In the case of a fire on board, what is the first action a flight attendant should take?

In the event of a fire on board an aircraft, the first action a flight attendant should take is to alert the captain. This is vital because the captain has the ultimate authority and responsibility for the safety of the entire flight, including managing emergencies effectively. Informing the captain enables them to assess the situation promptly, coordinate the appropriate emergency response actions, and communicate with air traffic control if necessary.

While using the nearest fire extinguisher is an important subsequent step in combating the fire, it should be preceded by notifying the captain to ensure that proper protocols and safety measures are followed. Directing passengers to evacuate is typically a later action taken when the situation escalates to a level that requires immediate evacuation, and reporting to other crew members is also important but secondary to ensuring that the command structure is aware of the situation first. Therefore, alerting the captain serves as a crucial first action to establish control and manage the incident effectively.
