Navigation and Circulation: Vertical Circulation

Handrails

To ensure safety and accessibility, proper design and installation of handrails and guardrails are essential in stairways. Handrails should be easy to grip, positioned at two heights, and securely mounted to allow for smooth hand movement. They must be made of materials that are both durable and comfortable to use, with tactile indicators for those with visual impairments. Guardrails must be designed to prevent climbing and reduce risks, with appropriately sized gaps. Clear differentiation from surrounding surfaces and thoughtful placement contribute to a safer and more inclusive environment for all users.

Railing with height dimensions, vertical bars and handrails
  • Install handrails on all stairs that are easy to grip.
  • The handrails should have a circular diameter between 40 mm and 50 mm, and be 45 mm to 55 mm from the wall.
  • Ensure the handrail mounting system allows for continuous hand movement.
  • Place handrails on both sides of the stairs, extending 30 cm beyond the top and bottom.
  • Ensure handrails do not interfere with other circulation or usage areas.
  • Position handrails at two heights: one between 95 cm and 105 cm, and the other between 65 cm and 75 cm, measured from the edge of each step.
  • Choose handrail materials that are not too slippery or overly rough.
  • Avoid materials that can overheat when exposed to heat sources.
  • Consider adding tactile information, like Braille, on handrails for visually impaired individuals.
  • Differentiate handrails from surrounding surfaces with color contrast.
  • Ensure railings are designed to eliminate risks for users.
  • Gaps in guardrails should be no larger than 12 cm horizontally, and should be arranged to prevent climbing.
