A security guard typically conducts routine patrols of a designated area to ensure safety and prevent unauthorized access. They monitor surveillance equipment, check locks, and inspect for any signs of suspicious activity or safety hazards. Guards often document their observations in reports and may interact with employees, visitors, or the public to provide assistance or enforce rules. In some cases, they respond to emergencies, contact law enforcement or emergency services when needed, and help maintain order during incidents. Their presence serves both a preventive and responsive role in protecting property, people, and assets.
