Abstract
Fire fighting is the act of attempting to prevent the spread of and extinguish significant unwanted fires in buildings, vehicles, woodlands, etc. A fire fighter suppresses fires to protect lives, property and the environment. One of the major hazards associated with fire fighting operations is the toxic environment created by combustible materials. The four major risks are smoke, oxygen deficiency, elevated temperatures, and poisonous atmospheres. Additional hazards include falls and structural collapse that can exacerbate the problems entailed in a toxic environment. To combat some of these risks, fire fighters carry self-contained breathing equipment The first step in a firefighting operation is reconnaissance to search for the origin of the fire and to identify the specific risks. Fires can be extinguished by water, fuel or oxidant removal, or chemical flame inhibition There are four elements needed to start and sustain a fire and/or flame. These are a reducing agent (fuel), heat, an oxidizing agent (oxygen), and a chemical reaction. A fire can be extinguished by taking away any of the four components.In this scientific report, we present a brief background in the field of firefighting by introducing some chapters discussing fire, systems used to suppress fire, documentations included in the contracting fire projects and finally a case study Also universal standards like NFPA and FM Global has been followed in this report.
