Fire of wooden multi-storey slab-systems in the city centers and experiences in the field of fire-fighting to avoid total devastation of buildings required engagement of fire section systems including fire doors. Basic structure of doors was made of wood overlaid by iron and the experts had to pay attention to deformation issued from heat.
