Handrails should be provided on both sides of a ramp or stairs in order to support people with reduced mobility and guide people with visual difficulties.
There should be two rails, one at a height of 90 cm and another at 70 cm (for children and people of short stature).
The shape of handrails should be cylindrical in order to facilitate the grasp (diameter between 40 and 50 mm).
For security, handrails must also be installed with a ramp higher than 40 cm to avoid the falling risk and they shall be solid enough to support body weight.
