3 of 10 The wild fire is dangerous due to its rapid spread and ability to quickly cover vast areas. Hot and dry weather with strong wind gusts turns wild fires into hazardous natural disasters. Once a small fire begins, it can spread at a rate of up to 15 mph, consuming everything in its path. For the decade the average number of wild fires in the United States was 78,550 effecting an area of about 7,000,000 acres and causing millions of dollars in damage annually. According to the National Center for Health Statistics (NCHS) the average number of fire related deaths is about 4,000 each year.
4 of 10 Each side of the triangle represents one of the three ingredients of fire – heat, fuel, and oxygen. When there is not enough heat generated to sustain the process, when the fuel is exhausted, removed, or isolated, or when the oxygen supply is limited, then a side of the triangle is broken and the fire is suppressed.
5 of 10 Commonly used wildfire extinguishing techniques involve fire area localization to prevent fire spreading, and subsequent isolation to allow localized area to be burned out. The most intense firefighting techniques are applied only when fires threaten residential areas, hazardous industrial facilities, and such. Use of water is a common technique to extinguish fires by cooling them down. Also, when water is heated to its boiling point, it converts to water vapor which dilutes the oxygen in the air with water vapor. This oxygen removal can also be done with foam.
6 of 10 The fire blanket is a fabric (cloth) made of nano-modified carbon fiber with high strength-to-weight ratio incombustible material. The properties of carbon fiber such as high tensile strength, low weight, and low thermal expansion make it popular in aerospace, civil engineering, and the military. Carbon fiber heat resistance allows withstanding of temperatures up to several thousand degrees Celsius. When woven into fabric from tiny filament yarn, carbon fiber can be considered as an “incombustible silk”.
