What is the typical first step in an emergency evacuation procedure?

The typical first step in an emergency evacuation procedure is to alert all occupants and emergency services. This action is crucial because it ensures that everyone in the building is aware of the emergency situation and can begin to evacuate in a timely and organized manner. Informing emergency services is equally important, as it allows them to respond quickly to the situation, providing the necessary assistance and resources needed for an effective response.

Alerting occupants can involve activating alarm systems, making announcements, and using signaling devices. This initial notification helps prevent confusion and panic, guiding people towards the nearest safe exits. Once all occupants are alerted, further steps can be taken, such as conducting headcounts and securing the premises, but the priority is to get everyone informed and moving towards safety. Other options, while significant in the overall emergency response, come into play once the evacuation process is underway.
