Refillable refrigerant cylinders should be inspected at least once every five years. However, it's essential to check them regularly for any signs of damage or leakage, as well as to ensure they are properly labeled and maintained according to local regulations. Additionally, cylinders should be visually inspected before each use to ensure they are safe for operation.
Recovery cylinders must be specifically designed for the safe storage of recovered refrigerants and should meet the standards set by the Department of Transportation (DOT). They must be labeled correctly to indicate the type of refrigerant contained within, and they should be equipped with proper pressure relief mechanisms. Additionally, recovery cylinders must be regularly inspected and maintained to ensure their integrity and safety during use.
When transporting cylinders containing used refrigerant, the Department of Transportation (DOT) requires that they be labeled with the appropriate hazard class and markings, including the proper shipping name and UN identification number. Cylinders must be securely packaged to prevent leaks and should be transported in an upright position in a well-ventilated area. Additionally, transporters must ensure compliance with all applicable regulations regarding the handling and disposal of hazardous materials.
