'Gas-Phase
Cooling' - 'New-wave' techniques developed by Swedish fire engineers
Krister Giselsson and Mats Rosander, using innovative 'bursts' of
water-fog, to counter the hazards associated with flashover, backdraft
and smoke-gas explosions. These techniques have been further developed by
firefighters in the UK, USA, Spain, Germany and Australia and are now being
adopted by fire authorities around the world.
1. Gas cooling -
used to cool the gases in the overhead below temperatures that support any
progression to rollover or flashover situations.
2. Inerting - used to create an
'inert' atmosphere in the overhead - one of controlled steam OR suspended water
droplets where no evaporation occurs - to prevent or suppress/mitigate any
likely ignition of these gases in a backdraft or smoke explosion.
3. To extinguish - used to suppress
burning reservoirs of fire gases that have accumulated and are burning off in
geometrical voids such as stairshafts; attics or compartments etc.
