5.2.3 device should be level.

5.2.4 all channels, escalators, ladder or platform should be at least 0.5m wide channel, if the movable member and the fixed conveyor obstacles Channel width thereof is less than 0.5m, to be provided protection.

5.2.5 If the free space channel predetermined path moving conveyor and a fixed obstacle is less than 0.5m, to be provided protection.

5.2.6 above the floor 1.5m above the platform, floor or similar structure should be provided with a fixed channel. Which channel should be inclined with slats Slope or ladder, the angle with the horizontal ladder does not exceed 60 °. In the use of the ladder, ladder width between uprights should be a minimum of 0.35m; in the Free space port side, ladders and any obstacles between successive should be a minimum 0.6m; near the small width of the partial obstructions, since this The space can be reduced to 0.4m; on the other side, the free space between the ladder and any obstacles should be a minimum 0.2m.
