  1. What is the EPA de minimis exemption under Section 608 that allows venting during normal service operations?

    Answer: Releases that are not avoidable using reasonable measures during good-faith repair

    The EPA allows releases that are unavoidable during good-faith repair, testing, or servicing operations as a de minimis exemption.

  2. Under ASHRAE 15, Group A1 refrigerants are classified as:

    Answer: Lower toxicity, no flame propagation

    Group A1 refrigerants have lower toxicity and no flame propagation, making them the safest classification under ASHRAE 34/15.

  3. Which ASHRAE standard specifically governs the safety practices for refrigerating systems, including machinery room requirements?

    Answer: ASHRAE 15

    ASHRAE 15 (Safety Standard for Refrigeration Systems) governs machinery room requirements, refrigerant quantities, and safe system design.

  4. Under the EPA's refrigerant management program, what leak rate triggers a required repair for commercial refrigeration equipment with more than 50 lbs of charge?

    Answer: 10% per year

    The EPA requires repair when commercial refrigeration systems with >50 lbs of refrigerant exceed a 10% annual leak rate.

  5. What does a pressure-enthalpy (P-h) diagram compliance check verify in a refrigeration system?

    Answer: That operating pressures and temperatures match design conditions within code limits

    A P-h diagram check confirms that actual operating conditions align with design parameters, indicating correct system performance and safety margin compliance.

  6. Under NFPA 70 (NEC), refrigeration equipment in a Class I hazardous location requires what type of electrical components?

    Answer: Explosion-proof or intrinsically safe rated components

    NEC Class I hazardous locations require explosion-proof or intrinsically safe electrical components to prevent ignition of flammable vapors.

  7. Which document must accompany refrigerant cylinders shipped via DOT regulations?

    Answer: Safety Data Sheet (SDS) and proper DOT shipping labels

    DOT regulations require refrigerant cylinders to be accompanied by an SDS and bear proper hazard communication labels during transport.
