How must refrigerant recovery cylinders be labeled?

Refrigerant recovery cylinders are required to be labeled with the type of refrigerant contained as well as its recovery status to ensure safety and compliance with regulations. This labeling is essential because it provides critical information for technicians handling the cylinders, allowing them to identify the refrigerant type quickly and determine whether it is used, recovered, or remanufactured. Proper labeling helps prevent cross-contamination of refrigerants, enhances safety by minimizing the risk of accidental releases, and ensures adherence to environmental regulations regarding the safe handling and disposal of refrigerants. Failure to label cylinders correctly can lead to dangerous situations and potential legal issues, which is why this specific requirement is in place.
