Abstract (en)

[origin: EP1550482A1] The firefighting system uses carbon dioxide, nitrogen or some other suitable inert gas to flood a room which is on fire and reduce the oxygen concentration from the normal 21% by volume to below 13.8%. Reignition of flames is inhibited below 13.8% oxygen content. At sea level personnel can breathe inert gas and oxygen mixtures down to 10% oxygen without harm. The flooding phase takes 120 seconds, after which the oxygen level reaches a lower threshold (Unterer Schwellwert) - above 10% - and the gas is turned off. Air may leak in, raising the oxygen level. When it reaches an upper threshold (Oberer Schwellwert) - below 13.8% - the gas is turned on again until the lower level is reached.
