fire
Fire is a chemical phenomenon that occurs with the presence of three basic factors, namely heat, and it differs from one substance to another. Every substance ignites at a certain temperature is called the ignition point, oxygen that is naturally available in the atmospheric air, and fuel, which is the burning material, whether it is wood, paper, or fabrics. These three factors are called the ignition triangle.
Fire fighting means
To fight a fire, one of the sides of the ignition triangle must be canceled in what is known as the extinguishing theory, through:
- fire cooling: In it, the temperature of the burning materials is reduced, and it is often done using water. Because of its great ability to absorb heat.
- fire stifle: In it, oxygen is prevented from reaching the fire, by covering it by one of the following means:
- Close windows and air openings in the fire place, to reduce the oxygen content, and thus limit the spread of the fire.
- Separate fires from flammable materials, by blasting them with dynamite, and this method is used in oil well fires.
- Covering flammable materials with a foamy chemical.
- Substitution of oxygen with halogen vapors, or carbon dioxide.
- starve the fire: This is done by limiting flammable materials in the vicinity of the fire using one of the following means:
- Keep flammable materials, such as alcohol, furniture, papers, and oil products away from heat.
- Keeping the burning material itself away from flammable materials. For example, when one of the factory machines catches fire, it is better to withdraw this machine and remove it from the factory by one of the available methods to protect the rest of the assets in it.
- Dividing the burning material into small sections so that it becomes a group of small fires that can be controlled, but one must beware of the risk of combustion in this method, and that these parts reach other flammable materials.
Fire protection
Firefighting is not limited to extinguishing a fire after it ignites, but rather preventing its occurrence from the beginning, by:

- Training individuals on how to deal with fire, and using simple extinguishing tools, such as: carbon dioxide cylinders, as a small act of one of them may prevent major disasters from occurring, and training them on how to protect themselves from fires.
- Place fire extinguishing tools in clear and easy-to-reach places.
- Study the causes of fires and beware of them, such as:
- Unsafe storage of flammable materials.
- electrical contact.
- Leaving flammable materials in places with high temperatures.
- Leave the fireplace burning, or throw lit cigarettes at flammable material.
