A Chlorofluorocarbon (CFC) refrigerant consists of what elements?
carbon, fluorine, chlorine
What causes a CFC molecule to breakdown when it reaches the atmosphere?
UV Light from sun
Ozone molecules consist of how many oxygen atoms?
it contains 3 oxygens
The venting of which group of refrigerants is a concern because it has GWP but not ODP?
HFC refrigerants don't have ozone depletion potential but have global warming potential and that's why we still should not blast refrigerant off into the atmosphere
Does the ozone layer work to increase or decrease the amount of ultraviolet radiation at the earth's surface?
Works to decrease the ultraviolet rays.
Circle the refrigerant that causes the least damage to the ozone layer: R-12, R-22, R-502, R-134a
134A
Does ozone depletion directly cause an increase in smog?
No
What component in a CFC destroys ozone?
Chlorine atom. It separates the 03 into 02 and 01 then the chlorine goes to the next 03 and does the process to split them up again.
What are the two environmental issues which refrigerants contribute to?
Global warming potential and ozone depletion potential
10.Other than refrigerants, name a class of chemicals which destroy ozone?
Halons and Bromine (Blowing agents, fire suppression chemicals, and different kinds of solvents)

Dec 31 1994
12.Can a motor vehicle ever be refilled with a CFC?

16.After what date is it illegal to produce, import or export virgin HCFC's?
Jan 1 2030 (Jan 1 2020 for all except R-123 for jan 1 2030 that's why so late)
17.Can you refill a mobile AC unit with HCFC's?
No
18.Who is the Federal Code of Practice intended to be used by?
INtsalls, services, leak tests, charges, or any work that may result in the release of a halocarbon
19.Which refrigerants does the Ontario Reg. 463/10 refer to?

21.After liquid refrigerant is removed from a system, what should the technician do with any of the remaining vapour?
Flush out with nitrogen
22.What kind of refrigerant oil is used with HFC refrigerants?
Polyolester
23.What is faster, liquid recovery or vapour recovery?
Liquid
24.What usually accompanies a refrigerant leak in a system?
Staining
25.What should be changed regularly on a vacuum pump?
Its Oil
26.Should more than one refrigerant be stored in the same container?
No
27.What is the best gas to use for leak testing a system?
Nitrogen
28.When is a system allowed to be refilled?
When there is a tag less than 6 months old indicating its not leaking
29.When an ODP card expires, does the technician have to attend a full day training program and be re-examined or, a simple recert. Program will do?
