The same system or other systems owned by the same person without restriction
Used in any system serviced that day
Sold as used refrigerant to other customers
Called reclaimed if a filter-drier was used during recovery
Was processed in a reclaiming machine
Has been chemically analyzed and the refrigerant meets the ARI 700 purity standard.
Is recovered from a system less than 1 year old
Is recovered from a system still under warranty.
Revocation of the technician's certification
Seizure of the technician's recovery or recycling equipment.
Seizure of any refrigerant purchased by the technician which is still in his/her position.
Mandatory attendance at a refrigerant training camp
Refrigerants that contain chlorine but not hydrogen are so stable that they do not break down in the lower atmosphere after being released. The chlorine or bromine reacts with ozone causing it to change back to oxygen, thus destroying the ozone layer.
CFCs are lighter than other damaging compounds, making it easier for them to float upward when released.
CFCs are attracted to the static in the atmosphere
CFCs are attracted to dust in the atmosphere.
The vacuum indicator shows you have reached and held the required finished vacuum.
The vacuum pump has run at least 7 hours.
The manifold suction gauge has held a 30in hg./760 mm vacuum for 3 hours
You are ready to leave for the day
Both a and b
It is always made from just two components
It has a pressure-temperature curve identical to one of its components.
It is a mixture that is always made from at least three component refrigerants
It is a mixture that acts like a single-component refrigerant over its entire range.
They have identical ODP's.
They both contain hydrogen.
They have the same normal boiling points.
They must be recovered before opening or disposing of applicances.
As a vapor
At very high temperatures
As a liquid.
The same as any other refrigerant
Faster than other refrigerants
In uneven amounts due to different vapor pressures.
Slower than other refrigerants
Only if the joint falls completely
The rise in the amount of chlorine in the stratosphere matches the rise in the amount of fluorine, which has different natural sources than chlorine
The rise in the amount of chlorine in the stratosphere matches the rise in CFC emissions
Air samples taken from the stratosphere over erupting volcanoes show that volcanoes contribute a small quantitiy of chlorine to the stratosphere when compared to CFCs
