02
Front
How can chlorine-containing refrigerants deplete stratospheric ozone?
Back
Ultraviolet radiation breaks down chlorine-containing chemicals in the stratosphere, releasing reactive chlorine that destroys ozone.
03
Front
Does Section 608 cover some refrigerants that do not deplete ozone?
Back
Section 608 also covers many refrigerant substitutes, including HFCs, even though HFCs do not deplete ozone.
04
Front
What injury can liquid refrigerant cause on contact with skin?
Back
Liquid refrigerant contacting skin or eyes can cause a cold burn.
05
Front
What is the maximum general fill level for a recovery cylinder?
Back
Do not fill a recovery cylinder beyond 80% of its rated capacity by weight; warming refrigerant expands and can raise pressure dangerously.
06
Front
Can disposable refrigerant cylinders be refilled?
Back
Disposable refrigerant cylinders must not be refilled.
07
Front
What gas should be used to pressure-test a refrigeration system?
Back
Use dry nitrogen with a regulator and suitable pressure-relief protection. Never use oxygen or compressed air.
08
Front
What should a technician do before recovering refrigerant?
Back
Identify the refrigerant first, then use recovery equipment and a cylinder suitable for it.
09
Front
What does recovering refrigerant mean?
Back
Recovering means removing refrigerant from an appliance and storing it in an external container; it need not be cleaned or tested.
10
Front
What does recycling refrigerant involve?
Back
Recycling cleans recovered refrigerant for reuse, generally in equipment belonging to the same owner, but does not ensure reclamation purity.
11
Front
What distinguishes refrigerant reclamation?
Back
Reclaiming reprocesses refrigerant to the applicable purity standard and verifies that it meets that standard.
12
Front
What does Section 608 generally prohibit during equipment service?
Back
Section 608 generally prohibits intentionally venting covered refrigerants while maintaining, servicing, repairing, or disposing of equipment.
