While a child fire-setter is usually curious about fire and has the desire to learn more about it, [4] a child pyromaniac has an unusually bizarre impulse or desire to set intentional fires. [6] Pyromania, also known as pathological fire-setting, is when the desire to set fires is repetitive and destructive to people or property. [4]
Most studied cases of pyromania occur in children and teenagers. [5] There is a range of causes, but an understanding of the different motives and actions of fire setters can provide a platform for prevention. Common causes of pyromania can be broken down into two main groups: individual and environmental.
Conversely, fires or portions of a fire that have previously been engaged by firefighters may be treated as fire use situation and be left to burn. All fire suppression activities are based from an anchor point (such as lake, rock slide, road or other natural or artificial fire break). From an anchor point firefighters can work to contain a ...
For example, trees evolved with fire-embracing traits can "sacrifice" themselves during fires. But they also cause fires to spread and kill their less flammable neighbors. With the help of other fire adaptive traits such as serotiny, flammable trees will occupy the gap created by fires and colonize the habitat.
Not only is ADHD the most commonly encountered childhood-onset disorder in neurodevelopment, there is also a high comorbidity rate linking ADHD with other behavioral, emotional and learning problems and disabilities. [6] As a need to obtain a defined population sample due to a lack of funds, Wolraich developed the teacher VADRS.
The successful use of virtual reality simulation in disaster management training initiatives is a popular area for research. It has been found that when trainees are able to participate, both verbally and physically in a training exercise, retention is 90%, in great contrast to a 10% retention rate of what they hear, and 50% retention rate of what they see and hear.
A backdraft (North American English), backdraught (British English) [1] or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and ...
A jet fire, also known as a spray fire if the fuel is a liquid or liquefied gas, is a turbulent diffusion flame of flammable material. [3] The characteristics of a jet fire depend on a number of factors. These include: fuel composition; release conditions; release rate; release geometry; direction; and ambient wind conditions.
