What is the proper sequence for a lavatory fire scenario?

• A. Notify crew lead, isolate, use extinguisher if trained, and evacuate if needed.
• B. Ignore it until the flight attendant in charge mentions it.
• C. Call outside authorities immediately without involvement of crew.
• D. Flush the lavatory and continue service.

Answer: (A)

When a lavatory fire starts, take structured, immediate action to contain it and protect everyone on board. The first step is to notify the crew lead so the incident is escalated through the proper chain and the flight deck can be alerted and prepared to respond. Next, isolate the area by closing the lavatory door and keeping others away. This helps limit the fire’s access to oxygen and slows the spread of smoke and heat, reducing risk to passengers and crew. If you are trained to use a fire extinguisher, apply it to suppress the fire at its source, focusing on the type of extinguisher appropriate for a lavatory fire. If the fire cannot be contained or if smoke or heat becomes dangerous, evacuate the area per the crew’s instructions and be prepared for possible diversion or landing. Do not flush the lavatory, and do not continue service or attempt to handle the situation alone by bypassing the established chain of command.
