What should flight attendants do when they notice a fault in emergency equipment?

When flight attendants notice a fault in emergency equipment, they must immediately notify the flight deck. This action is crucial for several reasons. First and foremost, the flight deck is responsible for the overall safety and operation of the aircraft, and being alerted to any issues with emergency equipment allows them to assess the situation and determine the best course of action. Additionally, in many cases, having timely information regarding equipment status can affect operational decisions, including whether to proceed with the flight or take additional safety measures.

Responding promptly ensures that any potential safety risks can be managed effectively and that appropriate protocols are followed to maintain passenger safety. It is essential for flight attendants to rely on the training and expertise of the flight deck in such situations rather than attempting to resolve the issue themselves, as their primary function is to ensure passenger safety and comfort, not to perform maintenance tasks that require specific mechanical knowledge. Communicating issues immediately ensures that all necessary precautions are taken without delay.
