Material & ColourHandrails should be smooth throughout the length without any sharp edges and preferably round or oval in cross-section. They should be a in contrast to the background colours by at least 30%.
Extensions (Fig. 8):The extension of the handrails should be 300mm at both ends beyond the first step and last step.
Handrail Placement (Fig. 4 & B, D):The handrails should be on both side of the steps and if the steps are more than 3000mm wide then there should be more handrails at an interval of not greater than 2000mm. If a handrail is attached to a wall there should be a clearance gap of a minimum of 50mm.
Handrails on Building Plinths (Fig. 2 & D):All buildings having stepped level changes around them, such as raised plinths, must have handrails next to the entrances, ATMs, and other features like seating areas etc.
External Stairs:Should be well-lit and covered against weather.
Tactile Ground Surface Indicators TGSI (Fig. 3 & 4):These are a tactile provision for the visually impaired that they feel through their feet. They are provided to help guide them to entrances, lifts, steps, ATMs and road crossing etc.
“Warning”, dotted TGSI tiles, should be at distance of 300mm from features like level changes, at the top and bottom of steps, entrances, lift controls, etc
Types of Stairs not allowed in public buildings:
Open Step (Fig. C):Are dangerous and not allowed. Then can cause mis-placing of foot/or walking step.
Turning Step - “Kite” and spiral. (Fig. F & G).These are not allowed as any other type of uneven depth step.
