3. Description
A. Portable Fire Extinguishers
The portable fire extinguishers are used to extinguish a fire in the cabin, in the cockpit or in the avionics compartment. There are three different types of portable fire extinguishers. Each type is filled with a different agent, halon, 2-BTP (bromotrifluoropropene) or liquid (water). If a fire occurs, the crew can manually operate the portable fire extinguisher to extinguish the fire.

NOTE: The portable fire extinguishers are installed in different locations in the cabin and in the cockpit. Each location is shown by a placard.
4. Component Description
A. Portable Fire Extinguisher - Halon Agent
The portable fire extinguisher is filled with halon agent and is pressurized with nitrogen. It can be used to extinguish an A, B and C classes of fire. The portable fire extinguisher has two primary components:
The portable fire extinguisher is filled with halon agent and is pressurized with nitrogen. It can be used to extinguish an A, B and C classes of fire. The portable fire extinguisher has two primary components:
- A cylindrical container assembly
- A valve assembly.
(1) The cylindrical container assembly contains the extinguishing agent. The container is metal and is painted red. It has a flat base to let it stand vertically. The container has bonded labels which show identification and information.
(2) The valve assembly is installed on the cylindrical container and controls the release of the extinguishing agent from the container assembly. The valve assembly has:
- A carrying handle
- An operating lever
- A nozzle
- A safety device
- An indicator disk or a pressure gauge.
B. Portable Fire Extinguisher - 2-BTP Agent
The portable fire extinguisher is filled with 2-BTP (bromotrifluoropropene) agent. It can be used to extinguish fire of class 5B:C in the aircraft cabin and cockpit. The portable fire extinguisher has two primary components:

- A carrying handle
- An operating lever
- A nozzle
- A safety device
- A pressure gauge.
C. Portable Fire Extinguisher - Liquid Agent
The portable fire extinguisher is filled with potassium acetate, ethylene glycol and water. It can be used to extinguish an A class fire. The portable fire extinguisher has two primary components:
The portable fire extinguisher is filled with potassium acetate, ethylene glycol and water. It can be used to extinguish an A class fire. The portable fire extinguisher has two primary components:
- A cylindrical container assembly
- A valve assembly.
(1) The cylindrical container assembly contains the extinguishing agent. The container is made from nickel plated brass. It has a flat base to let it stand vertically. The container has bonded labels which show identification and information.
(2) The valve assembly is installed on the cylindrical container after the cylinder has been filled with the extinguishing agent. The primary function of the valve is to control the release of the extinguishing agent from the container assembly. The operating head has:
- A syphon tube assembly
- A cartridge holder
- A carbon dioxide cartridge
- A safety device (locking ring)
- A nozzle
- An operating lever.
5. Operation
NOTE: For detailed information about the use and the data of the portable fire extinguisher, refer also to the label. The label on the extinguisher contains the instructions for use, approval number, details of its weight and the date of the last check.
A. Portable Fire Extinguisher - Halon Agent
During normal conditions the portable fire extinguisher is installed in its holder. The crew can remove the portable fire extinguisher from its holder, remove the safety device and operate it manually. The valve assembly controls the release of the extinguishing agent. When the operating lever is operated, the valve in the valve assembly opens. The pressure in the container then pushes the halon agent up the syphon tube to the nozzle. When the extinguishing agent is released through the nozzle, the pressure in the container decreases. The decreased pressure is shown on the pressure gauge. Or, to show that the portable fire extinguisher was used, the full indicator disk is missing (not installed).
For the correct operation procedure of the fire extinguisher, refer to the bonded identification and data labels.

B. Portable Fire Extinguisher - 2-BTP Agent
During normal conditions, the portable fire extinguisher is installed in its holder. The crew can remove the portable fire extinguisher from its holder, remove the safety device and operate it manually. The valve assembly controls the release of the extinguishing agent. When the operating lever is operated, the valve in the valve assembly opens. The pressure in the container then pushes the 2-BTP agent up the syphon tube to the nozzle.

C. Portable Fire Extinguisher - Liquid Agent
During normal conditions the portable fire extinguisher is installed in its holder. The crew can remove the portable fire extinguisher from its holder, remove the safety device and operate it manually. The crew must turn the cartridge holder clockwise (showed by an arrow on the cartridge holder) to arm the fire extinguisher. This will also break the safety wire. The valve assembly controls the release of the extinguishing agent. When the operating lever is operated, the valve in the valve assembly opens. The pressure in the container then pushes the extinguishing agent up the syphon tube to the nozzle.
