AbstractA previous publication specified critical areas of high-level vent which, if exceeded, would not allow reduction of the oxygen concentration in buildings to zero. In fact, many building fires will be satisfactorily extinguished if the oxygen concentration is only reduced to about 9 per cent to 15 per cent. In this note it is shown that vent areas may exceed the critical values by a factor of 2 or even 4 under favourable circumstances.
