The Most Common Fire Risks Found in Airport Facilities

Airports are some of the most complex facilities to manage. Unlike traditional commercial properties, airports bring together a wide range of environments, including passenger terminals, aircraft operations, maintenance areas, transportation systems, retail spaces, and critical infrastructure.

Each area has its own operational demands and safety considerations. For airport facility managers, identifying where fire risks exist is an important part of protecting passengers, employees, aircraft, equipment, and ongoing operations.

While every airport has unique challenges, several common risk areas appear across aviation facilities.

Fuel Storage and Fueling Operations

Fueling operations are among the most significant fire risk areas at any airport. Aviation fuel is essential to daily operations, but its storage, transportation, and use require careful management because of its flammable properties and classification as a Class B fire hazard (flammable liquids).

Fuel-related risks can occur throughout multiple areas of an airport environment, including aircraft fueling locations, fuel farms and storage areas, fuel transfer operations, fueling vehicles and equipment, as well as potential spill or leak scenarios. In many cases, these environments also involve electrical systems and equipment, introducing additional Class C fire considerations where energized electrical sources are present.

Because fueling activities often take place near aircraft, runways, taxiways, and other active operational areas, these environments require ongoing awareness of potential hazards.

The combination of combustible liquids, heavy equipment, and constant operational activity makes fuel systems one of the most critical areas for airport fire safety planning.

Aircraft Hangars

Aircraft hangars are designed to accommodate large aircraft and specialized equipment, but their size and daily operations create unique fire safety challenges. These spaces may include aircraft with fuel systems and batteries, maintenance equipment, hydraulic fluids, electrical systems, ground support equipment, and stored materials.

Because hangars support ongoing aircraft maintenance and servicing, changing activities can introduce different fire risks from day to day. The large, open layout of many hangars can also make fire detection, fire alarm monitoring, and risk management more complex.

Maintaining awareness of changing conditions is essential to identifying hazards, supporting response efforts, and protecting both aircraft and personnel.

Maintenance Facilities

Maintenance areas support essential airport operations, but they also introduce hazards due to the types of activities performed.

Aircraft and equipment maintenance may involve hot work activities, welding and cutting, chemical use, battery servicing, mechanical repairs, and the handling of flammable materials.

Temporary work activities, contractors, and changing maintenance schedules can introduce new risks into these environments. Areas that are typically low-risk can quickly become more hazardous when new equipment, materials, or processes are introduced.

Understanding these changing conditions is essential for maintaining awareness of facility risks.

Electrical Rooms and Backup Power Systems

Airports depend on reliable electrical systems to support everything from lighting and communications to security systems and operational technology.

Electrical infrastructure can create fire risks through equipment failures, overloaded circuits, aging components, heat buildup, battery systems, and generator operations. These risks are often intensified in environments with continuous demand and complex power distribution, where even minor issues can escalate quickly if not identified and addressed early through regular inspection and maintenance.

Backup power systems are especially important in aviation environments because they support continued operations during disruptions. These systems help maintain critical functions, but they also introduce additional equipment and maintenance considerations. Sprinkler systems also play a key role in controlling fire risk in these areas and require careful coordination with backup power and other building systems.

Electrical rooms, mechanical spaces, and utility areas are often overlooked because they are not highly visible to passengers, but they remain essential parts of airport fire risk management.

Terminal Concessions and Kitchens

Passenger terminals contain a wide variety of businesses, including restaurants, cafes, and other food service operations. These commercial kitchens introduce potential fire risks due to cooking equipment, heat-producing appliances, grease accumulation, electrical systems, and daily food preparation activities.

Unlike a traditional restaurant environment, airport concessions operate within a larger facility where passenger traffic, security requirements, and continuous operations create additional complexity. Even smaller food service areas require careful consideration because they operate within high-occupancy public spaces where safety and uninterrupted operations are critical.

Baggage Handling Areas

Baggage systems are a critical part of airport operations, moving thousands of pieces of luggage throughout the facility every day. These systems rely on a combination of conveyor equipment, motors, mechanical components, electrical systems, sorting technology, and storage areas to keep baggage moving efficiently.

Because baggage handling operations often occur behind the scenes, they may not receive the same visibility as passenger-facing areas. However, these spaces contain continuously operating equipment and infrastructure that require attention as part of an airport’s overall fire and life safety strategy.

Mechanical failures, electrical issues, equipment malfunctions, and operational changes can all impact risk levels within baggage handling areas, making them an important consideration in airport fire protection planning.

Construction and Renovation Projects

Airports are constantly evolving. Expansions, upgrades, and modernization projects are necessary to meet changing passenger needs and operational demands.

However, construction projects can introduce temporary hazards, including hot work activities, temporary electrical systems, building system changes, construction materials, and altered access routes.

Active construction zones create unique challenges because normal facility conditions may change from day to day.

Coordination between airport operations, contractors, and facility teams is essential when managing these changing environments.

Parking Garages and Transportation Areas

Airport parking facilities support thousands of vehicles every day and present their own set of fire safety considerations. These structures often operate continuously, experience high turnover, and include a wide mix of vehicle types, which can increase overall risk exposure if systems are not properly monitored and maintained.

Potential risks include vehicle fires, electrical vehicle charging equipment, fuel-related hazards, mechanical issues, and limited visibility areas that can delay detection or response in the event of an incident.

As transportation technology continues to evolve, airports must also account for the growing presence of electric and hybrid vehicles, along with the expanding infrastructure required to support them. These changes can introduce new fire protection considerations that may not have been part of original facility designs.

Parking structures may not be part of daily airport operations in the same way as terminals or runways, but they remain a critical component of overall airport safety planning and emergency preparedness.

Understanding Airport Fire Risks

Every airport has different layouts, operations, and challenges. A regional airport may have different risk factors than a large commercial hub, but all aviation facilities share one important need: understanding where hazards exist.

From fueling operations and hangars to terminals and infrastructure systems, identifying potential risks allows facility teams to better understand their environment and prioritize safety efforts.

A thorough risk assessment is the first step in building a safer, more compliant aviation facility, helping teams address vulnerabilities before they impact operations. National Fire & Safety supports airports in identifying these risks and developing proactive fire protection strategies tailored to complex aviation environments.
