Texas Wildfires 2011: Season Among Worst In State History


Аmong Soviet and post-Soviet fire-fighting equipment, only the gas-water-quenching still is the world's best.
AGVT (ПСУГВТ-200  АГВТ-150 ) car-gas-water quenching, designed to extinguish the oil and gasfountains, as well as fires at the chemical plants. Empirically determined that the greatest effect is the thread in which 54% water and 46% of the exhaust gases.


Сountries that produce such equipment:
Ukraine, Russia, Hungary
Names of manufactured products:

Мodernization reserves:
With the help of a jet engine can be fed into the flame an inert gases and pieces of dry ice

Еxtinguishing fires in coal mines harder than еxtinguishing gasfountains. In mines the flames takes a large volume. Stream of carbon dioxide from evaporating dry ice at the bottom of the mine could push out the flame. After successfully fighting a fire in a coal mine may  be not enough oxygen for breathing. To continue the rescue operations must be pumped into the mine fresh air with water spray. There are many technologies fire-fighting spraying water in the world. water droplets must be sufficiently dispersed to effectively reduce the temperature. This greatly improves the dampness, and sometimes because of the water film, surfaces become slippery. Sometimes you have to bring sand to sprinkle the slippery surface on your way
Мust be remembered that prolonged high temperatures ( about 50-60 Celsius degree) in the coal mine - a sign of the future explosion, even if the amount of methane in the normal range.

The AI-19IGG-A automobile unit is designated for localization, suppression and prevention of fires in closed spaces, such as mines, tunnels, cable manholes, oil-filling tankers, storerooms. The AI-19IGG inert gas generator mounted on an automobile chassis produces and delivers to a fire area a steam-gas mixture with low oxygen content which hampers burning or inflammation.
The AI-19IGG-A unit and its auxiliary equipment is delivered as a modulus of full factory readiness. For convenience of transporting the steam-gas mixture to a fire area the AI-19IGG inert gas generator is mounted on a rotating platform of an automobile and is furnished with an extensible arrow-like pipeline. In the figure is shown a diagram of possible applications of the AI-19IGG-A unit for suppressing fire in different industrial premises. The maximally possible achievable altitude, at which the steam-gas mixture can be transported, makes up 14 meters.
The normal operation of the AI-19IGG unit is maintained with availability of the following conditions:

altitude above sea level up to, m 3000

ambient temperature, С° -30…+50

air relative humidity, % 80

wind velocity, m/s 20

terrain slope prior to installation, % (degree) 5.2 (3°)
