Advanced Fire Suppression Systems: The Critical Shield Protecting Nassau County’s Aviation Infrastructure
Nassau County’s rich aviation heritage, dating back to the early 1900s when it was dubbed the “Cradle of Aviation,” continues today with modern airports, hangars, and aviation facilities that require sophisticated fire protection systems. From the historic Mitchel Air Force Base to contemporary private jet facilities, aircraft hangars present unique fire suppression challenges that require specialized systems beyond traditional sprinkler systems.
Understanding the Unique Fire Risks in Aviation Facilities
Aircraft hangars pose unique challenges for fire protection as three-sided structures with large open doors and high ceilings that present a unique environment to control smoke and fire. They also house aircraft containing liquid jet fuel with a low flashpoint and maintenance activities that may provide potential ignition sources. While a regional fixed base operator hangar might price out at $150,000 and a commercial jet airliner hangar at a few million, the commercial or military aircraft inside hangars can easily cost hundreds of millions of dollars.
An aircraft fuselage skin can be damaged in as little as 45 seconds after initial contact with fire, so automatic activation can be critical for protection. This rapid timeline makes advanced detection and suppression systems absolutely essential for protecting both aircraft assets and human life.
NFPA 409: The Gold Standard for Hangar Fire Protection
The National Fire Protection Association sets NFPA 409 standard, which “helps safeguard life and property through requirements for the proper construction and fire protection of aircraft hangars used for aircraft storage, maintenance, or related activities”. The extent of water-based fire protection that is needed is based on the classification of the hangar: Group I, Group II, Group III, or Group IV, based on square footage of the largest fire area and the construction type.
NFPA 409 identifies several options for Group I aircraft hangar fire suppression, including a Foam-Water Deluge System. However, recent updates to the standard have provided more flexibility. Following numerous risk-analysis studies, the NFPA determined Group II aircraft hangars do not require firefighting foam systems and removed the proposed requirement, meaning airport businesses can use their own discretion to determine the best fire suppression system, such as a water-based sprinkler and drain system.
Modern Fire Suppression Technologies for Aviation Facilities
Today’s aviation fire suppression systems incorporate multiple technologies to address different fire scenarios:
- Foam Systems: Foam effectively suppresses fires in aircraft hangars through cooling the flame, suppressing vapors, and smothering, making it a common fire suppressant used in aircraft hangars because of its ability to expand and blanket flammable fuel to prevent it from combusting.
- High-Expansion Foam: Overhead wet pipe or preaction sprinkler system plus full-floor coverage from high expansion foam generators covering the entire hangar floor discharging at a rate of 3 cfm/sf, with HEF building up on the hangar floor to a depth of at least three feet.
- Dry Chemical Systems: Aircraft hangars require careful planning and design, as well as a combination of water-based and/or dry-chemical-based fire suppression systems, which can be made simple by installing patented FM Approved and UL Listed dual agent dry chemical fire suppression units.
- Advanced Detection: U.S. military branches have recently specified optical flame detectors as part of the fire protection systems for new military hangar construction, with ongoing discussions about updating engineering criteria to include optical flame detectors or even triple infrared detectors.
Nassau County’s Aviation Fire Protection Landscape
Nassau County’s aviation facilities range from historic sites like the Cradle of Aviation Museum, which houses aircraft in restored hangars, to modern private jet facilities. These aircraft were destined to occupy hangars 3 and 4 of Mitchel Air Force Base which was acquired by Nassau County when the base closed in 1961, with the museum originally opening with just a handful of aircraft in the un-restored hangars in 1980.
Modern facilities like private jet hangars require state-of-the-art fire suppression systems that can respond within seconds. A system that can receive and analyze data from multiple detectors, make error-free decisions and dispatch activation and alarm messages in no more than 12 seconds leaves over 30 seconds for the system to deluge the flame.

The Future of Aviation Fire Protection
Modern hangars and aircraft are now equipped with technologies providing more effective protection from potential ignition sources than ever before. The industry continues to evolve with environmental considerations driving innovation. Many aircraft hangars are protected by fire with a highly effective firefighting foam containing perfluoroalkyl and polyfluoralkyl substances (PFAS), but soon this product may become illegal to be used in a number of states due to its potential negative environmental impact, as demonstrated by a 2019 accidental spill of approximately 50,000 gallons of firefighting foam containing PFAS at a Connecticut airport hangar.
Recent revisions to NFPA 409 allow aircraft hangar owners to take control of their fire protection plans, opting for superior fire suppression solutions such as Encapsulator Agents when needed, providing more environmentally friendly alternatives while maintaining effective fire protection.
Conclusion
Nassau County’s aviation facilities require sophisticated fire suppression systems that can respond rapidly to protect valuable aircraft assets and human life.
