What type of personal equipment might a security guard use?

The correct answer encompasses a range of items that are essential for a security guard's day-to-day responsibilities. Uniforms are important for establishing authority and professional presence, while communication devices such as radios or mobile phones enable guards to stay connected with their team and receive instructions or alerts in real-time. Protective gear, which might include items like vests or gloves, ensures the safety of the guard in various scenarios.

The other options suggest more limited or specialized equipment that might not fully represent the standard gear used by all security personnel. For instance, while handcuffs and tasers are tools for specific situations, they are not universally utilized by all security guards and are reflective of law enforcement rather than general security duties. Focusing solely on protective gear and first aid kits excludes the importance of communication and identification components. Lastly, metal detectors and surveillance cameras are equipment typically associated with facility security measures rather than personal equipment carried by guards themselves.
