What is the Corrections Manual referred to as?

The Corrections Manual is referred to as SECNAVINST M-1640.1. This document serves as a key resource within the Naval Safety Forces, providing guidelines and protocols related to corrections and detention procedures for Navy personnel. The correct choice indicates the specific instruction that outlines critical policies, operational procedures, and safety protocols within correctional facilities under the Navy's jurisdiction.

Understanding the function and significance of the Corrections Manual within the context of Naval operations is vital for personnel involved in law enforcement and security. It encompasses best practices, safety measures, and legal compliance, ensuring that all personnel are trained adequately to handle various situations in a corrections environment.

The other options, while resembling official instruction designations, correspond to different manuals that pertain to other aspects of naval operations and are not related to corrections. This distinction highlights the importance of accurately identifying specific manuals relevant to particular duties or areas of responsibility.
