Airport fire trucks are often painted in a fluorescent yellow-green hue, which is a distinct colour that is easily perceived by humans due to the sensitivity of our eyes to the yellowish-green part of the visible light spectrum. This colour is recommended by the U.S. Federal Aviation Administration (FAA) as it ensures optimum visibility at all times of the day and in all weather conditions. The colour of airport fire trucks is not always consistent, as it is ultimately decided by the fire departments or airport operators.

What You'll Learn
Airport fire trucks are green for visibility
Airport fire trucks are often painted in a fluorescent yellow-green hue, which is a distinct colour that is not found in nature. This colour is specifically recommended by the US Federal Aviation Administration (FAA) for airport fire trucks because it ensures optimum visibility at all times of the day and night and in varying weather conditions.
The yellow-green colour is also supported by the fact that humans are most sensitive to the yellowish-green part of the visible light spectrum, which is why safety vests are also yellow-green. This is in contrast to the traditional red colour of fire engines, which stems from the history of firefighting when volunteer fire departments had to opt for the cheapest paint colour, which was red.
Today, the colour of fire trucks is often decided by the fire departments or airport operators themselves, and there are still red airport fire trucks in operation. However, the yellow-green colour is becoming more common for airport fire trucks, as visibility is crucial in an airport setting, where fire trucks may need to drive over rough terrain and wreckage to reach an aircraft in an emergency.
The unique colour of airport fire trucks also helps to distinguish them from municipal fire trucks, reflecting the different scenarios and responses that airport emergencies require. Airport fire trucks, also known as ARFF (Aircraft Rescue and Firefighting) trucks, are built for off-road driving and carry larger water tanks and various firefighting agents to address situations like aircraft oil spills and electrical fires.

Green is not the only colour used for airport fire trucks
In Germany, for example, the colour mandated by law for fire trucks used on public streets has changed over the years, evolving from dark red to an orange-red and, most recently, to a retroreflecting orange-red. Similarly, in Brazil, the central government has decided to use red for all fire engines, including airport fire trucks.
The choice of colour for airport fire trucks can also be influenced by local traditions and preferences. For instance, the Swiss have mostly switched to yellow fire engines for visibility reasons, while the San Francisco Fire Department in the United States has adopted green fire engines to enhance visibility and community response.
Additionally, airport fire trucks may be customised to match the corporate design of the airport or the local community. For instance, the PANTHER vehicles at Newcastle Airport in the UK are painted half white and half purple to match the airport's uniform design, while some fire trucks near the University of North Texas are green to represent the university's school colour.
Ultimately, the decision on the colour of airport fire trucks rests with the fire departments or airport operators, who may consider factors such as visibility, tradition, and community preferences when making their choice.

Airport fire trucks are larger than municipal fire trucks
Airport fire trucks are often painted in a fluorescent yellowish-green hue, which is a colour that does not occur in nature and is therefore particularly well-perceived by humans. This colour is recommended by the U.S. Federal Aviation Administration (FAA) for airport fire trucks because it ensures optimum visibility at all times of the day and night and in all weather conditions.
Airport fire trucks, also known as ARFF (Aircraft Rescue and Firefighting) trucks, are larger than municipal fire trucks because they have a different set of requirements and scenarios to deal with. Airport fire trucks do not need to navigate city streets, so their larger size is an advantage as it allows them to carry more water, necessary gear, and equipment. ARFF trucks carry a larger water tank, capable of holding thousands of gallons, because they do not have access to water supplies when the locations of emergencies vary and are uncertain. They also carry various firefighting agents, such as firefighting foam, dry chemicals, and clean agents, which are necessary for dealing with aircraft oil spills and electrical fires.
The larger size of ARFF trucks also allows them to carry up to five personnel, which is important for providing a range of services, including fire containment, fire suppression, medical response, passenger and crew extraction, and mutual aid to local departments near the airport. Additionally, ARFF trucks have great acceleration despite their size and weight, and they are built for off-road driving. They have large, wide tires and long travel suspension, which enables them to navigate through rough terrain, such as the runway space of an airport.
The colour of airport fire trucks can vary depending on the region and the preferences of the fire department or airport operators. While the U.S. market leader, Oshkosh, typically paints its airport fire engine lineup green/yellow, Rosenbauer, a major player in Europe, offers a red lineup. Some airports, such as Toronto-Pearson and Seattle-Tacoma, have PANTHER vehicles that are painted half-white and half-black. Other unique colour schemes include purple and yellow/black.

Airport fire trucks carry more water than municipal fire trucks
Airport fire trucks, also known as ARFF (Aircraft Rescue and Firefighting) trucks, are designed to address the unique challenges posed by airport emergencies. One key difference between ARFF vehicles and municipal fire trucks is that airport fire trucks carry significantly more water.
ARFF trucks are equipped with large water tanks capable of holding thousands of gallons of water, whereas municipal fire trucks typically have smaller water tanks. This difference in water capacity is due to the distinct operational requirements of airport firefighting. Airport emergencies can occur in various locations, and fire trucks may not have immediate access to a water supply. By carrying more water, ARFF trucks can effectively respond to emergencies even in remote areas of the airport.
In addition to their larger water capacity, ARFF trucks are built for off-road driving and can navigate through the rough terrain of airport terminal and runway spaces. They feature a slanted body design and a front bumper that enables them to manoeuvre through ditches and uneven surfaces. The size and weight of ARFF vehicles also contribute to their ability to carry more water and equipment. Their larger dimensions allow for the storage of necessary gear, firefighting agents, and the accommodation of up to five personnel.
The specialised nature of airport firefighting demands that ARFF trucks be equipped with powerful, high-capacity pumps. These pumps enable the projection of water and foam from turrets over long distances, which is crucial for effective firefighting and rescue operations. The combination of large water tanks and high-performance pumps ensures that ARFF trucks can deliver a substantial volume of water or firefighting foam to the scene of an emergency.
The distinct colour scheme of airport fire trucks, often a fluorescent yellowish-green, also sets them apart from municipal fire trucks. This colour choice, recommended by the U.S. Federal Aviation Administration (FAA), optimises visibility during both daytime and nighttime operations, enhancing their overall effectiveness in airport emergency response.

Airport fire trucks carry different firefighting agents
Airport fire trucks are often painted in a fluorescent "yellowish-green" colour, which is a departure from the traditional red of fire engines. This is because the fluorescent colour ensures optimum visibility at all times of the day and night and in varying weather conditions.
There are three primary fire suppressants that an ARFF truck can carry: water, firefighting foam, and dry chemicals. Water is often used for the initial attack response. Firefighting foam is mixed with water and used for fuel spills as it coats surfaces and suppresses fire by cutting off its oxygen supply. Dry chemicals are only used when absolutely necessary as they spread easily and require a thorough cleanup. However, they are useful for suppressing chemical and electrical fires, which are common in industrial settings.
The Federal Aviation Administration (FAA) classifies ARFF trucks into five categories based on the types and amounts of fire suppression agents they carry. ARFF trucks must carry all agents on board since there is often little to no access to fire hydrants, especially in remote areas of the airfield. This is in contrast to municipal fire trucks, which can connect to hydrants to access a greater water supply.
