100
R-134a is an example of what type of Gas and contains what elements
What is a HFC and contains Hydrogen, Fluorine and Carbon
100
These are the two basic types of recovery devices
What are System dependent & Self-contained devices
100
This is to remove refrigerant in any condition from a system and store it in an external container without necessarily testing or processing it in any way
What is Recover
100
Portable refillable tanks or containers used to ship recovered refrigerants must meet what standards of what government agency
What is DOT (department of transportation)
100
The EPA section 608 certification must be renewed how often
What is NEVER
200
It is estimated that a single chlorine atom can destroy how many ozone molecules
What is 100,000
200
There are three reason why recover is important
What is - adequate supplies of refrigerant after production bans - prevents venting to the atmosphere - prevents Ozone depletion
200
Recovery equipment used for the service or repair of small appliances must be certified by an EPA approved lab if the recovery equipment was made after
What is November 15, 1993
200
Large spills of refrigerant can cause suffocation because:
What is they are heavier than air & displace oxygen
200
After 1995, any supplies of CFC refrigerant to service existing units in the USA must come from
What is recovery and recycling
300
If Ozone is depleted, the harmful Ultra Violet rays from the Sun reach the earth resulting in what problems (name three)
What is -Increased temperature on the earth - Increased cases of skin cancer - Increased numbers of cataracts - Crop & vegetation loss - Reduced marine life loss
300
If you smell a strong odor during the recovery process it is likely this has happened
What is the compressor has burned out
300
Before beginning a refrigerant recovery procedure it is always necessary to:
What is determine the type of refrigerant in the system
300
In the event of a large release of R-12 or R-22 in a contained area
What is you should wear a "SCBA" or leave the area is required
300
Recovery or recycling equipment which was manufactured after 11-15-93 and is used to recover refrigerant from small appliances prior to the disposal of the small appliance must be used to
What is recover 80% of the refrigerant if the compressor isn't working and 90% on one with a working compressor
400
R-11, R-12 and R-500 have these things in common and are what type of Gas
What is Chlorine, Flourine and Carbon and are CFC's
400
EPA's definition of a small appliance includes:
What is a device manufactured, charges & hermetically sealed in factory with a charge of 5lbs or less
400
When recovering refrigerant into a non-pressurized container from a refrigerator with an improper compressor:
What is it is necessary to heat & strike the compressor with a rubber mallet
400
MSDS is defined as and contains this
What is Material Safety Data Sheet and contains the chemical and solvents that are being handled.
400
As of this date, CFC's can no longer be legally manufactured or imported into the US
What is December 31,1995
500
This, has the highest ODP
What are CFC's
500
These affect the speed of the recovery process
What is - hose diameter -ambient temperature - hose length - size of the refrigerant system
500
This is to process refrigerant for immediate reuse by separating the oil from the refrigerant and removing moisture and acidity from the refrigerant by use of products like filter driers.
What is Recycle
500
This is used for visual inspection of refrigerant and if icing occurs you should always use this
What is Sight glasses and alcohol spray
500
As of this date, technicians servicing small appliances must be EPA certified.
What is November 14, 1994
