What is the EPA rule regarding venting during service?

• A. Venting refrigerants is allowed if small
• B. Venting is allowed when system not running
• C. Venting only during daytime
• D. Venting refrigerants is not allowed; recover refrigerant

Answer: (D)

The essential rule is that venting refrigerants to the atmosphere during service is illegal. When you service equipment containing refrigerants, you must remove (recover) the refrigerant with approved recovery equipment and store or process it so it isn’t released. The reason is environmental protection—refrigerants can harm the ozone and contribute to greenhouse warming, and the EPA requires these substances to be recovered, recycled, or reclaimed rather than vented. So venting is not allowed under any common service condition; recovery is mandatory.
