What is the definition of "Unserviceable"?

The term "Unserviceable" refers specifically to an item that cannot be used due to various reasons, such as damage, defects, expiration of shelf life, or the failure to meet established criteria for functionality and safety. This definition clearly indicates that unserviceable items are those that are no longer fit for their intended purpose and may pose safety risks or operational inefficiencies if used.

Understanding this definition is critical in the context of maritime enforcement operations, where equipment reliability and safety are paramount. Items deemed unserviceable must be effectively identified and removed from service until they are either repaired, replaced, or otherwise brought back to a condition that meets necessary standards. This ensures that maritime enforcement personnel can operate effectively and safely without the risk of relying on faulty equipment.

Other definitions provided in the options suggest varying degrees of usability or potential for service, but they do not accurately capture the complete nature of unserviceable items as defined in this context.
