Dimensions of Landings (1) Except as permitted in Sentences (2) and (6), a landing shall be, (a) at least as wide as the width of the stair or ramp in which it occurs, and (b) at least as long as the width of the stair or ramp in which it occurs. [...] (3) Where a landing in a stair or ramp turns less than 90o, the length of the landing shall be measured perpendicular to the nosings of adjacent steps or to the end of the ramp, at a distance equal to half the length required by Sentence (2) from the narrow edge of the landing. [...] Guards (1) Every exit shall have a wall or a well-secured guard on each side where, (a) the difference in level is more than 600 mm between the walking surface and the adjacent surface, or (b) the adjacent surface within 1 200 mm of the walking surface has a slope of more than 1 in 2 away from the walking surface. [...] (3) The height of guards shall be measured vertically to the top of the guard from, (a) a line drawn through the outside edges of the tread nosings, or (b) the surface of the ramp or landing. [...] Loads on Guards and Handrails (4) The size of the opening between any two adjacent vertical elements within a guard shall not exceed the limits required by Part 3 when each of these elements is subjected to a specified live load of 0.1 kN applied in opposite directions in the in-plane direction of the guard so as to produce the most critical effect.
