What protocol should the in-charge person follow at the facility when emergency vehicles arrive?

The protocol for the in-charge person when emergency vehicles arrive is to assist in controlling the crowd. This is crucial because maintaining safety and order is a primary responsibility during emergencies. By controlling the crowd, the in-charge person can ensure that emergency responders have immediate access to the scene, which can be critical for effective management of the emergency situation. Additionally, directing patrons and bystanders can help prevent panic, reduce confusion, and allow for a clear path for emergency vehicles, thereby facilitating a more effective response.

While it may seem reasonable to direct patrons to leave or close entrances, these actions could lead to chaos and impede the movement of emergency personnel. Requesting vehicles to park far from the scene, while potentially helpful, does not directly address the immediate need for crowd control and could create additional safety concerns if patrons begin to panic or disperse unpredictably. Therefore, assisting in controlling the crowd is the most appropriate action to ensure a swift and efficient emergency response.
