Abstract (en)

[origin: EP1312392A1] To extinguish a fire in a tunnel (2), e.g. a road tunnel, the site of the fire is isolated by curtains (6,8) on a fire detection signal to give a zone (14) for action. An inert gas floods the zone through flow openings from an external gas supply (31), to reduce the oxygen volume to an inert level. Smoke and fumes are extracted by suction (25) without affecting the inert level. A control unit (23) is linked to sensors to assess the oxygen content in the zone e.g. a smoke detector (5) and oxygen monitor (22), and set the flow of fire extinguishing gas accordingly.
