1. General
The lavatory fire-extinguishing system is installed in each lavatory service cabinet. The lavatory fire-extinguishing system discharges its extinguishant automatically when heat activates it. Any fire in the waste is kept within the confines of the metal waste-paper bin. An inert gas floods the lavatory service cabinet and extinguishes the fire. Each lavatory fire-extinguishing system has an extinguisher bottle which is self-actuated.

- A fill port with a fill valve,
- A mounting bracket,
- A discharge tube with a fusible plug,
- A pressure gage,
- An identification label.
The container is charged with the extinguisher agent through the fill valve in the fill port. The extinguisher agent also pressurizes the container. The pressure gage is installed on the fill port after the container is charged.
The identification label bonded to the container shows:
- The part number,
- The serial number,
- The date of manufacture,
- The extinguisher agent type,
- The total weight of the extinguisher.
4. Operation
The lavatory fire-extinguishing system is completely automatic and self-contained. A fire or overheat condition opens the release mechanism.
When the temperature in the waste paper-bin area is approx. 79 DEG.C (174.20 DEG.F) the fusible material in the tip of the discharge tube melts. The lavatory fire extinguisher then discharges completely within 3 to 15 s. Each unit weighs 0.454 kg max. It stores and discharges 100 to 130 g of Halon 1301 into the waste paper bin to extinguish the fire.
