Ignition Component
The Ignition Component (IC) is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. It is a component of the NFDRS-National Fire Danger Rating System. Ignition Component (IC) (A component of the NFDRS National Fire Danger Rating System (NFDRS) is used in the United States to provide a measure of the relative seriousness of burning conditions and threat of wildfires. Background John J. Keetch, a fire researcher in the southeast, wrote that "One ...-National Fire Danger Rating System) The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to 100 on days when the weather is dry and windy. Theoretically, on a day when the ignition component value is 0 a single firebrand will not start a Wildland fire requiring suppression action. A value of 50, there is a 50% ...

NFDRS
National Fire Danger Rating System (NFDRS) is used in the United States to provide a measure of the relative seriousness of burning conditions and threat of wildfires. Background John J. Keetch, a fire researcher in the southeast, wrote that "One of the prime objectives of the National Fire Danger Rating System (NFDRS) is to provide as accurate a measure as possible of the relative seriousness of burning conditions and thereby, NFDRS can serve as an aid to fire control programs." In 1954 there were eight different fire danger rating systems in use across the United States. Better communication and better transportation were beginning to make mutual assistance agreements between fire control agencies more practical than in the past. State compacts, and in the case of the United States government, federal government, interagency and interregional agreements were bringing fire control teams together from widely separated areas of the county. It became necessary to establish a nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
