Flame Detection In Aircraft HangersSource: Emerson Process Management, Rosemount Analytical
Whether a commercial or military aircraft hanger, there are always three very important considerations: protection of the structure, protection of it’s contents, and most importantly protection of the technicians and engineers. Commercial aircraft hangers generally incorporate the guidelines outlined the NFPA 409 standard for fire safety, which puts emphasis on the people, then the structure. Military installations instead focus on their people then the aircraft. In either application, the response to a flame event must be extremely fast and accurate in order to protect lives, allow the greatest amount of time to respond, and protect valuable property.
Primary fire risks in these areas include: aircraft fuel spill ignition (through static discharge, electrical malfunction, maintenance activity, heaters or spark) as well as hydraulic fluids, lubricants, and solvents. There is also the potential for the presence of explosive cargo or ordnance under the wings (the highest risk area).
