At least one aperture is arranged in a fire cell with connection to the atmosphere, so that when a fire occurs, there is excess pressure (9) within a fire cell. This excess pressure, in combination with fans in the drive arrangement, is restricted to such levels that the risk of combustion gas spreading to other fire cells (2, 3, 4) is eliminated via the common parts (5, 6) of the ventilation system. |
