A firefighter (or fire fighter, fireman, or firewoman) is a first responder trained in public safety and emergency response such as firefighting, primarily to control and extinguish fires and respond to emergencies such as hazardous material incidents, medical emergencies, road traffic collisions and other emergencies that threaten life, property and the environment, as well as to rescue persons from confinement or dangerous situations and preserve evidence.
Firefighters may also provide ordinance regulations, safety requirements, and administrative public functions for the communities and areas they are subject to jurisdiction to. Male firefighters are sometimes referred to as firemen (and, less commonly, female firefighters as firewomen).
The fire department, also known in some countries as the fire brigade or fire service, is one of the three main emergency services. From urban areas to aboard ships, firefighters have become ubiquitous around the world.
The skills required for safe operations are regularly practiced during training evaluations throughout a firefighter's career. Initial firefighting skills are normally taught through local, regional or state-approved fire academies or training courses. Depending on the requirements of a department, additional skills and certifications may also be acquired at this time.
Firefighters work closely with other emergency response agencies such as the police and emergency medical service. A firefighter's role may overlap with both. Fire investigators or fire marshals investigate the cause of a fire. If the fire was caused by arson or negligence, their work will overlap with law enforcement. Firefighters may also provide some degree of emergency medical service (EMS).

Duties
Fire suppression
A fire burns due to the presence of three elements: fuel, oxygen and heat. This is often referred to as the fire triangle. Sometimes it is known as the fire tetrahedron if a fourth element is added: a chemical chain reaction which can help sustain certain types of fire. The aim of firefighting is to deprive the fire of at least one of those elements. Most commonly this is done by dousing the fire with water, though some fires require other methods such as foam or dry agents. Firefighters are equipped with a wide variety of equipment for this purpose that include ladder trucks, pumper trucks, tanker trucks, fire hose, and fire extinguishers.
See also Fire suppression for other techniques.
When fire departments respond to structure fires, the priorities are life safety, incident stabilization, and property conservation. When the first fire department arrives on-scene, crews assess the fire to determine the degree of risk and most appropriate response strategy, including offensive or defensive tactics from in or outside. Ultimately, the incident commander is responsible for determining strategy.
While structure fires can sometimes be limited to small areas of a structure, wider collateral damage due to smoke, water and burning embers is common. Crews may need to force entry to gain access into the structure. Utility shutoff (such as gas and electricity) is a priority for arriving fire crews. Some structures may require additional training and specialized firefighting tactics. For example, row house fires require specific tactics to decrease risks.
Buildings that are made of flammable materials such as wood are different from building materials such as concrete. Generally, a "fire-resistant" building is designed to limit fire to a small area or floor. Other floors can be safe by preventing smoke inhalation and damage. All buildings suspected to be or on fire must be evacuated, regardless of fire rating.
Structure fires may be fought from the interior and/or exterior. Interior crews may extend fire hose lines inside the building, find the fire and cool it with water. Exterior crews may direct water into windows and other openings, or at any surrounding fuel at risk of igniting.
Rescue
Firefighters rescue persons from confinement or dangerous situations such as burning buildings and crashed vehicles. Complex, infrequent situations requiring specialized training and equipment include rescues from collapsed buildings and confined spaces. Many fire departments, including most in the United Kingdom, refer to themselves as a fire and rescue service for this reason. Large fire departments, such as the New York City Fire Department and London Fire Brigade, have specialist teams for advanced technical rescue. As structure fires have been in decline for many years in developed countries such as the United States, rescues other than fires make up an increasing proportion of their firefighters' work.
Emergency medical services (EMS)
Firefighters frequently provide some degree of emergency medical care. In some jurisdictions first aid is the only medical training that firefighters have, and medical calls are the sole responsibility of a separate emergency medical services (EMS) agency. Elsewhere, it is common for firefighters to respond to medical calls. The impetus for this is the growing demand in medical emergencies and the significant decline in fires.
In such departments, firefighters are often certified as emergency medical technicians in order to deliver basic life support, and more rarely as paramedics to deliver advanced life support. In the United Kingdom, where fire services and EMS are run separately, fire service co-responding has been introduced more recently. Another point of variation is whether the firefighters respond in a fire engine or a response car.
Hazardous materials
Fire departments are usually the lead agency that responds to hazardous materials incidents. Specialized firefighters, known as hazardous materials technicians, are trained in chemical identification, leak and spill control, and decontamination. Specific procedures and equipment are needed to address fire at a property where hazardous materials are being used or stored.
Fire prevention
Fire departments frequently provide advice to the public on how to prevent fires in the home and work-place environments. Fire inspectors or fire marshals will directly inspect businesses to ensure they are up to the current building fire codes, which are enforced so that a building can sufficiently resist fire spread, potential hazards are located, and to ensure that occupants can be safely evacuated, commensurate with the risks involved.
Fire suppression systems have a proven record for controlling and extinguishing unwanted fires. Many fire officials recommend that every building, including residences, have fire sprinkler systems. Correctly working sprinklers in a residence greatly reduce the risk of death from a fire. With the small rooms typical of a residence, one or two sprinklers can cover most rooms. In the United States, the housing industry trade groups have lobbied at the State level to prevent the requirement for fire sprinklers in one or two family homes.
Other methods of fire prevention are by directing efforts to reduce known hazardous conditions or by preventing dangerous acts before tragedy strikes. This is normally accomplished in many ways such as conducting presentations, distributing safety brochures, providing news articles, writing public safety announcements (PSA) or establishing displays in high traffic areas. Ensuring that each household has working smoke alarms, is educated in the proper techniques of fire safety, has an evacuation route and rendezvous point is of top priority in public education for most fire prevention teams in almost all fire department localities.
Fire investigators, who are experienced firefighters trained in fire cause determinism, are dispatched to fire scenes in order to investigate and determine whether the fire was a result of an accident or intentional. Some fire investigators have full law enforcement powers to investigate and arrest suspected arsonists.
Occupational health and safety
Direct risks
To allow protection from the inherent risks of fighting fires, firefighters wear and carry protective and self-rescue equipment at all times. A self-contained breathing apparatus (SCBA) delivers air to the firefighter through a full face mask and is worn to protect against smoke inhalation, toxic fumes, and super heated gases. A special device called a Personal Alert Safety System (PASS) is commonly worn independently or as a part of the SCBA to alert others when a firefighter stops moving for a specified period of time or manually operates the device. The PASS device sounds an alarm that can assist another firefighter (firefighter assist and search team (FAST), or rapid intervention team (RIT), in locating the firefighter in distress.
Firefighters often carry personal self-rescue ropes. The ropes are generally 30 feet (9.1 m) long and can provide a firefighter (that has enough time to deploy the rope) a partially controlled exit out of an elevated window. Lack of a personal rescue rope is cited in the deaths of two New York City firefighters, Lt. John Bellew and Lt. Curtis Meyran, who died after they jumped from the fourth floor of a burning apartment building in the Bronx. Of the four firefighters who jumped and survived, only one of them had a self-rescue rope. Since the incident, the Fire Department of New York City has issued self-rescue ropes to their firefighters.
Heat injury is a major issue for firefighters as they wear insulated clothing and cannot shed the heat generated from physical exertion. Early detection of heat issues is critical to stop dehydration and heat stress becoming fatal. Early onset of heat stress affects cognitive function which combined with operating in dangerous environment makes heat stress and dehydration a critical issue to monitor. Firefighter physiological status monitoring is showing promise in alerting EMS and commanders to the status of their people on the fire ground. Devices such as PASS device alert 10–20 seconds after a firefighter has stopped moving in a structure. Physiological status monitors measure a firefighter's vital sign status, fatigue and exertion levels and transmit this information over their voice radio. This technology allows a degree of early warning to physiological stress. These devices are similar to technology developed for Future Force Warrior and give a measure of exertion and fatigue. They also tell the people outside a building when they have stopped moving or fallen. This allows a supervisor to call in additional engines before the crew get exhausted and also gives an early warning to firefighters before they run out of air, as they may not be able to make voice calls over their radio. Current OSHA tables exist for heat injury and the allowable amount of work in a given environment based on temperature, humidity and solar loading.
During debris cleanup
Once extinguished, fire debris cleanup poses several safety and health risks for workers.
Many hazardous substances are commonly found in fire debris. Silica can be found in concrete, roofing tiles, or it may be a naturally occurring element. Occupational exposures to silica dust can cause silicosis, lung cancer, pulmonary tuberculosis, airway diseases, and some additional non-respiratory diseases. Inhalation of asbestos can result in various diseases including asbestosis, lung cancer, and mesothelioma. Sources of metals exposure include burnt or melted electronics, cars, refrigerators, stoves, etc. Fire debris cleanup workers may be exposed to these metals or their combustion products in the air or on their skin. These metals may include beryllium, cadmium, chromium, cobalt, lead, manganese, nickel, and many more. Polyaromatic hydrocarbons (PAHs), some of which are carcinogenic, come from the incomplete combustion of organic materials and are often found as a result of structural and wildland fires.
Safety hazards of fire cleanup include the risk of reignition of smoldering debris, electrocution from downed or exposed electrical lines or in instances where water has come into contact with electrical equipment. Structures that have been burned may be unstable and at risk of sudden collapse.
Standard personal protective equipment for fire cleanup include hard hats, goggles or safety glasses, heavy work gloves, earplugs or other hearing protection, steel-toe boots, and fall protection devices. Hazard controls for electrical injury include assuming all power lines are energized until confirmation they are de-energized, and grounding power lines to guard against electrical feedback, and using appropriate personal protective equipment. Proper respiratory protection can protect against hazardous substances. Proper ventilation of an area is an engineering control that can be used to avoid or minimize exposure to hazardous substances. When ventilation is insufficient or dust cannot be avoided, personal protective equipment such as N95 respirators can be used.
Long-term risks
Firefighting has long been associated with poor cardiovascular outcomes. In the United States, the most common cause of on-duty fatalities for firefighters is sudden cardiac death, accounting for approximately 45% of on duty US firefighter deaths. In addition to personal factors that may predispose an individual to coronary artery disease or other cardiovascular diseases, occupational exposures can significantly increase a firefighter's risk. Historically, the fire service blamed poor firefighter physical condition for being the primary cause of cardiovascular related deaths. However, over the last 20 years, studies and research has indicated the toxic gasses put fire service personnel at significantly higher risk for cardiovascular related conditions and death. For instance, carbon monoxide, present in nearly all fire environments, and hydrogen cyanide, formed during the combustion of paper, cotton, plastics, and other substances containing carbon and nitrogen. The substances inside of materials change during combustion, and their by-products can interfere with the transport of oxygen in the body. Hypoxia can then lead to heart injury. In addition, chronic exposure to particulate matter in smoke is associated with atherosclerosis. Noise exposures may contribute to hypertension and possibly ischemic heart disease. Other factors associated with firefighting, such as stress, heat stress, and heavy physical exertion, also increase the risk of cardiovascular events.
During fire suppression activities a firefighter can reach peak or near peak heart rates which can act as a trigger for a cardiac event. For example, tachycardia can cause plaque buildup to break loose and lodge itself inside heart or blood vessels causing myocardial infarction, also known as a heart attack. This along with unhealthy habits and lack of exercise can be very hazardous to firefighter health.
Cancer risk in the U.S. fire service is a topic of growing concern. Recent studies suggest that due to their exposure on the fireground, firefighters may be at an increased risk for certain types of cancer and other chronic diseases. Additionally, large international studies generally support the finding from U.S. studies that firefighters have elevated rates of cancer, with some variation by cancer site.
A 2015 retrospective longitudinal study showed that firefighters are at higher risk for certain types of cancer. Firefighters had mesothelioma, which is caused by asbestos exposure, at twice the rate of the non-firefighting working population. Younger firefighters (under age 65) also developed bladder cancer and prostate cancer at higher rates than the general population. The risk of bladder cancer may be present in female firefighters, but research is inconclusive as of 2014. Preliminary research from 2015 on a large cohort of US firefighters showed a direct relationship between the number of hours spent fighting fires and lung cancer and leukemia mortality in firefighters. This link is a topic of continuing research in the medical community, as is cancer mortality in general among firefighters.
Types of coverage and workload
In a country with a comprehensive fire service, fire departments must be able to send firefighters to emergencies at any hour of day or night, to arrive on the scene within minutes. In urban areas, this means that full-time paid firefighters usually have shift work, with some providing cover each night. On the other hand, it may not be practical to employ full-time firefighters in villages and isolated small towns, where their services may not be required for days at a time. For this reason, many fire departments have firefighters who spend long periods on call to respond to infrequent emergencies; they may have regular jobs outside of firefighting.
Whether they are paid or not varies by country. In the United States and Germany, volunteer fire departments provide most of the cover in rural areas. In the United Kingdom and Ireland, by contrast, actual volunteers are rare. Instead, "retained firefighters" are paid for responding to incidents, along with a small salary for spending long periods of time on call. The combined fire services of the United Kingdom retain around 18,000 retained firefighters alongside their wholetime colleagues. In both the UK and Ireland retained firefighters make up the majority of active firefighting personnel. Their training, qualifications, and range of possible deployments, are all comparable to wholetime firefighters. Retained firefighters are required to live or work within a set radius of their assigned fire station - in the United Kingdom this is usually 1 mile (1.6 km), and in Ireland 2 miles (3.2 km).
Firefighting around the world
A key difference between many countries' fire services is what the balance is between full-time and volunteer (or on-call) firefighters. In the United States and United Kingdom, large metropolitan fire departments are almost entirely made up of full-time firefighters. On the other hand, in Germany and Austria, volunteers play a substantial role even in the largest fire departments, including Berlin's, which serves a population of 3.6 million. Regardless of how this balance works, a common feature is that smaller urban areas have a mix of full-time and volunteer/on-call firefighters. This is known in the United States as a combination fire department. In Chile and Peru, all firefighters are volunteers.
Another point of variation is how the fire services are organized. Some countries like the Czech Republic, Israel and New Zealand have a single national fire service. Others like Australia, the United Kingdom and France organize fire services based on regions or sub-national states. In the United States, Austria, Germany and Canada, fire departments are run at a municipal level.
Singapore and many parts of Switzerland have fire service conscription. In Germany, conscription can also be used if a village does not have a functioning fire service. Other unusual arrangements are seen in Denmark, where most fire services are run by private companies, and in France, where two of the country's fire services (the Paris Fire Brigade and the Marseille Naval Fire Battalion) are part of the armed forces; similarly, the national fire service of Monaco is part of the Military of Monaco and maintains an armoury of sidearms for use by firefighters during civil defence operations.
Another way in which a firefighter's work varies around the world is the nature of firefighting equipment and tactics. For example, American fire departments make heavier use of aerial appliances, and are often split between engine and ladder companies. In Europe, where the size and usefulness of aerial appliances are often limited by narrow streets, they are only used for rescues, and firefighters can rotate between working on an engine and an aerial appliance.
A final point in variation is how involved firefighters are in emergency medical services.
Communication and command structure
The expedient and accurate handling of fire alarms or calls are significant factors in the successful outcome of any incident. Fire department communications play a critical role in that successful outcome. Fire department communications include the methods by which the public can notify the communications center of an emergency, the methods by which the center can notify the proper fire fighting forces, and the methods by which information is exchanged at the scene. One method is to use a megaphone to communicate.
A telecommunicator (often referred to as a 000 Operator in Australia) has a role different from but just as important as other emergency personnel. The telecommunicator must process calls from unknown and unseen individuals, usually calling under stressful conditions. He/she must be able to obtain complete, reliable information from the caller and prioritize requests for assistance. It is the dispatcher's responsibility to bring order to chaos.
While some fire departments are large enough to utilize their own telecommunication dispatcher, most rural and small areas rely on a central dispatcher to provide handling of fire, rescue, and police services.
Firefighters are trained to use communications equipment to receive alarms, give and receive commands, request assistance, and report on conditions. Since firefighters from different agencies routinely provide mutual aid to each other, and routinely operate at incidents where other emergency services are present, it is essential to have structures in place to establish a unified chain of command, and share information between agencies. The U.S. Federal Emergency Management Agency (FEMA) has established a National Incident Management System. One component of this system is the Incident Command System.
All radio communication in the United States is under authorization from the Federal Communications Commission (FCC); as such, fire departments that operate radio equipment must have radio licenses from the FCC.
Ten codes were popular in the early days of radio equipment because of poor transmission and reception. Advances in modern radio technology have reduced the need for ten-codes and many departments have converted to simple English (clear text).
Ranks
Many firefighters are sworn members with command structures similar to the military or police. They do not usually have general police powers (although some firefighters in the United States have limited police powers, like fire police departments), though certain fire safety officials (such as fire marshals or fire safety inspectors) do possess extensive police powers in connection with their work of enforcement and control in regulatory and emergency situations. In some countries fire fighters carry, or have access to, firearms, including some US fire marshals, and the Corps des Sapeurs-Pompiers of Monaco which is a military unit providing civilian fire cover.
The nomenclature of firefighting varies from country to country. The basic unit of firefighters is known as a "company" in many countries, including the United States, with its members typically working on the same engine. A "crew" or "platoon" is a subdivision of a company who work on the same shift. In British and Commonwealth fire services the firefighters of each station are more typically organised around a "watch" pattern, with several watches (usually four) working on a shift basis, as a separate "crew" for each engine or specialist appliance at that station.

History
Although people have fought fires since there have been valuable things to burn, the first instance of organized professionals combating structural fires occurred in
ancient Egypt. Likewise, fire fighters of the Roman Republic existed solely as privately organized and funded groups that operated more similarly to a business than a public service; however, during the Principate period, Augustus revolutionized firefighting by calling for the creation of a fire guard that was trained, paid, and equipped by the state, thereby commissioning the first truly public and professional firefighting service. Known as the Vigiles, they were organised into cohorts, serving as a night watch and city police force in addition to their firefighting duties.
The earliest American fire departments were volunteers, including the volunteer fire company in New Amsterdam, now known as New York. Fire companies were composed of citizens who volunteered their time to help protect the community. As time progressed and new towns were established throughout the region, there was a sharp increase in the number of volunteer departments.
In 1853, the first career fire department in the United States was established in Cincinnati, Ohio, followed four years later by St. Louis Fire Department. Large cities began establishing paid, full-time staff in order to try to facilitate greater call volume.
City fire departments draw their funding directly from city taxes and share the same budget as other public works like the police department and trash services. The primary difference between municipality departments and city departments is the funding source. Municipal fire departments do not share their budget with any other service and are considered to be private entities within a jurisdiction. This means that they have their own taxes that feed into their budgeting needs. City fire departments report to the mayor, whereas municipal departments are accountable to elected board officials who help maintain and run the department along with the chief officer staff.
Fundraisers
Funds for firefighting equipment may be raised by the firefighters themselves, especially in the case of volunteer organizations. Events such as pancake breakfasts and chili feeds are common in the United States. Social events are used to raise money and include dances, fairs, and car washes.
