Where is the fixed halon fire extinguisher discharge nozzle located?

The fixed halon fire extinguisher discharge nozzle is strategically located in the lavatory waste bin. This placement is significant because it addresses the specific fire risks associated with improperly disposed materials in that area, such as flammable items. By situating the nozzle in the lavatory waste bin, the design ensures that any fire that may potentially start in that confined space can be quickly detected and suppressed with halon, which is effective in extinguishing fires without causing significant collateral damage.

The other options do not specifically target areas with higher risks of fire due to the nature of the materials stored. The cabin overhead bin typically contains passenger luggage and is not as focused on fire risk management, while the galley, although it has cooking facilities that can pose fire risks, is handled through other means of fire suppression. The cockpit, being a controlled environment with different types of fire safety measures, does not require a fixed halon discharge nozzle in the same way the lavatory does.
