28、ions indicated in the Figures 1 to 3 shall be complied with. The design of the equipment does not need to comply with the examples given. The cross section of parts designed to be gripped can be round, oval, a rounded rectangular or elliptical and shall be between 25 mm and 50 mm. BS EN 13451-2:2015

29、EN 13451-2:2015 (E) 6 4.1.2 Ladders NOTE Recessed ladders not protruding into the pool and asymmetric handle bends splaying to the pool surround and having a difference in height are preferred. If there is a distance between w1and w2,then it shall widen in an even transition on each side. The front

30、edge of all other treads shall be in the same vertical plane as the first tread with the plane having a tolerance of 10 mm from the top to the bottom of the ladder. The rise between each tread (h3) shall be equal. The upper tread shall be flush with the pool edge or comply with the dimensions given

If it is expected that the stepladder is used with a high frequency in both directions a greater width as given in 4.1.3.2 and 4.1.3.3 is recommended t

33、o make sure that two persons can pass (e.g. minimum 940 mm). If the width of the ladder exceeds 1 200 mm at least one additional handrail is required, which is at least 600 mm away from the other handrail(s). NOTE See Annex A for examples of easier access to the pool to address the needs of older pe

34、rsons and persons with disabilities. To prevent accidents caused by entrapment due to swimming underneath, the following applies: a) if the width of stepladder is 1 100 mm the closing of the open sides with an adequate device is mandatory; b) if the width of stepladder is 1 100 mm and access to the

35、area underneath the stepladder is possible, both sides shall be open and the stepladder shall be placed with min. 600 mm free space to each side. The distance between the top step and the wall shall be no more than 8 mm. BS EN 13451-2:2015EN 13451-2:2015 (E) 8 4.1.3.2 Fixed stepladders The handrails

36、 shall have a vertical height (h1) between 750 mm and 950 mm and shall lead back to the pool surround (see Figure 2). The ends of the handrails shall be bent downwards to a radius of at least 50 mm up to the horizontal line or in a curve of not less than 100. The handrails shall have the same inclin

37、ation as the stepladder itself. The maximum vertical distance (h2) between the top surfaces of two adjacent treads shall be 250 mm. The upper tread shall be flush with the edge of the pool border. The clear opening between two adjacent treads or the lowest step and the pool floor shall comply with t

38、he entrapment requirements according to EN 13451-1. The maximum angle of inclination with the horizontal shall be 45. The front edge of the upper step and the back edge of the lower step of two adjacent treads shall be on the same vertical plane or the treads shall be overlapping. Key d1 250 mm h175
