Abstract:
The invention relates to the use of a gas or liquid spraying curtain, which is produced by spraying non-combustible gases or liquids, for diluting and/or flushing out clouds of combustible gases, the density of which does not exceed the density of air, from enclosed spaces having one or a plurality of outer openings, and to a method for diluting and/or flushing out clouds of combustible gases, the density of which does not exceed the density of air, from enclosed spaces having one or a plurality of outer openings, characterised in that a gas or liquid spraying curtain is produced by spraying non-combustible gases or liquids at at least one outer opening, which curtain dilutes the cloud of combustible gases situated in the enclosed space and carries it in the direction of the at least one outer opening and thus flushes it out.
