  1. Which OSHA standard applies to the safe handling and storage of compressed gas cylinders, including refrigerant cylinders, in the workplace?

    Answer: 29 CFR 1910.101

    OSHA 29 CFR 1910.101 covers compressed gases in general industry, including requirements for cylinder storage, handling, and use.

  2. A cylinder labeled 'ODP' refrigerant is found in a service shop. What does this designation signify for storage purposes?

    Answer: The cylinder contains a refrigerant with Ozone Depletion Potential and may require additional regulatory compliance

    ODP (Ozone Depletion Potential) refrigerants are subject to EPA Section 608 venting prohibitions and additional handling/disposal requirements under Clean Air Act regulations.

  3. What is the correct orientation for storing most liquid refrigerant cylinders (such as 30 lb cylinders) during long-term storage?

    Answer: Vertical, valve end up

    Refrigerant cylinders should be stored valve-end up so that only vapor (not liquid) contacts the valve, reducing the risk of liquid slugging or uncontrolled liquid release.

  4. A technician is disposing of an empty non-refillable refrigerant cylinder. Which step is required before disposal in most jurisdictions?

    Answer: The cylinder valve must be removed or the cylinder rendered unusable to prevent illegal refilling

    To prevent illegal refilling, empty non-refillable cylinders must typically be rendered unusable (e.g., valve removed, cylinder punctured) before disposal.

  5. Which gas is strictly prohibited from being stored in the same area as refrigerant cylinders due to risk of catastrophic reaction?

    Answer: Acetylene and other flammable/oxidizing gases (where separation rules apply)

    Flammable gases like acetylene and oxidizers must be segregated from refrigerant cylinders per OSHA and NFPA rules to prevent fire and explosion hazards.

  6. What information is a technician required to record when transferring recovered refrigerant into a recovery cylinder?

    Answer: The type of refrigerant, quantity recovered, date, and technician certification number

    EPA Section 608 regulations require technicians to keep records of recovery operations, including refrigerant type, amount, date, and the technician's certification number.

  7. During a recovery operation, the recovery cylinder becomes warm to the touch. The BEST action is to:

    Answer: Stop recovery and allow the cylinder to cool, or switch to a second cylinder to prevent overfilling

    Warming indicates increasing pressure as the cylinder fills; pausing recovery or switching cylinders prevents overpressure and ensures safe operation.
