ABSTRACT:
A method and device for preventing fire and for extinguishing fire in an enclosed space in which a permanent negative pressure is set, includes fresh air being supplied in a regulated manner to the compartment atmosphere as supply air and exhaust air being discharged from the compartment atmosphere in a regulated manner, and wherein should a fire occur or to prevent a fire, an extinguishing agent which is gaseous under normal conditions is supplied to the compartment atmosphere as the supply air. In order to achieve a relieving of pressure without changing the set negative pressure, or upon a sudden flooding of the space with the gaseous extinguishing agent, the total volume flow of fresh air and/or extinguishing agent supplied to the compartment atmosphere as supply air is at all times less than or equal to the volume flow of the exhaust air discharged from the compartment atmosphere.
