ABSTRACT
Stairs represent one of the primary methods that we use for vertical circulation in a building, and are the heaviest used as means of escape. As stated earlier, the majority of disabled people will also be users of stairs, as they do not have a major mobility difficulty. In some buildings there is no alternative but to use stairs, as they are the only method for changing level. Because there will be a high percentage of disabled people using this medium, it is important to examine some of the features discussed below.
