Firefighting is the act of attempting to prevent the spread of and extinguish significant unwanted fires in buildings, vehicles, woodlands, etc. A firefighter suppresses fires to protect lives, property and the environment. Firefighters typically undergo a high degree of technical training. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting.

One of the major hazards associated with firefighting operations is the toxic environment created by combustible materials. The four major risks are smoke, oxygen deficiency, elevated temperatures, and poisonous atmospheres. To combat some of these risks, firefighters carry self-contained breathing apparatus.

The first step in a firefighting operation is reconnaissance to search for the origin of the fire and to identify the specific risks. Fires can be extinguished by water, fuel or oxidant removal, or chemical flame inhibition; though, because fires are classified depending on the elements involved, such as grease, paper, electrical, etcetera, a specific type of fire extinguisher may be required.

The classification is based on the type of fires that the extinguisher is more suitable for. The earliest known firefighters were in the city of Rome. In 60 A. It consisted of 7, people equipped with buckets and axes who fought fires and served as police. In the 3rd century B. As water rose in the chamber, it compressed the air inside, which forced the water to eject in a steady stream through a pipe and nozzle.

In the 16th century, syringes were also used as firefighting tools, the larger ones being mounted on wheels. Typically, men in one of the lines would pass along the full buckets of water toward the fire while in the other line women and children would pass back the empty buckets to be refilled.

In the 17th century the first "fire engines" were made, notably in Amsterdam. Ancient Rome did not have municipal firefighters. Instead, private individuals relied on their slaves or supporters to take action. They would not only form bucket brigades or attempt to smother smaller fires, but would also demolish or raze nearby buildings to slow the spread of the fire.

However, there is no mention of fires being extinguished, rather they were contained and burned themselves out. Ancient Rome did not have an organized firefighting force until the Vigiles were formed during the reign of Augustus.

The first ever Roman fire brigade was created by Marcus Licinius Crassus. Fires were almost a daily occurrence in Rome, and Crassus took advantage of the fact that Rome had no fire department, by creating his own brigade— men strong—which rushed to burning buildings at the first cry of alarm. Upon arriving at the scene, however, the firefighters did nothing while Crassus offered to buy the burning building from the distressed property owner, at a miserable price.

If the owner agreed to sell the property, his men would put out the fire; if the owner refused, then they would simply let the structure burn to the ground. After buying many properties this way, he rebuilt them, and often leased the properties to their original owners or new tenants. Prior to the Great Fire of London in , some parishes in the UK had begun to organize rudimentary firefighting crews.

After the Great Fire, Nicholas Barbon introduced the first fire insurance. In order to reduce insurance costs, Barbon also formed his own fire brigade , and other companies followed suit. By the start of the s, insured buildings were identified with a badge or mark indicating that they were eligible for a company's firefighting services. Buildings not insured with a particular company were left by its firefighters to burn, [10] unless they happened to be adjacent to an insured building, in which case it was often in the company's interest to prevent the fire from spreading.

Steam-powered apparatuses were first introduced in the s, allowing a greater quantity of water to be directed onto a fire; in the early s they were superseded by versions powered by an internal combustion engine. Before , there was no countrywide standard for firefighting terms, procedures, ranks, or equipment such as hose couplings.

In the month of August in with war looking very possible the Fire Service's act of came into effect. This unified Great Britain's fire service and prepared them for the German war machine. During the London Blitz, fire men and 20 fire women , as known during the time period died as a result of heavy bombing, 91 of these perished at the same time defending London.

By the end of the London Blitz, firefighters had lost their lives. Following the war, leaps and bounds came to the fire service striving into the modern era. This included every firefighter being trained with the Mark 4 proto set. And also reverting back too compressed cork helmets. Firefighting improved even more with the introduction of the Dennis fire appliances that remain iconic in the UK to this day.

Sadly, despite the introduction of more advanced firefighting strategies, tactics, and equipment to British firefighting following the blitz, there have been nearly firefighters killed. In January , a fire destroyed many of the colonists' provisions and lodgings in Jamestown, Virginia. Boston , New York City , and Philadelphia were all plagued by fires, and volunteer fire brigades formed soon after such disasters. In , Benjamin Franklin founded the Union Fire Company in Philadelphia, which became the standard for volunteer fire organizations.

These firefighters had two critical tools: salvage bags and so-called bed keys. Salvage bags were used to quickly collect and save valuables, and bed keys were used to separate the wooden frame of a bed often the most valuable item in a home at the time into pieces for safe and rapid removal from the fire. The first American attempt at fire insurance failed after a large fire in Charlestown, Massachusetts in Later in , Benjamin Franklin organized the Philadelphia Contributionship to provide fire insurance, which was more successful.

The Contributionship adopted "fire marks" to easily identify insured buildings. Firefighting started to become formalized with rules for providing buckets, ladders, and hooks, and with the formation of volunteer companies.

A chain of command was also established. A firefighter's goals are to save lives, protect property, and protect the environment. A fire can rapidly spread and endanger many lives, but with modern firefighting techniques, catastrophe can often be avoided.

To prevent fires from starting, a firefighter's duties may include public education about fire safety and conducting fire inspections of locations to verify their adherence to local fire codes. Firefighting requires skills in fire suppression, rescue, and hazardous materials mitigation. Firefighters must also have, or be able to acquire, knowledge of department organizations, operations, and procedures, [4] and the district or city street system [4] they will have to negotiate in order to perform their duties.

They must meet minimum physical fitness standards and learn various firefighting duties within a reasonable period [4]. Specialized areas of operations may require subject-specific training. Full-time career firefighters typically follow a hour shift schedule, although some fire departments work 8 or 12 hour shifts.

Usually, the 24 hour shifts are followed by two days off. In fire fighting, there are also people designated as fire wardens, also known as the chief officer. Their duties vary, some may ensure evacuation of that part of the building for which they are responsible; others may be responsible for fire control in a particular area, direct a crew in the suppression of forest fires, or function as fire patrolmen in a logging area.

The chief officer is in charge of his firefighters during fires or emergencies, and he is expected to command and control the overall situation while effectively combating a fire or other emergency. In addition, he must have extensive knowledge of the city, the location of streets, fire hydrants and fire alarm boxes, and the principal buildings. In certain jurisdictions, civilians can get certified to be a Fire Warden, and some cities require certain types of buildings, such as high rises, to have a certain number of Fire Wardens.

For example, the City of Houston, Texas, requires every tenant in a high-rise to have at least one Fire Warden for every sq. One of the major hazards associated with firefighting operations is the toxic environment created by combusting materials. The four major hazards are: [19]. To deal with such hazards, firefighters carry a self-contained breathing apparatus SCBA; an open-circuit positive pressure system to prevent smoke inhalation.

These are not oxygen tanks oxygen as a powerful fire accelerant would represent a grave risk when combined with virtually anything combustible in the presence of fire but use compressed air in a similar manner to SCUBA diving gear. A firefighter's SCBA usually hold 30 to 45 minutes of air, depending on the size of the tank and the rate of consumption during strenuous activities.

Obvious risks associated with the immense heat generated by a fire, even without direct contact with the flames direct flame impingement , such as conductive heat and radiant heat , can cause serious burns even from great distances. There are a number of comparably serious heat-related risks, such as burns from hot gases e. Prolonged, intense exertion in hot environments also increases firefighters' risk for health-related illnesses, such as rhabdomyolysis.

No PPE, however, can completely protect the user from the effects of all possible fire conditions. Heat can cause flammable liquid contained in tanks to explode violently, producing what is called a BLEVE boiling liquid expanding vapor explosion.

Sufficient heat causes human flesh to burn as fuel, or the water within to boil, leading to potentially severe medical problems. Furthers risks include the occurrences of backdrafts. Backdrafts occur when there is a large amount of oxygen introduced to an oxygen-depleted fire.

Introducing oxygen to a low burning fire can be devastating as it will ignite all of the oxygen along the way. Firefighters need to have extreme communication at all times on the fire ground as one broken window at the wrong time could seriously harm anyone operating on the building.

Depending on the heat of the fire, burns can occur in a fraction of a second. Additional risks of fire are the obscuring of vision due to smoke, potentially causing a fall or disorientation ; becoming trapped in a fire; and structural collapse. The conditions observed in healthy male firefighters are "also apparent found in weightlifters and endurance athletes 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. 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. 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.

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.

The first step in a firefighting operation is reconnaissance to search for the origin of the fire which may not be obvious for an indoor fire, especially if there are no witnesses , to identify any specific risks, and to detect possible casualties.
