Corridors and passageways with gradients
Corridors steeper than 1 in 60 but less steep than 1 in 20 must have horizontal rest areas and limited rise between them. Gradients must be distinguishable and guarded where there is a risk of falling.
Where a corridor or passageway has a gradient –
(a) that is steeper than 1 in 60 but less steep than 1 in 20, it should have –
(i) horizontal rest areas not less than 1500 mm long; and
(ii) a rise of not more than 500 mm between rest areas;
(b) the gradient should extend the full width of the corridor or passageway or –
(i) have any exposed edge of the gradient distinguishable, through suitable visual contrast; and
(ii) be adequately guarded where there is a risk of falling.
