A fire is a chemical phenomenon that occurs with the presence of three main factors, namely, heat, and varies from one substance to another. Each substance ignites at a certain temperature called the ignition point, the oxygen that is naturally present in the air, and the fuel which is the burning substance, whether wood, paper, , These three factors are called the ignition triangle
Means of fire fighting:
To combat the fire, one of the sides of the ignition triangle should be canceled in what is known as the fire theory
Refrigeration of the fire: in which the heat of burning materials is reduced and often using water; because of its great ability to absorb heat.
Stifling the fire: This prevents oxygen from reaching the fire, by covering it in one of the following ways:
Close the windows and air vents in place of the fire, to reduce the proportion of oxygen, thereby reducing the spread of fire.
Separation of fire from flammable materials, by dynamite flaring, and this method is followed in oil well fires. Covering materials with a foam chemical. Replace oxygen with halogen fumes, or carbon dioxide.
