What security measures support MMR compliance?

• A. Access controls, surveillance, fencing, inventories, and procedures to prevent theft or loss.
• B. Only signage.
• C. No security measures are necessary.
• D. Public open access to storage areas.

Answer: (B)

Signage as a security measure supports MMR compliance by clearly communicating the rules, access restrictions, and required procedures that everyone handling munitions must follow. Visible notices provide a constant reminder of who may enter areas, what handling steps are required, and how to report issues, reducing ambiguity and guiding everyday behavior. This everyday visibility helps deter mishandling or unauthorized access and makes compliance easier to audit, since posted signs demonstrate that the rules are known and being followed. While other controls like access restrictions, surveillance, fencing, inventories, and formal procedures are important parts of a security program, signs lay the baseline for awareness and consistent adherence across all operations.
