Q: Explain the fire principals of wildland fires. And how their behavior differs from structure fires.
The basic fire principals consist of five principals that go into fire behavior. Principal one is the fire triangle or Tetrahedron. The fire triangle consists of having heat, fuel, and oxygen. Removing one of these elements from the triangle and the fire will eventually die out. Principal two is method of heat transfer. Therefore, if heat is transfer from direct contact, liquid or air. A fire of some sort could arise. Methods such as convection, conduction, and radiation. Which is known to be the number one cause of any fire exposure. Principal three in stages and fire growth. This talks about the stages of a fires lowest point of ignition …show more content…
Principal five is the last of the basic principles. Flashover. A flashover is the point at which all or any combustible materials reach their ignition temperature. How do these principals apply to wildland fires? Easy A wildland fire is any fire that is not taking place inside a structure facility, typically in the wildlands. Wildland fires at almost in any case uses elements of the fire triangle. Once the fire is ignited, the fire uses some sort of direct contact or radiation as in method two to spread out amongst the area. Once the fire has spread, it goes through a series of stages from it hottest flame point to its natural decay While in in its decaying process this time could be very critical due to a flashover. In wildland fires flashover could easily become initiated. Wildland fire uses air or oxygen to radiate its heat causing a major eruption. Although all principals are involved. Structure fires differ in examples as Thermal layering. In structure fires, thermal layering typically has three different layers. Extreme heat, superheated gases and moderate heat. In a structure fire, the ceiling is where the extreme heat lives pushing and trapping all oxygen down below and flames searching for a way
