Firefighter:

Firefighters or firemen are rescuers extensively trained primarily to put out hazardous fires that threaten civilian populations and property, to rescue people from car accidents, collapsed and burning buildings and other such situations. The increasing complexity of modern industrialized life with an increase in the scale of hazards has stimulated both advances in firefighting technology and a broadening of the firefighter-rescuer's remit. They sometimes provide emergency medical services. The fire service, or fire and rescue service also known in some countries as the fire brigade or fire department, are some of the emergency services.
Firefighting and firefighters have become ubiquitous around the world, from wildland areas to urban areas, and on board ships.

Firefighting worldwide:

In some countries, including Australia, Canada, Finland, Germany, New Zealand and the United States, there are often paid, or career firefighters working. Additionally, there are volunteer firefighters (who are theoretically unpaid) and retained firefighters (who are paid for the specific time they are on duty, i.e. permanent part-time career firefighters) on call 24 hours a day, 7 days a week. In such countries as the United Kingdom and Ireland, the use of additional retained firefighters is standard. In Portugal, the use of volunteer firefighters is standard, along with career firefighters.
In Australia volunteer brigades which are mostly unpaid rural services (although traditionally they are paid by their employers if called out during working hours).
In Germany, volunteer fire departments are established in every town: even the biggest German city, Berlin, with more than 3.6 million inhabitants, has volunteer firefighters besides a career fire service. In fact, only 100 German cities (most of them are towns with more than 100,000 inhabitants) have a career fire service, called the "Berufsfeuerwehr," but in every one of these cities a volunteer fire service exists, too. In cities with a career fire service, volunteer fire brigades support the career fire service at big fires, accidents and disasters. Many of the so-called volunteer departments (usually in towns with 35,000 to 150,000 inhabitants), except in very small towns and villages, are a mixed service of a core of career firemen who are supported by true volunteer firefighters should the need arise. However, the official title of those departments is nevertheless "volunteer fire service".
The structure in Austria is similar to Germany. There are just six career fire services in Vienna, Graz, Innsbruck, Klagenfurt, Salzburg and Linz. As of 2007, some 4,527 volunteer fire departments, the back-bone of the Austrian fire service, could rely on about 320,000 men and women voluntary firefighters as active members.[1] Fire departments exist in even the smallest villages, where they contribute to community life, usually by organizing fairs and other fund-raising activities. In Venezuela, there are, beside the types mentioned above, University Firefighters. They attend any emergency inside the campus and the zones around; however, their most important job is to develop new technologies in this area, thanks to the high level of education of its members: in the Simón Bolívar University Volunteer Fire Department, around 80% of its members have a university degree or are in the process of obtaining one.
In India municipalities are bound by law to have a fire brigade and participate in a regional fire service. Each city has its own fire brigade. The main functions of firefighting services in India are provision of fire protection and of services during emergencies such as building collapses, drowning cases, gas leakage, oil spillage, road and rail accidents, bird and animal rescues, fallen trees, appropriate action during natural calamities, and so on. Industrial corporations also have their own firefighting service. Each airport and seaport has its own firefighting units.
In Japan, fire services are organized on a city/town/village basis. There are 894 fire headquarters and 3,598 volunteer fire corps. These have a total of 155,000 active career firefighters and 21,000 vehicles with 4,800 fire houses; 920,000 volunteer firefighters share an additional 51,000 trucks.
In Romania, the Romanian General Inspectorate for Emergency Situations is responsible for fire fighting and civil defense.

Goals of firefighting

Aside from the main task of extinguishing fires, the goals of firefighting are (in order) saving lives, saving property, and protecting the environment. Firefighting is an inherently difficult occupation. As such, the skills required for safe operations are regularly practiced during training evolutions throughout a firefighters career. In the United States, the preeminent fire training and standards organization is the National Fire Protection Association (NFPA). Often initial firefighting skills are taught during a local, regional, or state approved fire academy. Depending on the requirements of a department, additional skills and certifications such as technical rescue and Para-medicine may also be taught at this time. Firefighters of the New South Wales Fire Brigades Firefighters work closely with other emergency response agencies, most particularly local and state police departments. As every fire scene is technically a crime scene until deemed otherwise by a qualified investigator, there is often overlap between the responsibilities of responding firefighters and police officers such as evidence and scene protection, initial observations of first respondents, and chain of evidence issues.[citation needed] The increasing role of firefighters in providing emergency medical services also brings firefighters into common overlap with law enforcement. One example of this is a common state law requiring all gunshot wounds to be reported to law enforcement agencies.
Some career (full time, paid) firefighters in North America are represented by the International Association of Fire Fighters.
Fire fighting has several basic skills: prevention, self preservation, rescue, preservation of property and fire control. Firefighting is further broken down into skills which include size-up, extinguishing, ventilation, and salvage and overhaul. Search and Rescue, which has already been mentioned, is performed early in any fire scenario and many times is in unison with extinguishing and ventilation.

Prevention

Prevention attempts to ensure that no place simultaneously has sufficient heat, fuel and air to allow ignition and combustion. Most prevention programs are directed at controlling the energy of activation (heat).

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 addition, a major duty of fire services is the regular inspection of buildings 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.
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 innovative ways such as conducting presentations, distributing safety brochures, providing news articles, writing public safety announcements(PSAs) or establishing meaningful displays in well-visited 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.

Self-preservation

Self-preservation is very critical. The basic technique firefighters use is to know where they are, and to avoid hazards. Current standards in the United States recommend that firefighters work in teams, using a "two-in, two-out" rule whenever in an IDLH (Immediately Dangerous to Life or Health) environment.
Tools are generally carried at all times and are important for not only forcible entry but also for self rescue. 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 gasses. 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), in locating the firefighter in distress.

Firefighters often carry personal self rescue ropes. The ropes are generally 30 feet long and can provide a firefighter (that has enough time to deploy the rope) a partially controlled exit out 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 a 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.
In the United States, 25% of fatalities to firefighters are caused by vehicle accidents while responding to or returning from an incident. Many firefighters are also injured or killed by vehicles while working at an incident (Paulison 2005). However, a large percentage of firefighters also succumb to heart disease, in the line of duty.

Rescue

Rescue operations consist of searching for and removing trapped occupants of hazardous conditions. Animals may also be rescued, if resources and conditions permit. Generally triage and first aid are performed outside, as removal from the hazardous atmosphere is the primary goal in preserving life. Search patterns include movement against room walls (to prevent rescuers from becoming lost or disoriented) and methodical searches of specific areas by designated teams. Unlike a fire control team, a rescue team typically moves faster, but has no hose to follow out to safety through the smoky darkness. A rescue rope may be needed for tethering a team involved in exceptionally dangerous conditions.
Incident commanders also arrange for standby search and rescue teams to assist if firefighters become lost, trapped, or injured. Such teams are commonly, and often interchangeably, known as Rapid Intervention Teams (RIT), or Firefighter Assist and Search Teams (FAST). According to "two-in, two-out", the only time it is permissible for a team of firefighters to enter a burning structure without backup in place outside is when they are operating in what is known as "Rescue Mode". Rescue Mode occurs when firefighters have arrived at the scene, and it is readily apparent that there are occupants trapped inside who need immediate rescue. At such a time, properly equipped firefighters (exercising good judgment tempered by training and experience) may enter the structure and proceed directly to victims in need of rescue, RIT will then be put in place when resources permit.
The Worcester Cold Storage Warehouse fire provides a stark example of disoriented rescuers perishing when their air supply was exhausted during a fruitless primary search and subsequent RIT searches.
Searches for trapped victims are exhaustively detailed, often including searches of cupboards, closets, and under beds. The search is divided into two stages, the primary and secondary. The primary search is conducted quickly and thoroughly, typically beginning in the area closest to the fire as it is subjected to the highest risk of exposure. The secondary search only begins once the fire is under control, and is always (resources and personnel permitting) performed by a different team from that which did the primary search.
Rescue operations may also involve the extrication of victims of motor vehicle crashes (abbreviated MVC). Here firefighters use spreaders, cutters, and hydraulic rams, collectively called hydraulic rescue tools—known better to the public as Jaws of Life—to remove metal from the patient, followed by actually removing the patient, usually on a backboard with collar, and transferring to a waiting ambulance crew in the cold zone. More technical forms of rescue include subsets such as rope rescue, swiftwater rescue, confined space rescue, and trench rescue. These types of rescue are often extremely hazardous and physically demanding. They also require extensive technical training. NFPA regulation 1006 and 1670 state that a "rescuer" must have medical training to perform any technical rescue operation. Accordingly, firefighters involved in rescue operations have some kind of medical training as first responders, emergency medical technicians, paramedics or nurses.

Fire control

Fire control (or fire fighting) consists of depriving a fire of fuel (Reducing Agent), oxygen (Oxidizing Agent), heat and/or the chemical chain reaction that are necessary to sustain itself or re-kindle (also known as the four components of The Fire Tetrahedron). Firefighters are equipped with a wide variety of equipment to accomplish this task. Some of their tools include ladder trucks, pumper trucks, tanker trucks, fire hose, and fire extinguishers. Very frequent training and refresher training is required.
Structure fires may be attacked, generally, either by "interior" or "exterior" resources, or both. Interior crews, using the "two-in, two out" rule, may advance hose lines inside the building, find the fire and cool it with water. Exterior crews may direct water into windows or other openings, or against other nearby fuels exposed to the initial fire. A proper command structure will plan and coordinate the various teams and equipment to safely execute each tactic.

History of fire brigades

The history of organized combating of structural fires dates back at least to Ancient Egypt. Many people put out fires back in biblical times, but whether people did it for a living is unknown. Firefighters were known in the Roman Republic, but only as privately organised and funded groups operating as more of a business than a service. This ad-hoc approach was later revolutionised during the Principate to become the first truly professional firefighting service. Augustus called for the creation of a trained fire guard, paid and equipped by the state. Known as the Vigiles, they were organised into cohorts and also served as a night watch and a city police force. Today, fire and rescue remains a mix of paid, call, and volunteer responders. The UK has the retained fire service, whereby fire fighters are on call with pagers from their homes and/or place of work.
