Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Fireboats responding to the conflagration aboard the Deepwater Horizon rig in the Gulf of Mexico on April 21, 2010. Fire management is the process of planning, preventing and fighting fires to protect people, property and the forest resource. The initial priority is rescuing any occupants that may be in a burning building. In rural areas water-tank trucks are usually needed, thus the time factor becomes even more critical. But the Forest Service doesn’t – and can’t – do it alone. The strategy charts the future of fire management, and includes measures to mitigate hazards and improve fire preparedness, response and recovery capabilities. So we look for ways to manage it to play its role, for instance, by igniting prescribed fires. In recent decades, Canadian researchers have greatly expanded our knowledge of wildland fire. These tools help fire managers make better decisions about how and where to allocate firefighting resources. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. For decades, the Forest Service has done just that when it came to wildland fires. Areas where federal government agencies are responsible include national parks and military bases. Buildings are designed to separate and enclose areas, so that a fire will not spread; to incorporate fire-prevention devices, alarms, and exit signs; to isolate equipment and materials that could cause a fire or explode if exposed to fire; and to install fire-extinguishing equipment at regular intervals throughout a structure. These include heat-sensitive devices, which are activated if a specific temperature is reached; a rate-of-rise detector, which is triggered either by a quick or a gradual escalation of temperature; and smoke detectors, which sense changes caused by the presence of smoke, in the intensity of light, in the refraction of light, or in the ionization of air. A forest fire is unenclosed and freely spreading combustion that consumes the natural fuels of a forest—i.e., duff, grass, weeds, brush, and trees. Prescribed burning is also used to improve wildlife habitat or meet other resource management objectives. This stabilization work begins before the fire is out and may continue for up to a year. Wildfire suppression is a range of firefighting tactics used to suppress wildfires.Firefighting efforts in wild land areas require different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Our editors will review what you’ve submitted and determine whether to revise the article. Wildland fires, insects, and disturbances, Canadian Wildland Fire Information System, Canadian Forest Fire Danger Rating System. Ablative water, made by mixing water with additives, forms a dense, heat-absorbing blanket. Updates? For enquiries, contact us. For much of the 20th century, putting out fires (known as fire suppression) was the goal. Our scientists study fire behavior and the effects of fire on ecosystems and society, as well as offer management options. Increasingly, Canadians realize that it is not economically possible or ecologically desirable to eliminate all wildland fires. In the United States a study conducted over a 10-year period found that the most frequent type of fire was electrical (23 percent of all fires); other causes of fire included tobacco smoking (18 percent), heat caused by friction in industrial machinery (10 percent), overheated materials (8 percent), hot surfaces in such devices as boilers, stoves, and furnaces (7 percent), burner flames (7 percent), and combustion sparks (5 percent). Just as fire is an integral part of the forest, fire management is an integral part of forest management. 3. For fire suppression hand-operated fire extinguishers must be provided, but many buildings have a separate piping system to provide…. To reduce the impact and possibility of fire, the building codes of most cities include fire safety regulations. Rehabilitation and restoration is a long-term process that focuses on repairing infrastructure and natural resource damages caused by the fire. Burning only occurs in the area of the perimeter of the ellipse. Thus, gradually, according to their culture, their ... TECHNIQUES 81 Manual undergrowth clearing 81 Corrections? Fire management is a big responsibility, and firefighting can be an expensive proposition. Traditional methods of fire prevention are not proving effective and it is now essential to raise public awareness on the matter, particularly among those people who live close to or in forested areas. Also, several satellite-based systems have been proposed for forest fire monitoring. Dry chemicals are used to extinguish electrical fires or burning liquids, while dry powder is utilized to put out such burning metals as magnesium and phosphorus. The modelling tools range from hourly predictions of fire growth in forest stands, to assessments of the fire-susceptibility of landscapes over several fire seasons or even over multiple years. A typical method of fire fighting is the over-and-under system. By the 1970s, recognition of fire’s ecological benefits had grown. Precedence is then given to any location from which the fire may spread to a neighbouring structure. This information and insight are giving forest managers a range of tools for assessing fire danger, predicting fires and responding as necessary. After some wildfires, the Forest Service may need to implement rehabilitation and restoration activities. An attitude shift. This article was most recently revised and updated by, https://www.britannica.com/technology/fire-prevention-and-control, Drexel University - Fire Prevention and Control, Fire prevention - Student Encyclopedia (Ages 11 and up). We still suppress fires, especially if they threaten people and communities, but we understand that fire has a role in nature – one that can lead to healthy ecosystems. States Department of Low-priority sites are generally wilderness parks and remote forests of limited economic value—although protection of rare habitat, culturally significant areas and similar values will influence suppression decisions. Other important resources for fire managers are programs designed to encourage individuals, businesses and communities to become involved in fire management. Forest managers sometimes use prescribed burning to get rid of built-up fuel loads in forested areas. Bush, grass, and forest fires are frequently fought using the same equipment that is used on structural fires. Besides the fire alarms that are triggered by people, there are many automatic devices that can detect the presence of fire. The fire flanks found to the right and left of the wind direction spread noticeably slower than those in the direction of the wind – the so called fire front or hot spot. Canadian attitudes to fire have changed markedly over the years. Agriculture, significant wildland fire potential outlooks, White Cap Wilderness Fire Study - 45th Anniversary (VIDEO), Wildland Fire Fuel Treatment, Restoration and Rehabilitation (VIDEOS), Strategic Planning, Budget And Accountability, Recreation, Heritage And Volunteer Resources, Watershed, Fish, Wildlife, Air And Rare Plants. Steam is used to control fire in confined areas, while inert gas is employed to extinguish gas, dust, and vapour fires. “Wet” water, formed by the addition of a chemical that reduces surface tension, can be used in a clinging foam to protect the exterior of a structure near the source of a fire. Forest Service firefighters respond to a significant number of those, either because they are burning on National Forest System land or because they are providing assistance to another federal, tribal, state or local partner. National Predictive Services products include weekly and monthly significant wildland fire potential outlooks, intelligence reports that are produced daily or weekly depending on wildfire activity, and annual reports. You will not receive a reply. Large fires are responsible for the greatest amount of area burned in Canada and they pose the highest risk to Canadians’ property, health and safety. Until after World War I little official attention was given to fire prevention, because most fire departments were concerned only with extinguishing fires. The most common of these is the fire engine, equipped with hoses, ladders, water tanks, and tools.
