Width of doors stairs and escape routes
- A door (or doorway) is the clear width when the door is open (see Diagram C1);
- An escape route is the width at 1,500 mm above floor level when defined by walls or, elsewhere, the minimum width of passage available between any fixed obstructions;
- A stair is the clear width between the walls or balustrades.
The rails used for guiding a stair-lift may be ignored when considering the width of a stair. However, it is important that the chair or carriage is able to be parked in a position that does not cause an obstruction to either the stair or landing.
