A large-scale container, preferably transportable and closable by a fireproof sliding door composed of several leaves, includes a fireproof bulkhead which is mounted parallel to the leaves along the ceiling of the large-scale container. The bulkhead extends over the entire width of the sliding door and projects in a gap defined by the spaced arrangement of the leaves, with the bulkhead and the leaves being provided along their facing sides in the overlapping areas with a fireproof intumescent coating. In this manner, a direct penetration of flames in this area into the interior is prevented and the space defined between the leaves and the bulkhead is closed by a fireproof intumescent coating to attain a hermetic seal.
