Cargo Compartment Water Mist/Inerting System Concept ICAO: “Industry and the scientific community need to redouble their efforts to find suitable replacement agents for halon in civil aircraft. In particular, a halon replacement for cargo compartments is critical. ” Halon replacement fire suppression system utilising NEA from OBIGGS and a water mist system has been shown to pass the Minimum Performance Standard FAA DOT/FAA/AR-TN 05/20 Presentation to Transport Canada November 2008 – Fire & Cabin Safety Research
