What documentation is reviewed annually and cancelled when no longer applicable?

The correct answer is manuals. Manuals are structured documents that provide essential operational instructions, technical guidance, and standard procedures for personnel. They are subject to regular review to ensure that the information remains accurate and relevant to current practices and technologies.

Due to the nature of the information contained in manuals, they must reflect the most up-to-date methods and standards. When a manual is found to no longer be applicable—due to changes in procedures, technology, or organizational restructuring—it is cancelled to prevent confusion and ensure that personnel are not relying on outdated information.

This process of annual review and cancellation of outdated manuals helps maintain operational efficiency and safety, ensuring that all personnel are trained on the latest protocols. Other options such as guidelines, policies, and checklists may have different review processes or may not require regular cancellation upon becoming outdated, making manuals the most suitable choice for this context.
