  1. Which regulation governs the proper evacuation of refrigerants from appliances before recycling in the US?

    Answer: EPA Section 608 of the Clean Air Act

    EPA Section 608 of the Clean Air Act requires certified technicians to recover refrigerants from appliances before disposal or recycling.

  2. A washing machine being disconnected for recycling is still partially full of water. What is the safest approach?

    Answer: Run a spin cycle to remove remaining water before disconnecting

    Running a spin cycle removes residual water safely before disconnection, preventing spills and reducing the unit's weight for transport.

  3. What is the correct way to cap an exposed gas stub-out after removing a gas range for recycling?

    Answer: Install a listed gas cap or plug with a wrench-tightened threaded fitting

    A listed threaded cap or plug must be wrench-tightened onto the stub-out to safely seal the gas line after the appliance is removed.

  4. When sliding a freestanding refrigerator out from its alcove, which technique protects both the floor and the unit?

    Answer: Place appliance sliders or a protective mat under all four feet before pulling

    Appliance sliders placed under all four feet distribute the load evenly and protect flooring while allowing controlled movement.

  5. Which of the following is a sign that a dryer exhaust duct has a dangerous restriction and must not be reinstalled during a replacement?

    Answer: The duct has visible lint accumulation and the dryer interior is unusually hot

    Visible lint buildup combined with excessive dryer heat indicates a restricted duct that is a fire hazard and must be cleaned or replaced before reinstallation.

  6. A portable air conditioner must be prepared for recycling. What step is legally required BEFORE it can be crushed or shredded?

    Answer: Recover the refrigerant using EPA Section 608-certified equipment

    EPA Section 608 mandates refrigerant recovery by a certified technician before any appliance containing refrigerant is destroyed or processed.

  7. What is the purpose of using thread sealant (pipe dope) or PTFE tape on gas fitting connections?

    Answer: To create a gas-tight seal on threaded connections and prevent leaks

    Thread sealant or PTFE tape fills micro-gaps in threaded gas connections to create an airtight seal that prevents gas leaks.
