INTERNATIONAL AIRCRAFT SYSTEMS FIRE PROTECTION WORKING GROUP MEETING London, England May 18 -19, 2010 Mike Madden Options to the use of Halon for Aircraft Fire Suppression - Potty Bottle Update
Objective Provide a progress report on revision of Section 4.5, Lavatory Trash Receptacle of FAA report “Options to the Use of Halon for Aircraft Fire Suppression Systems – 2002 Update”
Draft Outline • 4.5 Lavatory Trash Receptacle • 4.5.1 Background • 4.5.2 Water Based and Combination Agents • 4.5.3 Halocarbon and Halocarbon Blends • 4.5.4 Boeing Commercial Airplane Status • 4.5.5 Airbus Commercial Airplane Status • 4.5.6 Other Commercial Airplane Status
Draft Outline 4.5.1 Water-Based and Combination Agents. Water, water/surfactant (e.g., Surfactant Blend A), Dry Chemical/Water Mixtures, and combination agents meet all the above requirements. Water is the most common fire- method (sprinkler, mist). Loaded stream or surfactant blends could improve surface wetting of Class A materials. These are all likely to be more effective on Class A materials than halocarbons. Pacific Scientific is commercializing a lavatory fire extinguisher containing Envirogel
Draft Outline 4.5.4 Boeing Commercial Airplane Status In 2006, Boeing replaced all Halon 1301 bottles used in production lavatory waste compartments with FM-200. Boeing is currently working with the FAA to gain approval to allow the use of FM-200 extinguishers for all models of in-service airplanes.
Summary • Request other airframe manufactures support the revision by providing a similar status for their airplanes. Information should address the following: • Have you switched to a Halon replacement in production? • When did or will the new potty bottles be installed in production airplanes? • What agent is used? • Retrofit/spares engineering status? Has it been completed, if so when? • Please E-mail email@example.com with the information, in time to support Louise's schedule
