
categorization tags, the ANSWER is up-right.
This oil will work with CFCs and HCFCs, but it MUST be used with ALL
HFCs for HVAC and refrigeration. The Polyolester ANSWER
The air quantities of HCFCs are extremely low, measured in parts per million.
ANSWER Trillion
When the annual leak rate above ___, all cooling systems that contain more than
50 pounds of refrigerant need to be fixed. 15% ANSWER
