What is Fire?
Fire is the exothermic chemical process of rapid oxidation of a substance, releasing heat, light, and numerous reaction products. Flames are created at the ignition point, which is a specific point in the combustion event. The component of the fire that is visible is the flame.
Carbon dioxide, water vapor, oxygen, and nitrogen are the main ingredients in flames. Gases may form plasma if heated to a high enough temperature. The color of the flame and the strength of the fire will vary according to the materials that are burning and any pollutants outside.
What is a Fire Shelther?
When trapped by wildfires, wildland firefighters utilize fire shelters as a final alternative for safety. While a firefighter's life may not be spared in a long-lasting grass fire, a shelter of this type can resist brief flame contact.
Layers of fiberglass, woven silica, and aluminum foil are used to build fire shelters. Its maximum deployed size is 86 inches by 15.5 inches. In the 1950s, Australia is where a fire shelter was originally developed.
The structure consists of two levels. Aluminum foil is laminated with woven silica in the outer layer. Radiant heat is reflected by the foil, while the silica fabric slows heat transfer inside the shelter. Aluminum foil and fiberglass are laminated in an inner layer. Fire shelters can successfully retain breathable air and block radiant heat when used properly. However, they are unable to shield wildland firefighters from ongoing direct flame exposure.
