A vertical distance between the horizontal elements of guard-railing – no more than 0,5 m. A height of toe-board – no less than 0,15 m. There are also special requirements when using a mobile scaffolding. A slope of a surface on which the mobile scaffolding is being moved in transversal and longitudinal directions must not exceed the values, mentioned in the manufacturer’s manual for specific scaffolding structure.

Moving of mobile scaffolding is not allowed if the wind speed is more than 10 meters per second. Before moving the scaffolding it must be free of materials and material containers. No people allowed on moving scaffolding.

Each caster or wheel of mobile scaffolding must have a locking device. Access gates in the guard-railing of mobile scaffolding must open inwards and have a locking device that protects them from spontaneous opening.

There must be only those materials that are currently used. Works on the outside scaffolds have to be stopped in case of stormy weather with a speed of wind of more than 15 m/s, heavy snowfall, fog, icing of ground surface or other conditions hazardous to the health of workers.

During the disassembling of scaffolding constructed alongside the building, all the doorways of the first floor and balcony exits of every floor are closed within the area of disassembling. Scaffolding structures that have their decking at a height more than 1,3 m above the floor or the ground must be equipped with guard-rails. The height of guardrails must be no less than 1,1 m.
