CODE OF PRACTICE FOR METAL SCAFFOLDING SAFETY
(iv) Gangways and working platforms should preferably be horizontal but
may slope at an inclination of up to 1 vertical to 4 horizontal without
stepping laths. At slopes steeper than this they should be provided
with stepping laths to provide a firm foothold.
(v) Ladders or other suitable means should be provided so as to
enable workers to gain access to and egress from one platform to
another.
(e) Stair/ladder access to and in scaffolds
Stair and ladder towers should be constructed with one side common with
the outside of the scaffold. Bracings should be fixed to the remaining
sides except in the bays through which access and egress is required.
The superimposed loading adopted in calculations should be not less than
2kN/m 2 for all landings and stairs in stair towers and ladder towers.
(i) Every sloping ladder should stand on a firm and level base and be
supported only by the stiles. The stiles should be securely fixed to the
scaffold by lashings or by other attachments at the top.
(ii) Ladder should be set at an angle of 4 vertical to 1 horizontal.
(iii) Ladders should project at least 1.05m above the top landing with the
landing rung level with or slightly above the level of the landing.
Ladders should not be extended by lashing two lengths together.
(iv) The vertical distance between two successive landings should not
exceed 9m. The landings should be provided with access holes for
the user which should not exceed 500mm in width and should be as
small as practicable in the other direction.
(v) Where practicable, the ladder access to the scaffold should be with
its own ladder tower fixed to the outside of the main scaffold.
(vi) Both ladder towers and stair towers should be fully decked at the
landings. Toe-boards should be provided at the landings.
