Which action is required when disposing of equipment that contains refrigerants, including substitutes?

• A. Vent the refrigerant to the atmosphere
• B. Drain all liquids but not gases
• C. Store the equipment indefinitely without action
• D. Recover the refrigerant before disposal

Answer: (D)

Recovering the refrigerant before disposal is required because you must remove all refrigerant from equipment so it won’t be released into the atmosphere. This protects the environment by preventing ozone depletion and greenhouse gas emissions, and it’s a legal obligation under EPA rules. Substitutes count too—whether it’s a traditional refrigerant or a modern replacement, the gas must be recovered rather than vented or left in the unit.

Venting refrigerants to the air is prohibited and harmful, and simply draining liquids ignores the gaseous refrigerant still inside the system. Storing the equipment without taking action avoids disposal responsibilities and risks leakage over time. The correct approach is to use certified recovery equipment to remove the refrigerant, keep it in approved containers, and dispose of or reclaim it according to regulations.

In practice, this means you must recover the refrigerant before disposal to meet environmental and regulatory requirements, regardless of the type of refrigerant or substitute used.
