White pixels show the high end of the count—as many as 100 fires in a 1,000-square-kilometer area per day. Yellow pixels show as many as 10 fires, orange shows as many as fire fighting design course pdf fires, and red areas as few as 1 fire per day. Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.
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. Depending on the substances alight, and any impurities outside, the color of the flame and the fire’s intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning.
