What should a flight attendant do if they discover a fire on board?

The focus of a flight attendant's response to a fire on board is critical for the safety of everyone. Notifying the captain is essential because the captain needs to be aware of any emergencies to manage the situation appropriately and coordinate with the rest of the flight crew. Utilizing fire extinguishing equipment immediately addresses the fire, while securing the area helps prevent further injury or damage, and maintains a safe environment for passengers and crew. This multi-step approach ensures that the situation is handled efficiently and reduces potential risks, aligning with the established safety protocols that prioritize the well-being of everyone on the aircraft.
