Conflagration
A conflagration is a large fire. Conflagrations often damage human life, animal life, health, and/or property. A conflagration can begin accidentally, be naturally caused (wildfire), or intentionally created (arson). A very large fire can produce a firestorm, in which the central column of rising heated air induces strong inward winds, which supply oxygen to the fire. Conflagrations can cause casualties including deaths or injuries from burns, trauma due to collapse of structures and attempts to escape, and smoke inhalation. Firefighting is the practice of extinguishing a conflagration, protecting life and property and minimizing damage and injury. One of the goals of fire prevention is to avoid conflagrations. When a conflagration is extinguished, there is often a fire investigation to determine the cause of the fire. Causes and types During a conflagration a significant movement of air and combustion products occurs. Hot gaseous products of combustion move upward, causin ...

Firestorm
A firestorm is a conflagration which attains such intensity that it creates and sustains its own wind system. It is most commonly a natural phenomenon, created during some of the largest bushfires and wildfires. Although the term has been used to describe certain large fires, the phenomenon's determining characteristic is a fire with its own storm-force winds from every point of the compass towards the storm's center, where the air is heated and then ascends. The Black Saturday bushfires and the Great Peshtigo Fire are possible examples of forest fires with some portion of combustion due to a firestorm, as is the Great Hinckley Fire. Firestorms have also occurred in cities, usually due to targeted explosives, such as in the aerial firebombings of London, Hamburg, Dresden, and Tokyo, and the atomic bombing of Hiroshima. Mechanism A firestorm is created as a result of the stack effect as the heat of the original fire draws in more and more of the surrounding air. This dr ...

Firefighting
Firefighting is the act of extinguishing or preventing the spread of unwanted fires from threatening human lives and destroying property and the environment. A person who engages in firefighting is known as a firefighter. Firefighters typically undergo a high degree of technical training. This involves structural firefighting and wildland firefighting. Specialized training includes aircraft firefighting, shipboard firefighting, aerial firefighting, maritime firefighting, and proximity firefighting. Firefighting is a dangerous profession due to the toxic environment created by combustible materials, with major risks are smoke, oxygen deficiency, elevated temperatures, poisonous atmospheres, and violent air flows. To combat some of these risks, firefighters carry self-contained breathing apparatus. Additional hazards include falls — a constant peril while navigating unfamiliar layouts or confined spaces amid shifting debris under limited visibility – and structural collapse t ...

Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ...

Great Fire Of Turku
The Great Fire of Turku ( fi, Turun palo, sv, Åbo brand and russian: Пожар Або) was a conflagration in the city of Turku in 1827. It is still the largest urban fire in the history of Finland and the Nordic countries. The city had burned once before, in 1681. Description The fires started burning on 4 September 1827 in burgher Carl Gustav Hellman's house on the hill slightly before 9 p.m. The house had possibly been lit on fire by sparks flying from the chimney of a neighboring building. The fire quickly swept through the northern quarter, spread to the southern quarter and jumped the Aura River, setting the Cathedral Quarter on fire before midnight. By the next day, the fire had destroyed 75% of the city. Only 25% of the city was spared, mainly the western and southern portions. The fire destroyed the downtown area of Turku, including Turku Cathedral and the main building of the Imperial Academy of Turku, Akatemiatalo, which were badly damaged. The disaster was made ...

Fire Prevention
Fire prevention is a function of many fire departments. The goal of fire prevention is to educate the public on the precautions which should be taken to prevent potentially harmful fires and how to survive these fires in the event that they do occur. It is a proactive method of preventing fire-based emergencies and reducing the damage caused by them. Many fire departments have one or more Fire Prevention Officers, which may also be a routine duty of firefighters. In the general sense of preventing harmful fires, many aspects are discussed in the articles Fire protection and Fire safety. In the United States, national work on best practices is in the Vision 2020 program. Target audiences Students Children are the primary target of fire prevention knowledge. Firefighters will often visit schools and teach students the basics of fire prevention and fire safety, including how to evacuate from a burning building and how to prevent fires by avoiding dangerous activities such as playi ...

Structure Fire
A structure fire is a fire involving the structural components of various types of residential, commercial or industrial buildings, such as barn fires. Residential buildings range from single-family detached homes and townhouses to apartments and tower blocks, or various commercial buildings ranging from offices to shopping malls. This is in contrast to "room and contents" fires, chimney fires, vehicle fires, wildfires or other outdoor fires. Structure fires typically have a similar response from the fire department that include engines, ladder trucks, rescue squads, chief officers, and an EMS unit, each of which will have specific initial assignments. The actual response and assignments will vary between fire departments. It is not unusual for some fire departments to have a pre-determined mobilization plan for when a fire incident is reported in certain structures in their area. This plan may include mobilizing the nearest aerial firefighting vehicle to a tower block, or a ...

Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire(bushfires in Australia, in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

CCTV New Headquarters Fire 20090209
Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring (Videotelephony is seldom called "CCTV"). Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head. Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in public. In ...
