When using a graduated charging cylinder, what must be done with any refrigerant vented from the cylinder?

• A. It may be vented to atmosphere.
• B. It must be recovered.
• C. It must be stored for later use.
• D. It must be discarded as waste.

Answer: (B)

All vented refrigerant must be recovered. When you’re using a graduated charging cylinder, any gas that escapes needs to be captured by an EPA-approved recovery device and placed into a recovery or recycling system rather than released to the atmosphere. This protects the ozone layer and climate and keeps you in compliance with environmental regulations. Venting to atmosphere isn’t allowed, and simply storing or discarding the vented refrigerant fails to meet proper handling and regulatory requirements. The goal is to ensure no refrigerant is released during charging or maintenance.
