  1. Under the Uniform Fire Code, what minimum ventilation requirement applies to rooms where refrigerant recovery cylinders are stored?

    Answer: Mechanical ventilation providing at least 1 air change per hour at floor level for heavier-than-air refrigerants

    Fire codes require mechanical ventilation at floor level for rooms storing heavier-than-air refrigerants to prevent dangerous accumulation in low areas.

  2. Which EPA requirement governs the certification of reclaimers who accept recovered refrigerant from appliance recyclers?

    Answer: Section 608(c)(2) requiring EPA certification for refrigerant reclaimers

    EPA Section 608(c)(2) requires that reclaimers restore used refrigerant to ARI 700 purity standards and register with the EPA.

  3. What does the GWP value on a refrigerant's safety data sheet indicate, and why is it relevant to appliance recycling compliance?

    Answer: Global Warming Potential — relevant for HFC phase-down tracking and reporting under the AIM Act

    GWP (Global Warming Potential) measures a refrigerant's climate impact relative to CO2, which is critical for compliance with the AIM Act's HFC allocation and phase-down rules.

  4. The AIM Act (American Innovation and Manufacturing Act of 2020) authorizes EPA to phase down HFCs by what percentage compared to baseline by 2036?

    Answer: 85%

    The AIM Act sets an 85% HFC phase-down from the US baseline by 2036, following a step-down schedule starting in 2022.

  5. A recycling technician discovers foam insulation in an appliance contains HCFC-141b as a blowing agent. How should this material be handled under EPA rules?

    Answer: Foam must be processed using equipment that captures the blowing agent to prevent venting

    EPA requires that foam blowing agents (including HCFC-141b) be captured during shredding or demanufacturing to prevent ozone-depleting substance emissions.

  6. Under OSHA's Lockout/Tagout standard (29 CFR 1910.147), which step must occur FIRST before a technician begins recovering refrigerant from an appliance compressor?

    Answer: Isolate and de-energize the appliance and verify zero energy state

    LOTO requires that all energy sources (electrical) be isolated, locked out, and verified at zero energy state before beginning any service work on the compressor.

  7. Which federal standard requires that appliance recyclers receiving appliances through a utility rebate program maintain records of refrigerant recovery for a minimum period?

    Answer: Three years

    EPA Section 608 requires that records related to refrigerant recovery, including amounts and disposal methods, be retained for a minimum of three years.
