EPA 609 UPDATED COMPLETE QUESTIONS
AND ANSWERS VERIFIED PREPARATION
RESOURCE
●● Each chlorine atom in the stratosphere can destroy how many ozone
molecules?
Answer: 100,000 ozone molecules
●● Which refrigerant contains a CFC?
R500, R12, R113 or R11?
Answer: Theyre all CFC's
●● HYDROCHLORIC FLORICCARBON (HCFC) refrigerant contain?
Answer: Hydrogen, chlorine, flourine and carbon
●● Which refrigerant is a chlorine free refrigerant?
Answer: HFC R 134A
●● What is the result damage to the ozone layer?
Answer: Increases in human skin cancer
,●● According to the EPA, chlorine in the stratosphere is believed to
come primarily from the CFCs rather than from volcanoes because
Answer: -) The rise in the amount of chlorine measured in the
stratosphere over the past 2 decades matches the rise of chlorine which
has different natural sources of chlorune overthe same period
-) The rise of chlorine in the statosphere matches the rise in CFCs over
the same period
-) samples of air taken over erupting volcanoes shows that volcanoes
contribute a small amount of chlorine in the stratosphere compared to
CFCs
-) ALL OF THE ABOVE
●● Which is a violation of the EPA clean air act?
Answer: -) falsifying or failing to keep required records
-) failing to keep evacuation levels before opening or disposing of
appliances
-) knowingly releasing HFC's, HCFCs or CFC refrigerants
-) ALL OF THE ABOVE
●● Discarding of disposable cylinders is accomplished by
Answer: Assuring that all refrigerant is recovered and that the cylinders
are rendered useless then recycle the metal
,●● How much money can be awarded to a person who supplies
information leading to a conviction against the technician who is
intentionally venting refrigerants or violatingsome other provision of the
EPA CLEAN AIR ACT
Answer: $10,000
●● CFC's will no longer be manufactured or imported into the U.S. after
what year?
Answer: 1995
●● Since July 1, 1992 it has been illegal to:
Answer: Knowingly releasing HCF or HCFC refrigerants in the U.S.
●● Which compounds are controlled by the Montreal protocol?
Answer: -) chloric floric carbons
-) hydro chloric carbons
-) halons
-) all of the above
●● EPA regulations cover all AC and refrigeration equipment when
containing what?
Answer: Any refrigerant or refrigerant substitute
, ●● The syntetic substitute currently usedwith blends containing HCFCs
is:
Answer: Alcobenzine
●● What is the significance of atheotropic mixture:
Answer: The mixture combines to act as a single compound refrigerant
●● Cooling occurs in a vapor compression refrigeration system when:
Answer: Refrigerant liquid boils into a vapor
●● Ozone depletion in the stratosphere is what type of problem:
Answer: Its a GLOBAL problem
●● The definition of recover is:
Answer: To remove refrigerant in any condition from a system and store
it an external container without neccesarily testing it
●● Which of the following leak detection methods is considered by the
EPA to be the effective for locating the general area of small leaks?
Answer: Electronic ultrasonic testers
●● Recovery during low ambient temperatures will:
Answer: Slow the recovery process
