Military and commercial aircraft of today are incredibly sophisticated, expensive pieces of equipment. They’re stored in aircraft hangars where you expect them to be safe, but consider this: every craft is filled with flammable fuel, and extra gasoline may also be stored on the premises. Regular maintenance activities introduce several ignition sources to the scene. One wrong move could mean disaster.
Since aircraft themselves create large obstructions, typical fire protection systems may not be adequate. That’s why you need to follow National Fire Protection Association (NFPA) 409, the standard on fire protection for aircraft hangars.
Before you choose the proper fire protection system, you need to determine which aircraft hangar classification your facility falls under. NFPA 409 outlines four categories:
In general, Group I and II hangars used to store and service fueled aircraft can choose from the following fire suppression systems:
Group III hangars don’t normally require fixed fire protection systems, but check with your local building codes to be sure. If you engage in hazardous operations within your Group III hangar (for example, fuel transfer, welding, spray painting and torch cutting), you need to follow the fire protection requirements for Group II hangars.
For Group IV hangars storing fueled aircraft, your options include:
If your Group I, II or IV hangar houses only unfueled aircraft, your options include:
In addition to the fire suppression system itself, you must follow a number of other aircraft hangar fire protection requirements, including but not limited to:
You clearly have many design and installation options to choose from. It’s also important to implement each system properly for compliance purposes. You must weigh these options carefully and choose the most effective, economical and compliant choice possible to protect your high-value aircraft.
Kauffman Co. designs, installs, repairs, replaces and inspects an aircraft hangar foam fire suppression system, including those made by ANSUL. This foam system fights the types of fires that break out in aircraft hangars in accordance with NFPA 409 and local Texas codes. ANSUL’s system is designed to suppress flames in areas with large quantities of flammable liquids, making it the perfect solution for many aircraft hangars.
