What is the appropriate response to a fire in the aircraft cabin?

Using fire extinguishers and notifying the captain is the appropriate response to a fire in the aircraft cabin because it emphasizes the immediate and effective action required in such a critical situation. Fire extinguishers are specifically designed to handle cabin fires, allowing trained personnel to tackle the source of the fire quickly, which can prevent it from spreading and potentially causing more serious consequences. Notifying the captain is essential as they have the authority and knowledge to guide the situation, including making decisions about emergency procedures, diverting the flight if necessary, and ensuring that ground support is prepared once landing occurs.

This approach prioritizes the safety of everyone on board while maintaining control of the situation, as opposed to waiting for ground assistance or evacuating without assessing the situation and addressing the fire directly. Distributing water to passengers would not be effective in managing a fire, and immediate evacuation without addressing the fire could lead to panic and chaos, further compromising safety.
