2006 IBC 412.2.6 Fire Suppression-Aircraft hangers shall be provided with fire suppression by NFPA 409. Exception group II hangars as defined in NFPA 409.
8.9.1.1 (11' Ed.) dictates fire protection based on the criteria in Chapter 4 with additional requirements as noted for 8.9.1.2 as it reads "In addition to the requirements of 8.9.1.1, where hazardous operations...." So I guess in your case the protection criteria in Chapter 7 (Group II Hangers) & Section 5.4.2 would not need to be applied but the protection criteria for a Group III Hangar would still be required. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bob Knight Sent: Thursday, November 11, 2010 8:30 AM To: [email protected] Subject: Group III Aircraft Hanger Good morning forum, We are looking at a Group III hanger. NFPA 409 8.9.1 provides guidance for fire protection when hazardous conditions such as fuel transfer, welding, cutting, soldering, etc... are present, but it provides no guidance as what to do when they are not. In this case none of the conditions 8.9.1 lays out will be present, but the aircraft will have fuel in the fuel tank (no transfer of any kind). Do we default to NFPA 13 or some other fire sprinkler design criteria in 409?
