PLAYGROUND EQUIPMENT WITHOUT BARRIERS. The requirements of DIN33942 have been specified to allow a large extent for all people to use the equipment without the help of others. This applies particularly to wheelchair users (also with upper body disability) and to the blind, deaf people with visual, hearing, motor or other impairments. The following parameters are only a guide to take into account when if supervising a playground equipment without barriers:
•
The ramps should not have an inclination of more than 6%
•
The spaces and openings between floor boards must not be larger than 8 mm.
•
Wheel deflectors must have a minimum height of 100mm. If possible these guardrails should have a contrast colour to facilitate orientation of those who have a visual impairment.
•
Two wheelchairs located across the width require a minimum floor space of 1,8m so they can rotate.
•
The zones of displacement destined to changes of direction or stops, entrances and exits of the elements, should have a 1,5x1,5m. The other movement surfaces must have a minimum width of 1,2m.
In addition to these generalities, it is important to bear in mind that a playground without barriers implies much more that the fact the elements meet certain dimensions; the entire environment must contain signs or elements that indicate those areas that may be dangerous. At least two of these signals must refer to some sense (sound, tactile or visual elements are usually used) so that any child is able to detect where they should be most attentive, regardless of their abilities. And of course, we all must be aware of the need for this type of spaces to try to get it normalized.
