Under EPA 608, what is the maximum allowable annual leak rate for a commercial refrigeration system containing more than 50 pounds of refrigerant?
Answer: 35%
EPA 608 sets a 35% annual leak rate threshold for commercial refrigeration systems holding more than 50 pounds of refrigerant before mandatory repair is required.
Which refrigerant is classified as an A2L (mildly flammable) by ASHRAE Standard 34?
Answer: R-32
R-32 is classified as A2L because it has low toxicity (A) and mild flammability (2L) per ASHRAE 34 safety classifications.
What does the term 'de minimis' refer to in the context of EPA 608 refrigerant regulations?
Answer: A small release allowable during normal servicing
De minimis releases are small, unavoidable refrigerant releases that occur during normal servicing and are not prohibited under EPA 608.
A technician must repair a leak in a comfort cooling system with more than 50 lbs of refrigerant within how many days of discovery?
Answer: 30 days
EPA 608 requires repairs to comfort cooling systems exceeding 50 lbs of refrigerant to be completed within 30 days of discovering the leak.
Which type of recovery equipment must be used when the refrigerant system's compressor is operational?
Answer: System-dependent (passive) recovery equipment
System-dependent recovery equipment relies on the system's own compressor to push refrigerant into the recovery cylinder and requires the system compressor to be working.
What is the primary environmental concern with high-GWP refrigerants like R-404A?
Answer: Contribution to climate change
R-404A has a GWP of approximately 3,922, meaning it contributes significantly to climate change when released, though it has zero ozone depletion potential.
Under EPA 608, technicians who purchase refrigerant in containers larger than 2 pounds must have which of the following?
Answer: EPA 608 certification
