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. 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. Fire has been used by humans for cooking, generating heat, light, signaling, and propulsion purposes. The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover. A firefighting system is probably the most important of the building services, as its aim is to protect human life and property, strictly in that order. It consists of three basic parts, A large store of water in tanks, either underground or on top of the building, called fire storage tanks, A specialized pumping system, A large network of pipes ending in either hydrants or sprinklers (nearly all buildings require both of these systems).Engineered Fire Suppression Systems are design specific. Engineered systems are usually for larger installations where the system is designed for the particular application. Examples include marine and land vehicle applications, computer clean rooms, public and private buildings, industrial paint lines, dip tanks and electrical switch rooms. Pre-Engineered Abstract: Fire is one of the important element in nature without which world will not function. Despite of all the benefits still the loss occurred due to fire is unaccountable. Due to the fire incident so much of life, property are damaged heavily. So every step is taken universally to control the fire. Fire occurring is a combination of Oxygen, Fuel, and Heat. Fire extinguishers are used to extinguish the fire. Commercially different types of fire extinguishers are used based on the applications. [1]Most of the accidents occurred due to improper handling of fi...
