What is the first step in handling a fire in the cabin?

The first step in handling a fire in the cabin is to notify the pilot. This is crucial because the pilot needs to be aware of the situation immediately to make informed decisions about the aircraft's safety, including potential emergency landing procedures or adjustments to altitude and speed. The pilot has a broader view of the situation and can coordinate with air traffic control and other emergency services if needed.

Communication with the cockpit is the priority, as the pilot will have access to resources and information that can aid in managing the emergency. Once the pilot is notified, appropriate measures can be taken, and further steps such as using a fire extinguisher or evacuating passengers can be implemented based on the severity of the fire and under the pilot's guidance.

Handling a fire effectively relies on swift communication, ensuring that all necessary personnel are informed and can respond appropriately, thus maximizing the safety of everyone on board.
