 (IFEX), in which the water is highly pressurized into a vaporous mist, creating a cooling effect that is more efficient than that of water alone. Some fire engines have been equipped with injectors for mixing foam into the pumped water stream creating a foam solution that is more effective than water alone. Some modern apparatus have included an air pump alongside foam injection to produce a compressed air foam product that further increases the efficiency of the water stream, cutting down dramatically on extinguishing time and water damage.

Turntable ladder

A turntable ladder (TL) is perhaps the best-known form of specialised aerial apparatus, and is used to gain access to fires occurring at height using a large telescopic ladder, where conventional ladders carried on conventional appliances might not reach.

The name is derived from the fact that the large ladder is mounted on a turntable on the back of a truck
Truck
A truck or lorry is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration, with the smallest being mechanically similar to an automobile...

 chassis, allowing it to pivot around a stable base, which in turn allows a much greater ladder length to be achieved. In order to increase its length, the ladder is telescopic. Modern TLs are either hydraulic or pneumatic in operation.

A ladder also can be mounted behind the cab. This is sometimes called "mid-ship" and the arrangement allows a shorter wheelbase for the truck, and also can be more stable in some conditions.

The key functions of a turntable ladder are:
  • Allowing access or egress of firefighters and casualties at height;
  • Providing a high level water point for firefighting (elevated master stream);
  • Providing a working platform from which tasks such as ventilation or overhaul can be executed.


While the traditional characteristic of a fire appliance was a lack of water pumping or storage, many modern TLs have a water pumping function built in (and some have their own onboard supply reservoir), and may have a pre-piped waterway running the length of the ladder, to allow a stream of water to the firefighters at the top. In some cases, there may also be a monitor at the top of the ladder for ease of use. Other appliances may simply have a trackway which will hold a manually run hose reel securely, and prevent it from falling to the ground.
Tower ladder

Some turntable ladders may have a basket (sometimes known as a bucket) mounted at the top of the ladder, as on a hydraulic platform; these are called tower ladders. These appliances can provide a secure place for a firefighter to operate equipment from, and allow multiple people, including rescued persons, to be carried.
Tiller ladder

A tiller ladder, also known as a tractor-drawn aerial or hook-and-ladder truck, is a specialised turntable ladder mounted on a semi-trailer truck
Semi-trailer truck
A semi-trailer truck, also known as a semi, tractor-trailer, or articulated truck or articulated lorry, is an articulated vehicle consisting of a towing engine , and a semi-trailer A semi-trailer truck, also known as a semi, tractor-trailer, or (in the United Kingdom and Ireland) articulated truck...

s for front and rear wheels. This truck is primarily used in the United States, especially in areas with narrow streets that prevent longer rigid-bodied trucks from entering such as San Francisco and Washington, DC. The hook-and-ladder concept started when taller skyscrapers and more city streets became a problem for fire departments. Larger ladders were needed to get to the upper stories of buildings, and the only way to move them was in this format.
Quint/quad

In some areas of the United States, the turntable ladder may be known as a quint
Quint (fire apparatus)

 designed for firefighting use. They have a number of functions, which follow the same principles as the turntable ladder, providing high level access and elevated water pump positions.

Some hydraulic platforms are articulated, which allows the arm to bend in one or more places, giving it the ability to go "up and over" an obstacle (such as a building roof). There are non-articulated platforms, based on standard aerial work platforms, although the most common type is the tower ladder (mentioned above). HPs (articulated or not) may still have a ladder arrangement fitted to the arm, primarily as an emergency measure. In some jurisdictions these can be denoted ladder platforms.

Most HPs are designed to reach a height of around 33 metres (100 feet), although larger models are capable of reaching heights of over 100 metres (328 feet).

Many HPs are fitted with additional equipment in the platform itself, which can include a control panel, lighting equipment, a fixed water outlet or monitor, power outlets or compressed air outlets (allowing the fixing of rescue equipment, such as hydraulic rescue tools

Rescue engine/pumper

A rescue pumper or rescue engine is a purpose-built unit of fire apparatus beyond a typical NFPA Class A rated engine company. The original concept was to marry the capabilities of a heavy rescue squad and that of a class A rated pumper, that is to add 1,000 gpm or greater fire pump and 500 gallons of water. This is a newer concept that first began in the late 1980s and early 1990s.

This first design did not include all the supply hose that is usually carried on a typical engine, but had the tool-carrying capacity of a heavy squad, including extrication equipment and the specialized rescue tools not carried on ladder trucks or engine companies.

The current design is more like a typical fire engine than a true rescue pumper. Today's rescue engine differs from the original unit concept Rescue Pumper, designed by Fire Chief S. E. Politano, which was simply to add more initial firefighting capabilities (onboard water and pumping capacity) to a heavy rescue squad, not bring heavy rescue squad capabilities to an engine company.

.

Wildland or brush trucks are also distinguished from standard engines in that some models offer the ability to pump water while the apparatus is moving. This contrasts with standard engines or pumpers, which use the vehicle's engine to power the pumps, meaning that the vehicle must be stationary while the pump is in operation.

Hazardous materials apparatus

Many fire departments covering large metropolitan areas or those containing many high-risk hazards keep specialist appliances for dealing with hazardous materials

 (HAZMAT). These are of several types, from those used to clean spilled oil on streets and highways, to full decontamination units, designed to clean victims and rescuers of contaminants after an incident.

Some fire departments may deploy a scientific support vehicle where required. Essentially a mobile laboratory, these units can attend a wide range of incidents, including chemical spills and fires, where early on-site scientific analysis and monitoring will speed up the detection process and allow firefighters and other emergency services to provide the correct response for the particular incident.

Logistical support apparatus

or water bowser, is a specialist fire appliance with the primary purpose of transporting large amounts of water to the fireground to make it available for extinguishing operations. These are especially useful in rural areas where fire hydrants are not readily available and natural water resources are insufficient or difficult to exploit.

Most tankers have an on-board pumping system. This pump is often not of sufficient power to fight fires (as it is designed to be attached to a fire engine), but is more often used to draw water into the tender from hydrants or other water sources. In some areas, the tenders are used to pump water during floods, and may be fitted with a heavier duty pump for this purpose. Many tankers are equipped with fast-drain valves on the sides and back of the truck. This allows firefighters to empty thousands of gallons or several cubic meters of water into a portable water tank
Portable water tank

 in just a few seconds.

Most water tenders are designed to carry loads of 1000 US gal (3,785.4 l; 832.7 imp gal) or more. In the U.S., 1,000 U.S. gallons is the requirement in the NFPA standards. Some may carry up to or even upwards of 5000 US gal (4,163.4 imp gal; 18,927.1 l) of water.

Hose layer

In some fire departments, a similar function may be performed by a hose layer, which carries large-capacity high-pressure hose wagons to incidents where hydrants or other water sources are not close enough to the fireground. It will lay out its hose at the nearest hydrant or water source then drive to the fireground with the hose laying off the back; upon arrival it will connect to a fire appliance to supply it with the water needed for the firefighting operations.

Foam tender

Foam tenders carry large amounts of foam to be used at incidents where water is ineffective or cannot be used to tackle a blaze. They may take the form of a tanker, or a truck carrying foam packets or barrels.

Fireboat

Some fire departments that protect a body of water, such as a major city harbor or coastline, may utilise fireboats to combat fires on watercraft and waterfront areas. Such fireboats pump water from under them, so they can theoretically provide water indefinitely. In some places, fire boats are not just designed for firefighting, they can also be used to perform rescue missions, and transport divers and other equipment to the scene.

 (ICAO) has given standards and recommended practices on rescue firefighting categories of civil aerodromes. National aviation authorities may have given even further requirements on aerodrome rescue and fire services.

The rescue fire services are based on a statistical analysis of movements (take-offs and landings) on the airport. The aerodrome category is based on the size of the biggest aircraft taking a movement on the aerodrome. In addition, the number of movements of the critical aircraft is calculated, and the category can be decreased by one if the number of movements is lower than the standard describes. There are also minimum category levels based on, for example, the number of seats in the critical aircraft.

Depending on the airport category, the standards determine the minimum number of rescue firefighting vehicles. In addition, requirements are given on the water and foam capacities, discharge rates for foam solutions, and minimum dry chemical powder (complementary agent) amounts, reserve stocks of fire fighting agents, ability to operate on rough terrain, and acceleration of the air crash tenders. The end of each runway must be reached in a response time of two minutes, and any part of the movement area has to be achieved in a response time not exceeding three minutes.

Aircraft

Fire departments may also deploy airplanes and helicopters to attack fire from the air. Such aircraft are fitted with large tanks that drop water or fire retardant chemicals onto the fire.

Design and construction

Many fire appliances around the world are based on standard truck or lorry models, which are upgraded to the specifications required by the purchasing department. In the United States, a majority of fire trucks are specially designed from the chassis to the cab and body. This has led to the use of the term custom fire truck, as opposed to a commercial chassis and cab.

A fire appliance may undergo modifications such as adjustments for higher durability, removal of any speed limiter, and adjustments for long periods of idling at a higher temperature. This may be accomplished by heavy duty suspensions, brakes, tires, alternator, transmission and cooling systems. It is also usual to upgrade the capacity of the electrical system to accommodate additional electrical and electronic equipment.

Fire appliances have audible and visual warnings, to protect themselves from traffic, and make themselves visible to other units at an incident.

In many countries, use of the audible and visual warnings affords the driver a degree of exemption from road traffic laws (such as the right to exceed speed limits, treat red stop lights as give way etc.) and may also infer a duty on other motorists to move out of the direction of passage of the fire vehicle (or face possible prosecution).

Visual warnings

Visual warnings on a fire appliance can be of two types: either passive or active.

Passive visual warnings

The passive visual warnings involve the use of high contrast patterns. Older vehicles (and those in developing countries) are more likely to have their patterns painted on, whereas modern appliances often carry retro-reflective
Retroreflector

 designs which reflect light from headlights or torches. Patterns include "checker board" (alternate coloured squares, sometimes called "battenburg markings

", named after a type of cake), chevrons (arrowheads, often pointed towards the front of the vehicle if on the side, or pointing vertically upwards if on the rear) or stripes (along the side; these were the first type of retro-reflective devices introduced, as the original retro-reflective material came only in tape form). In some countries, in addition to retro-reflective markings, vehicles are now painted a bright yellow or orange, although in many other countries, red remains the colour for fire engines. In Australia a number of rural fire units are painted white, such as those used by the Country Fire Service

 in South Australia, making them more visible in bushfire conditions.

Another passive marking is the word FIRE, RESCUE or local language variant spelled out in reverse on the front of the vehicle. This enables drivers of other vehicles to more easily identify a fire service vehicle in their rear view mirrors. The appliance may also display a telephone number which may be used to summon assistance, along with the name of the operating department or station identifier.

NFPA 1901 Standards for Automotive Fire Apparatus: 20.4 Aerial Ladder Operating Position
20.4.2 A system that is lighted and marked with labels shall be visible from the operator's position to indicate the elevation, extension, and rated capacities (see sample of boom angle indicator).

Active visual warnings

The active visual warnings are usually in the form of flashing coloured lights (also known as "beacons" or "lightbars"). These flash to attract the attention of other road users as the fire appliance approaches, or to provide warning to motorists approaching a stopped appliance in a dangerous position on the road. Common colours for fire warning beacons are blue and red. The beacons can be made to flash, the original method was to place a spinning mirror which moves around a light bulb, called a "rotating beacon". More modern methods include the use of strobe lights, which are usually brighter, and can be programmed to produce specific patterns (such as a left -> right pattern when parked on the left hand side of the road, indicating to other road users that they should move out away from the vehicle). There is also the more widespread use of LED

Audible warnings

In addition to visual warnings, most appliances are also fitted with audible warnings, sometimes known as siren

 before they can be seen. The first audible warnings were mechanical bells, mounted on the front or roof of the truck. Most vehicles are now fitted with electronic sirens, which can produce a range of different sounds. Fire service driving training often includes the use of different sounds depending on traffic conditions and maneuver being performed. For instance, on a clear road, approaching a junction, the "wail" setting may be used, which gives a long up and down variation, with an unbroken tone, whereas, in heavy slow traffic, a "yelp" setting may be preferred, which is like a wail, but faster.

The speakers for modern sirens can be located in several places on the vehicle, including being integral to the lightbar, or hidden in the grille. Some vehicles may also be fitted with airhorn audible warnings. A number of North American fire departments have returned to the "acoustic" or "air" traditional siren, as its overtones help the public "locate" and avoid the firetruck—the newer electronic signals disperse almost pure electronic sine wave tones, which are hard to locate, especially in city "canyons" of buildings. In Chile, many vehicles are fitted with three types of audible warnings, which are sounded all at once: the classic "air" siren, the electronic "yelp", and the European two-tone air horns (sometimes newer vehicles are fitted with the electronic version of the latter, commonly called "Hi-Lo").

s, whereby the vehicle can be fitted with a short range FM transmitter, set to RDS code 31, which interrupts the radio of all cars within range, in the manner of a traffic broadcast, but in such a way that the user of the receiving radio is unable to opt out of the message (as with traffic broadcasts). This feature is built in to all RDS radios for use in national emergency broadcast systems, but short range units on emergency vehicles can prove an effective means of alerting traffic to their presence, although is not able to alert pedestrians and non-RDS radio users.

Additional equipment

Firefighters may also have a range of additional equipment available to them, which may include:
  • Two-way radio—This is one of the most important pieces of equipment. Many services have moved from traditional UHF/VHF sets, which can be monitored externally, to more secure systems, such as those working on a GSM system, such as TETRA

    —Some fire vehicles can be fitted with video cameras used to record activity. They may also be fitted with sound recording facilities.

  • Ramming pads—These rubberized pads are fitted to the chassis of the appliance, to allow the vehicle to be used as a battering ram, or to push other vehicles off the road in an emergency. One of the uses of ramming pads is to remove a parked car illegally blocking a fire hydrant that is needed by fire crews responding to an emergency.

Crew assignment

Engines are normally staffed with at least three people if possible: an officer, a driver (who usually operates the pump), and a firefighter. Preferably, an engine will carry a second firefighter, to increase effectiveness in safely attacking a fire. In some countries, such as Finland

, an engine carries the unit leader, an engineer, and one or two pairs of firefighters. Since firefighting takes places in a very hot and hostile environment with high risks, fire fighters work as pairs, and at least one more pair of firefighters is needed on scene for the safety and shifting.

In cities of the United States, firefighters are generally deployed into fire companies specializing in certain tasks. Most common are engine companies and ladder, or "truck", companies. In addition, large cities frequently staff rescue companies. By definition, each company is led by an officer (a captain or lieutenant) who commands several firefighters. Staffing of fire companies varies by jurisdiction and frequently by company type. In large cities, fire company staffing may vary from as few as three to as many as six personnel. In suburban and rural areas of the United States, the legal organization to which volunteers belong is usually called a company; one company may operate several pieces of apparatus. Duties of volunteers are often less specialized than those of city firefighters, because it is less predictable who will be available for a given emergency, so more flexibility is needed.

Other departments staff their fire engines as emergency response units. The staged layout of fires stations and apparatus around a city means that a fire engine dispatched from its station may reach a medical emergency call faster than an ambulance coming from a hospital. Therefore, firefighters are trained as EMT

s and paramedics. The usual complement includes 1 fire captain and a number of additional firefighters. The number of additional firefighters depends on the severity of the incidents it will respond to, the capacity of the fire truck in question, the nature of the call for assistance and the personal preference of the fire department. For example, a pumper truck might carry 1 captain, 2 FF/Es (Engineers) and 1 FF/P (paramedic). Both the captain and the engineers are trained as Emergency Medical Technicians.

Many departments staff all of their trucks as medical response units, while some use a mixture. Common units that are medical response units include: Pumper, Rescue, Search & Rescue, and Hazardous Materials Units. The advantage of Medical Response units is well worth the training expenses. 911 medical calls that are responded to by a fire truck places less strain on ambulances and certified first responders, enabling them to focus on more critical patients. The disadvantage includes training for the firefighters as EMTs and paramedics, which happens to be very expensive. Also, medical equipment must be carried by the fire truck, reducing storage space for some firefighting equipment.

, historically known as brigades, and usually organized at county, city, or combined level. These are divided into either commands or areas, in some cases divisions, then stations, which range in size but in almost every instance have at least one pumping appliance. In addition, general purpose engine stations may have specialist vehicles, such as turntable ladders, hydraulic platforms, foam tenders, etc. The number of personnel at a station varies depending on the number of appliances, and whether it is full time, day manned, or retained. Generally, the crew of an average sized pump is around five, but in any case it can be no less than four and no more than six.

 by firefighters and its use was discontinued, and motorized fire engines did not become commonplace until the early 20th century.

For many years firefighters sat on the sides of the fire engines, or even stood on the rear of the vehicles, exposed to the elements. This arrangement was uncomfortable and dangerous (some firefighters were thrown to their deaths when their fire engines made sharp turns on the road), and today nearly all fire engines have fully enclosed seating areas for their crews.

Early pumpers

Early pumpers used cisterns as a source of water. Water was later put into wooden pipes under the streets and a "fire plug" was pulled out of the top of the pipe when a suction hose was to be inserted. Later systems incorporated pressurized fire hydrants, where the pressure was increased when a fire alarm was sounded. This was found to be harmful to the system, and unreliable, and today's valved hydrant systems are kept under pressure at all times, although additional pressure may be added when needed. Pressurized hydrants eliminate much of the work in obtaining water for pumping through the engine and into the attack hoses. Many rural fire engines still rely upon cisterns or other sources for drafting water into the pumps.

Early aerials

Since the late 19th century, means of reaching tall structures have been devised. At first, manually extendable ladders were used; as these grew in length (and weight) these were put onto two large wheels. When carried by fire engines these ladders had the wheels suspended behind the rear of the vehicle, making them a distinctive sight. Before long, the turntable ladder—which was even longer, mechanically extendable, and installed directly onto a fire truck—made its appearance.

In 1905, the first modern fire engine was constructed by Knox Automobile
