Question 1

Under Section 608 of the Clean Air Act, what is the minimum recovery efficiency required when servicing appliances containing less than 200 pounds of refrigerant using a system-dependent (passive) recovery device?

Accepted Answer

90%

Answer

System-dependent (passive) recovery devices must achieve 90% recovery efficiency for appliances with less than 200 pounds of refrigerant under EPA Section 608 rules.

Question 2

Which EPA form must technicians use to document refrigerant recovered from appliances with a charge of 5 to 50 pounds before disposal?

Accepted Answer

No specific form is required; records must be kept on-site

Answer

EPA Section 608 does not mandate a specific federal form; instead, technicians must maintain on-site records of refrigerant recovery for appliances in that charge range.

Question 3

What action must a technician take if a recovery cylinder's pressure exceeds the Department of Transportation (DOT) rated pressure during recovery?

Accepted Answer

Stop recovery immediately and transfer refrigerant to a different cylinder

Answer

If cylinder pressure exceeds the DOT-rated working pressure, recovery must stop and refrigerant must be transferred to an approved cylinder to prevent rupture.

Question 4

Under EPA Section 608, which of the following refrigerants is classified as a substitute refrigerant and subject to SNAP program review?

Accepted Answer

R-410A

R-410A is a hydrofluorocarbon (HFC) blend reviewed under the EPA's Significant New Alternatives Policy (SNAP) program as a substitute for ozone-depleting substances.

Question 5

Accepted Answer

60 days

Answer

For commercial refrigeration systems, the EPA requires that leak repairs be completed or a decision to retrofit or retire the equipment be made within 30 days, but an extension to 60 days may apply with documentation.
