Application and safety requirements for handrails used with inclined ladders

1 Handrail2 Knee rail3 Kick plate4 Stanchions5 Walking surface

→ If the fall-height is greater than 500 mm a handrail must be installed.

→ A handrail is required if the distance between the platform and the machine or wall is greater than 200 mm or if the protection provided by the machine is not equivalent to that of a handrail. A kick plate is required if the distance between the platform and the support frame-work is greater than 30 mm.

Permanent Means of Access to Machinery – Stairs and Inclined Ladders

Use of handrails with stairs and inclined ladders Use of handrails with stairs

→ Stairs must have at least one handrail. Stairs with a useable stair width greater than or equal to 1200 mm must have two handrails.

→ If the total rise is more than 500 mm and there is an open space of more than 200 mm beside the string, a handrail must be mounted on this side of the stairs for protection.
