EPA SECTION 608 PREPARATORY MANUAL: CORE AND
TYPE 1 TECHNICIAN EXAM QUESTIONS AND ANSWERS
What ozone layer is earth's protective shield? - correct answer
Stratospheric ozone
What is ODP? - correct answer Ozone Depletion Potential.
Measures the ability of a substance to destroy ozone in
the stratosphere.
How does depleting stratospheric layer affect humans
and environment - correct answer Global Warming. Skin cancer.
Cataracts.
Decreased Crop yield
,EPA SECTION 608
Damage to Marine organisms
Which chemical containing refrigerants affect the
depletion of the stratospheric layer? - correct answer Chlorine
containing refrigerants.
Ozone in the stratosphere consists of molecules
containing __ oxygen atoms - correct answer 3
____ is the element of a CFC and HCFC molecules that
causes ozone depletion - correct answer Chlorine
What happens when a chlorine atom encounters an
ozone molecule? - correct answer It takes one of the ozone 3
oxygen atoms forming a compound called chlorine
monoxide (CIO) leaving an oxygen 02 molecule behind.
How long does a single chlorine atom last in the
Stratosphere and how many molecules does it destroy? -
correct answer It can last in the stratosphere for 120 years and
destroy up to 100,000 ozone molecules
, EPA SECTION 608
The chlorine in CFCs and HCFCs will neither dissolve in
water nor break down into compounds that dissolve in
water. (so they do not rain out of the atmosphere) T/F -
correct answer True
What are HFCs? Do they contain Chlorine? High or Low
GWP? - correct answer Hydrofluorocarbons. They do not
contain Chlorine. High GWP.
What is GWP? - correct answer Global Warming Potential. Was
established to provide comparisons of the global
warming impacts of different gases over a span of time.
Which molecule is used as the baseline measurement for
GWP and has a value of 1 - correct answer Carbon Dioxide
(CO2)
R-410A is not a HFC. T/F - correct answer False
