Accessibility refers not only to the workplace, but also to the work equipment such as the hardware and software, doors and stairs, traffic routes, escape routes, emergency exits, orientation systems, lighting, washrooms and toilets or the furniture.
In general, accessible workplaces should meet the following requirements:
- controllability by the user
Depending on the needs of the groups of people, the so-called
- two-channel-principle (good accessibility and usability) respectively the
- two-senses-principle (good perceptibility and recognizability)
should be applied. For example, information can be displayed via visual-tactile or visual-acoustic sensory channels.
Legal and design requirements for barrier-free workplaces are laid down in the Workplace Ordinance (ArbStättV), in the technical rules for workplaces (ASR) and in various DIN standards and ordinances (e.g. DIN 18040 on barrier-free construction, DIN EN ISO 6285 on ergonomics, VDU workplace ordinance).
