Aircraft hangars range in value from about $150,000 for small regional bases to millions of dollars for commercial jet airliners to hundreds of millions of dollars for military aircraft and the hangars they’re stored in. What safeguards do you have in place to detect and extinguish fires in your aircraft hangar? Not only do fire protection systems defend the structure and contents of the hangar, but they also protect human life.

Fire Safety Risks in Aircraft Hangars
Regardless of your hangar’s type or size, you’re likely to face these fire safety risks:
- Flammable fuel is stored onboard aircraft.
- Extra gasoline is stored on the premises.
- Maintenance activities such as fuel transfer, welding, spray painting, and torch cutting create hazardous situations.
- Expansive areas promote the fast spread of fire.
- Aircraft bodies and wings obstruct fire suppression nozzles.
Aircraft Hangar Classifications
Hangars vary in size, type, equipment, and the number of aircraft they hold. According to the National Fire Protection Association (NFPA) 409, there are four classifications of aircraft hangars based on these factors. They include:
- Group I hangars – Larger than 40,000 square feet and/or have access doors taller than 28 feet
- Group II hangars – 40,000 square feet or less with access doors 28 feet or shorter
- Group III hangars – 30,000 square feet or less (may be either an open bay hangar or row hangar with multiple units) with access doors 28 feet or shorter
- Group IV hangars – Constructed of a membrane-covered rigid steel frame
Fire Suppression Systems for Aircraft Hangars
The NFPA approves the following systems for fire suppression in aircraft hangars of various classifications:
- Foam-water deluge systems with supplementary foam systems installed beneath aircraft wings (Group I and II)
- Automatic foam system combined with automatic sprinklers (Group I and II)
- Automatic closed-head, foam-water sprinklers (Group II)
- High- or low-expansion foam systems (Group IV)
- Single-interlock or wet pipe pre-action sprinkler system (Group I, II, or IV that only house unfueled aircraft)
Group III hangars usually don’t require automatic fire suppression systems—unless you perform hazardous maintenance activities there. In that case, you should follow the fire protection requirements established for Group II hangars.
Operating Your Aircraft Hangar’s Fire Suppression System Safely
To ensure your fire suppression system functions as intended, make sure to do the following:
- Have installation performed by a qualified, licensed fire protection company, such as United Fire Protection.
- Schedule routine inspections and document all maintenance activities in a logbook. Include the company and the name of the technician along with all services performed.
- Include supplementary fire protection systems as needed, including concentrated foam storage tanks, fire pumps, handheld foam hoses, protection for structural steel columns, and a trench draining system.
