| | |  fire triangle: Encyclopedia II - Fire fighting - Means to extinguish a fire
Fire fighting - Suppressing the fuel and the energy.
The first method is to remove fuel for the fire such as cutting of the gas and moving combustible objects from the path of the fire. When the activation energy is still present, it is also useful to switch it off; this will not stop a fire, but will help controlling a starting fire and will prevent a new fire to occur.
The first action is thus to "cut off the energies" such as the gas and power supply and switch off the working machines (motors). It is also important to turn off ventilation and air conditi ...

| | | | fire triangle: Encyclopedia II - Firestorm - Firestorms in cities The same underlying combustion physics can also apply to man-made structures such as cities.
Firestorms are thought to have been part of the mechanism of large urban fires such as the Great Chicago Fire, Great Fire of Rome, the Great Fire of London, and the fires resulting from the 1906 San Francisco earthquake and the Great Kanto earthquake.
Firestorms were also created by the firebombing raids of World War II in Hamburg, Dresden, Tokyo, Kassel, Darmstadt, and Stuttgart. (see also: firebombing of Dr ...

| | | | fire triangle: Encyclopedia II - Fire fighting - Appendix : Calculation of the amount of water required to suppress a fire in a closed volume In the case of a closed volume, it is easy to compute the amount of water. Indeed, when the volume is tight, the air can not come in; and the air is necessary for the combustion, the oxygen O2 (pure air contains 21% of O2). Whatever the amount of fuel available (wood, paper, cloth), the combustion will stop when the air becomes "thin", i.e. when there is less than 15% oxygen.
This gives:
the amount of water required to make the atmosphere inert, i.e. to prevent the pyrolysis gases to burn; this is the "vol ...

| | | | fire triangle: Encyclopedia II - Fire fighting - Individual action A starting fire is easy to extinguish: a thimbleful of water can extinguish a match, a bucket of water can extinguish a fire created by a match after one minute; but after a few minutes, tons of water are required. It is thus important to know how to fight a starting fire, but also to know that once it is started, the most effective action is to warn people to evacuate the building (if necessary) and call for help; any other action would be dangerous and harmful as it would delay ...

| | | | fire triangle: Encyclopedia II - Fire fighting - Risks of a fire The first risk that comes to the mind is the heat. Even if a person is not "in" the flames, he/she can be burned by the infrared radiations, the contact with a hot object, by the hot gases (heated air, but particularly water vapour produced by the spraying), and by the smoke (hot particles), which are indeed the most dangerous thing. The firefighters are equipped with personal protective equipment (PPE) that includes fire-resistant clothing and helmets that slow ...
