When shipping refrigerant that has been used, which of the following must we do?

• A. Attaching DOT classification tags
• B. All of the above
• C. Use recovery cylinder
• D. Properly label contents

Answer: (B)

Shipping used refrigerant requires following hazmat rules that cover tagging, labeling, and the container used. Attaching DOT classification tags is required because it communicates the hazard class and UN number to carriers, guiding safe handling and routing. Properly labeling contents is essential so anyone handling the package can quickly identify what’s inside and the associated hazards, enabling proper emergency response. Using a recovery cylinder is also necessary because used refrigerants must be recovered and not vented to the atmosphere; the recovery cylinder is designed to safely store and transport recovered refrigerant and meets required standards. Since each of these steps serves a different regulatory and safety purpose, all of the above must be done.
