The drawings with the mentioned constructions have to be submitted to the exhibition architect at least 4 weeks prior to the opening of the exhibition for review. If the design of the exhibition booth includes ceiling, the chief constructor of the Estonian Fairs shall make the decision about the primary fire extinction equipment and fire alarm system.

the second floor is at least at the distance of 2 meters from the border of neighbouring booth unless otherwise agreed in writing with neighbours
the allowed load on the floor and stairways of the second floor if applied as an office is at least 2,5 kN/m2 (250 kg/m2) and if open to the public 4,0 kN/m2 (400 kg/m2)
the height of vacant space of the lower floor of a 2-storeyed booth is 2,5 m max. and 2,2 m min.
evacuation distance of the second floor to the open staircase is 20 m max. and width of the staircase at least 120 cm. In case the area of the second floor exceeds 50 m2, there must be at least two steps
the height of the second floor and the boundary of paths leading there is appr. 1 m from a horizontal surface to the upper edge of the handrail. The part of the wall remaining under the handrail or correspondent construction must tolerate 0,4 kN/m (40 kg/m) linear load in a horizontal direction. The part consisting of the board of boundary must tolerate point load 0,3 kN (30 kg) in a horizontal direction. Should the boundary be subject to human weight, vertical point load 1,0 kN (10kg) must be considered
The fire extinction equipment of the lower floor of a 2-storeyed booth are as follows: manual extinguisher class AB-III-E 6 kg/l for lower and manual extinguisher AB-III-E 6 kg/l for the second floor per each 50 m2
