Ergonomics has made the following suggestions for the barrier free design of handrails: first, corridor handrails should be set at both ends of ramps, steps, stairs and aisles; second, the ends of handrails at the beginning and end of steps and ramps should be extended about 300 mm horizontally; third, the height of the first floor of handrails is about 800 ~ 850mm, and the height of two layers of handrails is about 850mm and 650mm; fourth, the height of handrails is about 850mm and 650mm The shape should be easy to grasp and firm, and the end of the handrail should be designed as a smooth curved surface, or directly extended into the wall; fifthly, the handrail which is concave inward into the wall can not occupy the traffic space, but also prevent accidental collision; sixth, in public spaces such as traffic buildings, medical buildings and government reception departments, barrier free handrails should be set at the starting and ending points Braille sign.

Armrest not only brings convenience to special groups and disabled people, but also plays an important role in the elderly. In the commercial shopping space, in addition to the ramps, steps, space scattered places, the necessary positions at both ends of the stairs need to be equipped with handrails, barrier free design also has outstanding requirements for the bearing capacity and easy grip of the handrails. Barrier free handrails should not only be strong and can bear 100kg of force, but also choose materials that are easy to grasp. Now, stainless steel and plastic are the most popular choices, mainly because they are easy to get and easy to handle. In the design of the handrail, the use of wood is added. If necessary, braille information should be embedded in the wood to facilitate the special groups and vulnerable groups to receive information.
The toilet for the disabled should be easy to find and approach, with barrier free signs as guidance. The ramp design of the population should be convenient for wheelchair access. The slope should not be greater than 1 / 12. The width of the ramp should be 120 cm. The net width of the entrance platform and door should not be less than 120 cm and 90 cm. There should be a wheelchair turning space with a diameter of not less than 150 cm. The toilet shall be equipped with sitting toilet, urinal, washbasin, barrier free armrest and other facilities for wheelchair users to enter and use conveniently.
