Article 14- Balustrade Dimensions and Safety requirements

Balustrade Dimensions

The vertical height from the step nose or pallet surface to the top handrail, on the slope, must be between 0.90 and 1.10 centimetres, as well suitable measures should be taken to prevent falling and discourage anyone from climbing the balustrade. Standing areas on the balustrade are not authorized.
Balustrades must withstand a simultaneously applied static lateral force of 600 N and vertical force of 730 N, both equally distributed over 1 m and acting on the top of the handrail guiding system in the same place.  

Balustrade Safety

Consider the following to ensure safety:
  • Balustrades parts on the side of the steps and pallets must be smooth and flush without sharp edges. Covers not placed in the direction of travel must not protrude more than 3 mm, and must be firm with rounded or beveled edges.
  • The joints in the direction of travel must not cause harm, injury due to trapping (Especially the joints between the skirt and the interior panels).
  • The gaps between the interior panels must be less than 4 mm with rounded or beveled edges(especially in glass panels).
  • If a force of 500 N is applied at any point at right angles to the interior panels surface in a (2500 mm2 square or rounded area), no gaps over 4 mm and no permanent deformations must be seen.
  • For the glass panels we must use tempered glass with a minimum thickness of 6 mm for single layered type. In case of multi-layered glass panels, we must use laminated tempered glass, which in this case at least one layer must be minimum 6 mm.
  • The inner lower decking is installed inclined and the angle of inclination created between the inner lower decking and horizontal must be at least 25 degrees. And this does not include the horizontal parts of the inner lower decking that joins the interior panels. This horizontal part must be less than 30 mm.
  • The horizontal width of each inclined inner lower decking at an angle of less than 45° must be less than 0.12 m.
