Steps should have a maximum riser of 0.15 metres and a minimum tread of 0.28 metres. Handrails should be provided to both sides of ramps and steps. Intermediate handrails are necessary where the ramp or steps are wider than 2 metres. Handrails should extend beyond the top and bottom of the steps or ramp and should be provided with a positive safe end.
