What is an essential action a security guard should take when an alarm goes off?

When an alarm goes off, it is essential for a security guard to investigate the cause of the alarm. This action is crucial because alarms can signify a range of issues, including potential security breaches, safety hazards, or emergencies that require immediate attention. By investigating, the security guard can determine the legitimacy of the alarm, assess any risks involved, and take necessary actions, such as alerting law enforcement or emergency services if a real threat is present.

This proactive approach not only helps ensure the safety of people on site but also aids in effective crisis management. Moreover, security personnel are trained to respond to alarms promptly and efficiently, making their investigation vital to maintaining security and safety protocols. The responsibility to investigate reflects the guard's role in ensuring a secure environment and their training to handle emergency situations appropriately.
