When transporting cylinders containing used refrigerant, DOT requires that you:
- CORRECT ANSWER - Attach DOT classification tags
What is one of the most serious results of damage to the stratospheric ozone
layer? - CORRECT ANSWER - increased rates of skin cancer in humans
What evidence demonstrates that chlorine in the stratosphere is primarily from
man-made chemicals rather than from natural sources such as volcanoes? -
CORRECT ANSWER - Samples of air taken from the stratosphere over
erupting volcanoes show that volcanoes contribute a small quantity of chlorine
to the stratosphere compared to CFC's and HCFC's
What is being done in the U.S. to stop damage to the stratospheric ozone layer?
- CORRECT ANSWER - Phasing out the use of chlorofluorocarbons and
hydrochlorofluorocarbons
How should disposable cylinders of CFCs, HCFCs, and HFCs be discarded? -
CORRECT ANSWER - Recover all remaining refrigerant, render the cylinders
useless, and recycle the metal.
In addition to fines and being required to appear in court, what penalty can be
imposed on service technicians who violate Clean Air Act provisions? -
CORRECT ANSWER - They may lose their certification
From which of the following does the ozone layer protect the earth? -
CORRECT ANSWER - ultraviolet radiation from the sun
Which refrigerant(s) must be recovered before opening or disposing of
appliances? - CORRECT ANSWER - All three listed (HFC's, CFC's, HCFC's)
Under EPA's regulations, what standards must reclaimed refrigerant meet before
it can be resold? - CORRECT ANSWER - AHRI 700
