What should flight attendants do if they encounter smoke in the cabin?

When flight attendants encounter smoke in the cabin, the appropriate and trained response is to use fire extinguishers and follow emergency procedures as outlined in their training. This is crucial because smoke in the cabin can be indicative of a fire, which can escalate quickly if not addressed properly. Flight attendants are trained to assess the situation, prioritize passenger safety, and take immediate action to control or extinguish the source of smoke. This includes using fire extinguishers effectively and consulting the aircraft's emergency protocols to ensure the safety of all on board.

The other options are not appropriate responses in this situation. Waiting for assistance from the pilot alone could jeopardize passenger safety, as the flight attendants are often the first responders and must act swiftly. Assuming the cabin is safe and continuing with service would ignore the potential dangers posed by smoke, which could escalate into a more serious emergency. Evacuating passengers immediately might not always be the safest or most practical option, depending on the nature of the smoke and the available safe exits. Therefore, taking proactive steps to manage the situation is essential for ensuring the safety and well-being of everyone on the flight.
