Which of the following is a primary duty of a security guard?

The primary duty of a security guard is to protect property and people. This responsibility encompasses a wide range of tasks, including monitoring surveillance equipment, patrolling designated areas, and responding to potential threats or incidents. A security guard serves as a deterrent to crime by their mere presence and actively engages in promoting a safe environment for both employees and visitors. This core mission aligns with the foundational role that security guards play in ensuring safety and security in various settings, such as private businesses, public events, and residential properties.

Other options, while related to the field of security or public safety, do not define the primary role of a security guard. Conducting legal investigations typically involves a more specialized skill set often associated with law enforcement. Serving as a police officer in emergencies requires specific training and authority that guards do not possess, as they are not sworn law enforcement officials. Managing public relations can be part of a broader organizational role but is not a fundamental duty of a security guard, whose focus remains centered on safety and security.
