Fireworks are another notable cause of fire burns, especially among adolescent males on holidays such as Independence Day in the US. [6] The most common cause of injury by fire or flame in children is touching candle flame. [citation needed] In some regions, such as the western United States, wildfires are responsible for an increase in burn ...
Wildfire prevention programs around the world may employ techniques such as wildland fire use (WFU) and prescribed or controlled burns. [120] [121] Wildland fire use refers to any fire of natural causes that is monitored but allowed to burn. Controlled burns are fires ignited by government agencies under less dangerous weather conditions. [122]
At this time in history fire was viewed as a threat to timber, an economically important natural resource. As such, the decision was made to devote public funds to fire suppression and fire prevention efforts. For example, the Forest Fire Emergency Fund Act of 1908 permitted deficit spending in the case of emergency fire situations. [4]
In the most common type of flame, hydrocarbon flames, the most important factor determining color is oxygen supply and the extent of fuel-oxygen pre-mixing, which determines the rate of combustion and thus the temperature and reaction paths, thereby producing different color hues. Different flame types of a Bunsen burner depend on oxygen supply.
In chaparral communities in Southern California, for example, some plants have leaves coated in flammable oils that encourage an intense fire. [20] This heat causes their fire-activated seeds to germinate (an example of dormancy) and the young plants can then capitalize on the lack of competition in a burnt landscape. Other plants have smoke ...
According to the U.S. Fire Administration, the deaths in the United States that were caused by a fire fluctuated over the past 10 years. The administration recorded the increase of deaths between 2012 and 2021, and concluded an increase of 18% per million. [8] Smoke inhalation injury is the most common cause of death in fire victims.

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.
