have a minimum hand clearance of 50mm between the handrail and adjacent structure - there should not be any sharp edges or features that could cause injury during use.shaped for people to easily grasp their hand and fingers (like a 'power grip') around the handrail (circular or rectangular in shape).be between 900mm and 1100mm above the floor or the nosing of a stair tread.Stairways wider than 1000mm should have a handrail on each side. Each stairway should have at least one handrail.Handrails need to be easy to firmly grasp if a person loses balance. Handrails are a support aid when using stairs.Mark the rise and going of the step using a piece of paper If a difference is noticed, measure the rises and goings with a ruler.ġ. Compare the markings to see if there is a difference in step dimensions.Mark the step rises starting from the bottom step on a sheet of A4 paper.Marking and checking indicates if steps are inconsistent in dimensions. Fix irregular steps and highlight irregular steps with different pattered or coloured slip resistant nosing.Fix short steps and highlight short steps with different patterned or coloured slip resistant nosing.Īn irregular step is longer or shorter than the other steps in a flight of stairs.Check to see if the ball of the foot fits on the step when walking on them.Highlight the isolated step with a handrail.Ī short step does not provide adequate support for the ball of the foot to safely walk down stairs without slipping.Highlight isolated steps with nosing that is slip-resistant and in a different pattern/colour to the tread.Remove any unnecessary level changes and single steps where possible.Isolated stepĪn isolated or surprise step is a single step that is not clearly visible or expected. Isolated, short steps and irregular or inadequate stair dimensions can cause falls. A standing space of at least 600 mm that is clear from cross-traffic and a door swing or any other structure must be provided.ġ Based on Australian Standards 1657 (2018) Fixed platforms, walkways, stairways and ladders – Design, construction and installation Common hazards when using stairs 1.Stairway landings should not be less than the width of the stairway.Adjacent flights should be connected by a landing.A single flight should have a minimum of two risers and maximum of 18 risers.It is recommended the angle be between 30 and 38 degrees. The angle of stairways should be between 20 and 45 degrees to the horizontal tread. ![]() Nosing/edge of step should be slip resistant, in good condition and clearly visible against the background (in all lighting conditions).A tread surface should be slip resistant.A tread should extend across the full width of the stairway.Design requirements for stairs and steps 1Īll risers and goings on the same flight of stairs should have uniform dimensions within a tolerance of ±5 mm. Use this information to reduce falls on stairs and steps at your workplace.Īs risk management guidance, this is not intended to replace the need to refer to relevant building codes and standards depending on your particular circumstances.
