The pitch of the staircase must not exceed 60º to the horizontal surface. If the scaffolding is installed close to the driveways then the gap between the scaffolding and the vehicles should be more than 0,6 m. The height of the scaffolding is measured from the ground level, floor or platform on which it is installed. Decks and staircases have to be cleaned periodically during the works and after their completion. In the winter time, the snow and ice are needed to be removed and the sanding to be done.

Under each pair of base plates in transversal direction should be put a wooden plank of one piece with thickness over 5 mm. It is put on the compacted and even ground surface. To make the plank lay even by using the fragments of broken planks or other scrap is not allowed. When constructing the scaffolding of more than 6m in height there should be more than two levels of decking: working (top) and guard (bottom) and each working place on the scaffolding adjoined to the building facade should be protected from above by one more decking.

To perform the works on several levels simultaneously along the same vertical line without intermediate guard decking between the levels is not allowed. The distance between the staircases, used for convenient access to the scaffolding, must be less than 40 m. If the whole scaffolding structure is less than 40 m in length then it must be equipped with two staircases at the least.
