The route away from a building should be an accessible path of travel at least 1,200 mm in width. Exit routes should be configured to ensure that everyone can quickly and safely clear the building. Routes should not require people to pass close to windows or traverse along the immediate perimeter of the building. Where exit routes require travel across landscaped areas, pedestrian paths should be of firm construction, with gradients complying with the requirements for accessible routes. These routes must be maintained clear of obstructions, such as snow and vegetation growth.
Exterior routes from the building should incorporate tactile and colour-contrasted walking surfaces for easier identification. Exterior emergency routes should be clearly identified on the life safety plan for the building and routinely practiced by all building occupants, especially those with blindness.
