What must guards maintain while on duty as part of local regulations?

Maintaining a current registration is essential for guards on duty as part of local regulations. This registration typically refers to the necessary licensing or certification that validates a guard's authority to perform their duties in a security capacity. It ensures compliance with state and local laws governing security personnel, which may include background checks, training completion, and adherence to safety standards. This registration serves as proof that the guard is qualified and authorized to provide security services, which is critical for both the guard's credibility and the safety of the environment in which they are working.

Other options, while they may hold importance in different contexts, do not specifically pertain to the recognized requirements for professional conduct and operational legitimacy expected from guards within the regulatory frameworks they operate under.
