During a fire while taxiing, what is the role of the cabin crew who sees the fire first?

In the scenario of a fire while taxiing, the primary responsibility of the cabin crew member who first detects the fire is to ensure that critical information is communicated quickly and efficiently to the flight deck. By pressing the interphone and informing the captain, the crew member is acting to initiate the appropriate emergency procedures as dictated by the airline's standard operating protocols.

This action is crucial because it allows the flight crew to assess the situation more effectively and determine the proper course of action, which may include preparing for an evacuation or coordinate with ground personnel for emergency response. Immediate communication with the captain ensures that all necessary resources and responses are mobilized promptly.

In this context, alerting passengers or taking physical action such as putting on fire gloves comes after notifying the captain, as those actions rely on the captain's direction during an emergency situation. Therefore, informing the captain is a fundamental step that can facilitate a coordinated and effective response to ensure the safety of all on board.
