Safety for Aviation

Fire Extinguishing Systems for Aviation:
Firecare-PRO TL

Fire extinguishing systems must be available in all fire-hazard areas of the aircraft. While manual fire extinguishers are sufficient in the cockpit and in the passenger compartment, permanently installed fire extinguishing systems must be available in inaccessible places. The extinguishing agents for firefighting depend on these respective fire classes:

  • A: solids and embers such as wood and textiles
  • B: liquid substances such as oils, gasoline, fats, varnishes, tar
  • C: pressurized gases such as methane (CH4), hydrogen (H2), propane (C3H8)
  • D: metal fires such as aluminum and magnesium

Depending on the type of fire, the fire is fought with water (fire class A), powder (fire class A and B), carbon dioxide (which is of limited use because of its harmful effects on living organisms) or halons (halogenated hydrocarbons) whose extinguishing effect is based on decomposing flame heat, to react with the carriers of the combustion reaction and thus stopping it.

The use of CSI fire extinguishing systems prevents expensive emergency landings in the event of battery and dangerous goods fires.

CSI Dangerous Goods Box – automatic fire extinguishing system for cargo holds and cabins

There are specific portable fire extinguishers in the cabin for each of the above mentioned types of fires, whilst there are permanently installed fire extinguishing systems in the inaccessible and fire hazardous zones. These zones include the engine area, the APU area and the cargo holds.

It is mandatory to install fixed fire extinguishing systems in passenger aircraft with cargo holds which are not accessible during flight. Due to the large volume of the cargo compartment, the extinguishing agent supply must accordingly be adequately dimensioned. After smoke warning, the cargo hold is hermetically isolated from the remaining areas. The fire extinguishing system is then triggered.

The CSI Dangerous Goods Box is a patented, automatic fire extinguishing system that operates without the use of pressurized gases and is thus not classified by aviation as being a dangerous good.

The lightweight and sturdy CSi Dangerous Goods Boxes can be individually equipped with up to twelve fire extinguishers. The system puts out all hazardous dangerous goods fires in a targeted manner within seconds and reliably prevents any buildup of toxic gases in the cargo bay.


  • Cargo hold for dangerous goods
  • Cabin for Li-ion and Li-polymer batteries

The advantages at a glance:

  • classification as a non dangerous good
  • automatic fire extinguishing system
  • no external energy source needed
  • free of propellant and compressed gas
  • extinguishes fires within seconds
  • prevents buildup of toxic gases
  • light weight
  • biodegradable extinguishing agent

Use in the passenger cabin

The extinguishing agent in use is biodegradable and can be used in the cabin due to its safe properties to extinguish the ever increasing number of battery fires in the electronic devices of passengers. There are already established general rules regarding the handling of lithium-polymer batteries in aircraft, which was issued as a guideline of the IATA (International Air Transport Association). It recommends the following requirements to the airlines:

  • under 100 Wh: any number of batteries can be carried in your hand luggage
  • 100 – 160 Wh: a maximum of two replacement batteries may be taken along
  • over 160 Wh: transportation only as dangerous goods cargo
