Who is responsible in a plant to assure refrigerant cylinders are within the hydrostatic test dates?

The responsibility for ensuring that refrigerant cylinders are within the hydrostatic test dates falls primarily on the owner of the plant. This is because the owner is ultimately accountable for compliance with safety regulations and standards associated with the operation of the facility. Proper maintenance and adherence to safety protocols regarding refrigerant handling are crucial for preventing accidents and ensuring the safety of personnel and the environment.

While other personnel, such as the operating engineer, plant manager, or chief engineer, may play significant roles in monitoring and operating equipment or managing daily operations, the overarching responsibility for compliance and ensuring that regulations are met lies with the owner. This aligns with the understanding that ownership entails not only the financial aspects of the operation but also the duty to maintain a safe working environment.
