Arrangement for reducing harmful effects from fire and/or explosion comprising wall elements that are placed in adjacent relationship to one another to form a continuous wall. The element are adapted, when an explosion occurs, to open the area towards the surroundings until the pressure in the area is balanced in relation to the surroundings. Thereafter the elements return to their closed state to enclose the area in relation to the surroundings, preventing air from the surroundings from entering the enclosed area and prevent fire extinguishing fluids from exiting the enclosed area. Preferably, the elements comprises an elastically deformable material so that when the element is forced open, elastic energy is stored in the element to rapidly return the element to the closed state.

1. Arrangement for reducing harmful effects from fire and/or explosion, comprising means for enclosing an area which is exposed to fire and/or explosion, the means for enclosing the area comprising wall elements that are placed in adjacent relationship to one another to form a continuous wall, said elements being adapted, when a rapid pressure increase in the area in relation to the surroundings occurs, to open the area towards the surroundings until the pressure in the area is substantially balanced in relation to the surroundings, wherein the elements thereafter return to their closed state to enclose the area in relation to the surroundings, preventing air from the surroundings from entering the enclosed area and prevent fire extinguishing fluids from exiting the enclosed area, the elements comprise an elastically deformable material, and a number of parallel elongated dampers, which are pivotally suspended at upper, substantially horizontal edge. 2. The arrangement according to claim 1, wherein at least one element is adapted to store energy inflicted when the element is forced open, the energy is being used to rapidly return the element to the closed state. 3. The arrangement according to claim 1, wherein the area is provided with a fire fighting system. 4. The arrangement according to claim 1, wherein the pivot at the upper edge of the damper is a flexible hinge. 5. The arrangement according to claim 1, wherein at least one the element is mounted in a frame which is pivotable to open a portion of the wall for venting the enclosed area. 6. The arrangement according to claim 1, wherein at least one element is provided with a gasket along an edge thereof. 7. The arrangement according to claim 1, wherein at least one element is provided with magnets along an edge thereof. 8. The arrangement according to claim 1, wherein at least one element is provided with heat tracing cables. 9. The arrangement according to claim 1, wherein at least one element is provided with inflatable cavities. 10. The arrangement according to claim 1, further comprising a water fog nozzle with a first ejector, which is adapted to send out relatively large droplets, and a second ejector, which is adapted to send out relatively small droplets, wherein the ejectors are arranged beside each other in such a way that the relatively large droplets entrain the relatively small droplets. 11. The arrangement according to claim 10, wherein the ejectors are arranged in a venturi nozzle. 12. The arrangement according to claim 10, further comprising an ionization device at the ejectors, which is adapted to give the water droplets negative charge. 13. The arrangement according to claim 10, wherein the relatively large droplets have a diameter in the order of magnitude of 200-1000 μm and that the relatively small droplets have a diameter in the order of magnitude of 1-10 μm.
