Which statement defines Decommissioning in an asset lifecycle?

• A. The process of removing an asset or facility from service or operation, often involving environmental cleanup and/or returning the site to its original state.
• B. The process of installing new equipment.
• C. The process of commissioning.
• D. A temporary shutdown.

Answer: (A)

Decommissioning is the end-of-life step for an asset where it is permanently removed from service and the site is restored. It involves safely shutting down the system, removing hazards, recovering any refrigerants or hazardous materials, disposing or recycling equipment, and cleaning up the site to return it to its original or an agreed final condition. In the context of flammable-refrigerant refrigeration systems, this also means ensuring refrigerants are recovered, power is isolated, leaks are prevented, and all regulatory and environmental requirements are met. This is different from installing new equipment, which is about bringing something new into service, or commissioning, which is about verifying performance after installation, or a temporary shutdown, which is not permanent.
