However, since the beginning of a small number of small fire smoke, not easy to find, once the smoke Dayton, has become a disaster. In the spread of the fire, the smoke filled the ground or in the air are very difficult to determine the true location of fire and fire developments. It is even more difficult at night to identify the location of a fire field based on topographic features. By sight to determine the edge of the fire distribution sometimes great error. It is not uncommon for fire commanders to bung their fighters for unknown circumstances. Fire control first depends on the “fire out”, which is accurate monitoring and control of the fire, timely reporting of the location of fire and fire developments.
