Are there automatic extinguishers located under all the sinks in each lavatory?

• A. No
• B. Yes
• C. Only in some lavatories
• D. Not applicable

Answer: (B)

Aircraft lavatories are equipped with a fixed fire suppression system that includes an automatic extinguisher installed under the sink in each lavatory. This design ensures quick, automatic containment of a fire at its source in that space, even before crew action is possible. Because the system is installed in every lavatory, the correct takeaway is that there are automatic extinguishers under the sinks in all lavatories. Portable extinguishers remain available for manual use, but the automatic under-sink system provides immediate protection specific to each lavatory area.
