Accessibility refers not only to the workplace, but also to work equipment such as hardware and software, doors and stairs, traffic routes, escape routes, emergency exits, orientation systems, lighting, washrooms and toilets or furniture.
In general, barrier-free 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) or the
- Two-sense principle (good perceptibility and recognizability)
to use. For example, information can be displayed via visual-tactile or visual-acoustic sensory pathways.
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 for barrier-free building, DIN EN ISO 6285 for ergonomics, VDU workplace ordinance).
