What is the role of a security officer during a fire alarm?

The role of a security officer during a fire alarm is primarily to ensure the safety of individuals by directing them to evacuate calmly. In situations where a fire alarm sounds, it is crucial for security personnel to facilitate an orderly evacuation to minimize confusion and panic. By guiding individuals to exit the building in a calm and efficient manner, the officer helps to ensure that everyone can safely leave the premises while also facilitating accounting for all personnel once outside.

The other options are not appropriate responses in a fire emergency. Ignoring the alarm poses a risk to individuals' lives and undermines the seriousness of a fire threat. Evacuating only people one trusts can lead to chaos and prevent others from getting the necessary assistance to escape, while investigating the source of the alarm can be highly dangerous and distracts from the immediate need to evacuate. In emergency situations, especially those involving potential fire threats, the priority must always be safety and immediate evacuation.
