Fire Destroys Aircraft Hangar, California <br /> A metal aircraft hangar containing a fixed-wing plane and a glide destroyed when heat from a <br /> fire caused it to collapse. The fire may have been burning for some time when a passerby <br /> discovered it, since the building had fire-detection or—suppression systems. Built on a slab <br /> foundation,the single steel-frame hangar had metal walls, a metal roof,and partition walls that <br /> divided the building into several sections that could be sublet. However,the walls didn't extend <br /> to the ceiling. <br /> Responding to a 911 call at 7:10 p.m.,fire crews arrived seven minutes later to fmd the building <br /> well involved in fire, its metal walls glowing red from the heat and flames venting through the <br /> roof. The incident commander called several other fire departments to help extinguish the fife, <br /> but the hangar and its contents were destroyed. Investigators determined that the fire started <br /> under a wood-frame mezzanine in the hangar,but they were unable to locate the ignition source. <br /> Losses were estimated at$400,000 for the building and$500,000 for its contents. There were no <br /> injuries. <br /> Kenneth J.Tremblay,2004,Online exclusive,"Firewatch",NFPA Journal,Ianuary/February. <br /> Cutting Torch Ignites Airplane Hangar,Nebraska <br /> Work crews using a cutting torch to remove an old overhead door track from an airplane hangar <br /> t started-a fire that smoldered for nearly five hours before it was detected.By that time,the fire <br /> �+ had spread into concealed roof spaces.A 30-mile-per-hour(48-kilometer-per-hour) wind and a <br /> limited water supply hampered extinguishment efforts, and the fire eventually destroyed the <br /> structure and its contents. <br /> The unsprinklered hangar,which was 180 feet(55 meters) long, 120 feet(37 meters)wide, and <br /> 40 feet(12 meters)high,was constructed mainly of wooden bowstring trusses with concrete <br /> buttresses.Metal covered the roof and walls,and there was no fire detection equipment.At the <br /> time of the fire,the structure housed two planes,hazardous materials, and fuel. <br /> The fire department received a 911 call from a passerby and responded at 6:52 p.m.with an <br /> engine,a ladder truck,and an ambulance.The initial attack using two 2 I/2-inch hose lines was <br /> quickly withdrawn to defensive positions, as the fife spread through an 8-foot(2-meter)void <br /> near the roof.Fire crews set up unmanned portable monitors just inside the door,and played <br /> deck guns and hose lines into the burning building. <br /> The extinguishment effort was complicated by a limited water supply.An 8-inch(20-centimeter) <br /> main fed the hydrants, and the amount of water needed to supply the large-diameter nozzles far <br /> outweighed the supply in the system.Additional resources were called, and all companies laid 5- <br /> inch feeder lines from hydrants some distance from the hangar <br /> The hangar roof collapsed at 7:18 p.m., only 26 minutes after the 911 call. <br /> 411110 Occupants told investigators that they originally smelled wood burning about 4:30 p.m., but <br /> thought a coffeepot had overheated.An hour later,the odor was still present,but no one could <br />
