During the formation of a firestorm many fires merge to form a single convective column of hot gases rising from the burning area and strong, fire-induced, radial (inwardly directed) winds are associated with the convective column. Thus the fire front is essentially stationary and the outward spread of fire is prevented by the in-rushing wind. [10]
A very large fire can produce a firestorm, in which the central column of rising heated air induces strong inward winds, which supply oxygen to the fire. Conflagrations can cause casualties including deaths or injuries from burns , trauma due to collapse of structures and attempts to escape, and smoke inhalation .
Towards 5 am, before the firestorm had reached its full intensity, the idea of building a Wassergasse (lit. ' water alley ') was conceived by Rudolf Prescher, lieutenant of the fire brigade. This alley would allow the people to flee their shelters for safer areas of the city.
Also referred to as air attack. The use of aircraft in support of ground resources to combat wildfires, often most effective in initial attack in light fuels. air drop The delivery of supplies or fire retardant from the air. Supplies can be dropped by parachute, while retardant is generally released in a single drop of one or more trails, the size of which is determined by the wind and the ...
A flammagenitus cloud, [1] also known as a flammagenitus, pyrocumulus cloud, or fire cloud, is a dense cumuliform cloud associated with fire or volcanic eruptions. [2] A flammagenitus is similar dynamically in some ways to a firestorm, and the two phenomena may occur in conjunction with each other. However, either may occur without the other.
For weeks smoke from ongoing fires to the west cast a grey haze into the atmosphere, suggesting that dangerous fire weather and extensive grass fires were already occurring upstream of the region ...

3D zone control: The strategy of 3D zone control intended to improve the safety of firefighters operating inside a burning structure.It attempts to safeguard the immediate locality of any space occupied by firefighters in resorting to various defensive actions that (a) confine the fire; (b) remove combustion products safely and effectively; or (c) mitigate dangers in the hot-gas layers.
