Group I aircraft hangars are those that have a hangar access door height of 28 feet or greater or a single fire area in excess of 40,0002ft. To generate the foam in the quantities needed, a combination of Ansul Jet-X 15 and 20 high-expansion foam generators was the answer. The hangar fire protection project was led by architect-engineers Frankfurt Short Bruza (FSB), Oklahoma City; sprinkler design specialist Security Fire Protection (SFP), Memphis, Tenn.; and Tyco Fire Suppression & Building Products (FS&BP), Marinette, Wis. The overhead foam/water deluge sprinkler system uses low-expansion foams to blanket the fuel spill. Other challenges that factored into the final design included the possibility of maintenance platforms obstructing foam discharge and sloping floors that could allow foam to drain away from its coverage area. High-expansion foam suppresses the fire by using more air and creating a large volume of foam to protect the hangar. xref Fire suppression foam is made up of foam concentrate, water, and air that mixes together to create a blanket of foam. For example, NATA estimates the incremental cost for a foam fire suppression system in a general aviation hangar ranges from $200,000 to $500,000 above a standard fire system. � , �BP.0�� 0000002794 00000 n 0000025090 00000 n Traditional smoke and heat detection systems are intended to provide protection for the hangar structure.
