Read the first 7 Regulations, Codes, and Safety Standards flashcards as text

  1. Under EPA Section 608 regulations, which type of refrigerant release is considered a violation?

    Answer: Knowingly venting HFC refrigerants during servicing

    EPA Section 608 explicitly prohibits the knowing venting of HFCs (and CFCs, HCFCs) during maintenance, service, repair, or disposal of refrigeration equipment.

  2. Which organization issues the ENERGY STAR certification for residential central air conditioners, and what minimum SEER2 is typically required?

    Answer: EPA; 15.2 SEER2

    The EPA administers the ENERGY STAR program, and as of 2023 the minimum threshold for central AC certification is generally 15.2 SEER2 in northern regions and higher in the South.

  3. Under current DOE regulations effective January 1, 2023, what is the minimum SEER2 requirement for split-system central air conditioners in the Southwest and Southeast U.S.?

    Answer: 14.3 SEER2

    DOE's regional standards effective January 2023 require a minimum of 14.3 SEER2 for split-system central ACs sold in the Southeast and Southwest climate regions.

  4. What action must a technician take under EPA Section 608 if a system with more than 50 pounds of refrigerant is found to be leaking above the applicable threshold rate?

    Answer: Repair the leak within 30 days or develop a retrofit or retirement plan

    EPA Section 608 requires that leaks exceeding the threshold be repaired within 30 days of discovery; if repair is not feasible, a retrofit or retirement plan must be developed within 30 days.

  5. Which NFPA standard governs the use of refrigerants and refrigerating systems in buildings, complementing ASHRAE 15?

    Answer: NFPA 55

    NFPA 55 (Compressed Gases and Cryogenic Fluids Code) addresses storage and use of compressed gases including refrigerants in buildings, working alongside ASHRAE 15.

  6. What is the maximum amount of R-410A that can be stored in a single control area of a building under IFC (International Fire Code) limits before additional safeguards are required?

    Answer: 220 pounds

    The IFC limits the storage of R-410A (a nonflammable liquefied gas) to 220 pounds per control area without additional hazardous materials controls.

  7. Under ASHRAE Standard 34, what does a refrigerant safety group designation of 'A2L' indicate?

    Answer: Low toxicity and mildly flammable with low burning velocity

    ASHRAE 34 classifies A2L refrigerants as lower toxicity (A) with mildly flammable characteristics and a maximum burning velocity of ≤10 cm/s (2L), such as R-32 and R-454B.
