Fittings on deck spaces to which passengers have access
(1) Every deck space to which any passenger has access shall be fitted with proper fittings to prevent persons falling therefrom.
(2) If such fittings consist of rails and stanchions-
(a) the top of the uppermost rail shall be not less than 3 feet 6 inches in height above the top of the deck; and
(b) in order to provide adequate protection for children, the rails shall be not more than 9 inches apart unless strong wire netting is placed between the rails.
(3) If bulwarks are fitted they shall be not less than 3 feet 6 inches high; and the freeing ports shall be fitted with suitable grids for the protection of children.
(4) The height of the rails shall be measured by the vertical distance from the top of the highest rail to the top of the deck at a point vertically below the inner edge of the rail:
Provided that where the deck has a waterway, the height of the rail shall be measured from the top of the highest rail to the top of the deck plank next to the waterway.
