Technical Booklet H Stairs Ramps Guarding and Protection from Impact·Page 38·4.16
Width of ramps
Ramps and their landings must have a minimum surface width of 1500 mm. Handrails may protrude up to 110 mm into this width. Ramps wider than 1800 mm must be divided into separate ramps, each meeting the 1500 mm minimum width.
A ramp or ramps and landings should have a surface width of not less than 1500 mm. Where a handrail protrudes into the surface width of a ramp by more than 100 mm the surface width should be increased accordingly. In any case the maximum protrusion of a handrail into the surface width of a ramp should be 110 mm. A ramp which has a surface width greater than 1800 mm, it should be divided into ramps which are not greater than 1800 mm. The minimum surface width of 1500 mm will then apply to each ramp.
