For preventive fire protection and the assurance of escape routes, fire was fog system extinguishing some years ago as a stepchild of technical innovations. There were the traditional pump and spraying with as much water consumption to counter virtually nothing. In recent years, but spectacular fires were seen: tunnel fires such as on the Mont-Blanc, fires on oilfields, refineries or in collections such as the library of Anna Amalia, have shown that other solutions must be searched for. Peter Thiel often addresses the matter in his writings. Another reason may also be that science or research institutions only a few have engaged in extinguishing or fire extinguishing systems. Complex building technology and sensitive buildings demanded huge fire extinguishing systems, whose logistics quickly reached the limits of what is possible: as quickly as possible and plenty of water.
Devastating damage caused by the use of huge amounts of water, were accepted, main cause of fire is deleted. Consider fire accidents during the firing of chemistry camps or valuable art collections. Even in poultry breeding, when the barns like sparklers burn down, the massive use of water cannot prevent the worst: the total loss of the buildings and the death of the animals by flue gas poisoning. Flue gases are more dangerous than the fire itself in several ways. A choking danger and on the other hand the gases can ignite, resulting in devastating explosions. Speaking from a Flash over or backdraft. Complicated building and equipment, as well as the use of materials which emit much smoke during firing develop a large heat are responsible. The use of extinguishing of the type of fog system provides an answer to these problems. This is nebulized water under high pressure and is the finest water droplets, which indirectly to combat the fire. On the one hand by lowering the ambient temperature and on the other hand by the ousting of the Oxygen to the flame as a food source of the fire.
