If a security guard discovers a fire, what is the recommended action?

Activating the fire alarm is the most appropriate and recommended action when a security guard discovers a fire. This ensures that the alarm alerts everyone in the vicinity to the danger, enabling a timely evacuation and notification of emergency services. Prompt activation of the fire alarm is crucial, as it drastically increases the safety of all personnel in the building and helps to minimize potential chaos and confusion. Once the alarm is activated, occupants can evacuate in an orderly fashion, following established emergency protocols, while trained professionals can respond to the situation.

Attempting to extinguish the fire themselves can be dangerous, especially if the fire is larger than anticipated or if the guard is not properly trained in fire suppression techniques. Ignoring a small fire poses significant risks, as even small fires can rapidly escalate. Continuing with routine activities would not be responsible, as it disregards the immediate threat posed by the fire and places everyone in the area at risk. Thus, activating the fire alarm is the most effective and responsible action a security guard can take in this scenario.
