Stairs and staircases should be systematically cleaned of snow, ice, dirt and sprinkled with sand.

Not allowed:

1) people should be in the dangerous zone of working mechanisms, within the prism of a possible collapse on the ledges and in the immediate vicinity of the lower edge of the slope of the ledge.
