Which documents should a security guard always carry during duty?

A security guard should always carry identification and a communication device during duty for several important reasons. Identification is crucial as it establishes the guard's authority and legitimacy on the premises. It provides a form of verification for both the guard and any individuals they might encounter, such as the public or law enforcement officials. Additionally, having a communication device, such as a radio or a cell phone, is essential for staying connected with colleagues and dispatch. This allows for rapid communication in case of emergencies or to report incidents, thereby ensuring a quicker response and enhancing overall situational awareness.

Other choices do not fulfill the same level of necessity. Carrying only a notebook may assist in note-taking but lacks the essential elements of authority and communication. Personal belongings are irrelevant to the duties of a security guard while on duty. An extensive set of manuals, while potentially useful for reference, is impractical to carry and does not directly aid in communication or identification during an operational situation. Therefore, the combination of identification and a communication device is vital for effective security operations.
