CFC EPA Regulations & Safety Compliance 2 — Questions and Answers
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?
- 60%
- 70%
- 80%
- 90% (Correct answer)
Correct answer: 90%
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?
- EPA Form 6200
- No specific form is required; records must be kept on-site (Correct answer)
- EPA Form 8700-22
- A standard bill of lading suffices
Correct answer: No specific form is required; records must be kept on-site
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?
- Continue recovery but note the pressure in the service record
- Stop recovery immediately and transfer refrigerant to a different cylinder (Correct answer)
- Vent excess refrigerant to relieve pressure
- Add nitrogen to balance the pressure
Correct answer: Stop recovery immediately and transfer refrigerant to a different cylinder
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?
- R-22
- R-12
- R-410A (Correct answer)
- R-11
Correct 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: An EPA-certified technician discovers a leak in a commercial refrigeration system with a full charge of 75 pounds. Under current regulations, within how many days must repairs be completed or a retrofit/retirement decision made?
- 30 days
- 60 days (Correct answer)
- 90 days
- 120 days
Correct answer: 60 days
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.
Question 6: Which entity is responsible for enforcing Section 608 refrigerant regulations at the federal level?
- OSHA
- EPA (Correct answer)
- DOT
- NATE
Correct answer: EPA
The U.S. Environmental Protection Agency (EPA) is the federal agency responsible for administering and enforcing Section 608 regulations under the Clean Air Act.
Question 7: What is the maximum allowable leak rate for industrial process refrigeration equipment under EPA Section 608 before repair action is required?
- 10% of charge per year
- 15% of charge per year
- 20% of charge per year
- 35% of charge per year (Correct answer)
Correct answer: 35% of charge per year
Industrial process refrigeration has the highest allowable leak rate threshold at 35% of the full charge per year before mandatory repair action is triggered under Section 608.
