(4) The clearance on either side ofthe steps between the steps and the adjacent skirt guard shall not be more than 5 millimeters and the sum ofthe clearance on both sides shall not be more than 6 millimeters.
(5) A solid guard shall be provided in the intersecting angle ofthe outside balustrade (deck board) and the ceiling of soffit except where the intersection of the outside balustrade (deck board) and the ceiling of soffit are more than 60 centimeters from the centre line of the handrail.
