What safety features should recovery cylinders have?

1. Filled above 80% capacity

2. Specifically designed to be refilled

3. Must have only one port

4. Not require testing

The correct answer is: Specifically designed to be refilled

Recovery cylinders are critical for safely storing refrigerants during the recovery process, and it is essential that they have certain safety features. The correct answer highlights that recovery cylinders should be specifically designed to be refilled. This is important because these cylinders need to withstand the pressures associated with the different refrigerants being recovered and reused. They are built to handle the stress of multiple refrigerant cycles, ensuring integrity and safety during filling and storage. Cylinders designed for refilling typically incorporate safety mechanisms, such as pressure relief valves, durable materials, and specific construction methods, which conform to industry standards and regulations. These features minimize the risk of leaks, ruptures, or other hazardous situations that could arise during handling and transport. In contrast, recovery cylinders that are not designed to be reused can present significant safety hazards, potentially leading to catastrophic failures. Thus, the design and construction of the cylinder is crucial for ensuring safe operation in the field.
