B-24.2.16 Graphical Symbols

The international symbol of accessibility (see Fig. 105)

shall be replicated consistently in all wheelchair signage. The preferred colour is navy blue with white lettering.

105A PROPORTIONS

Graphical symbols should be used in conjunction with building signage system, wherever possible.

Graphical symbols shall be highly contrasted with a minimum difference in LRV of 70 points and properly illuminated. They shall be used on guides and directional signage (see also B-24.3).

Graphical symbols on directional and door signs should be tactile, and should be accompanied by raised lettering and Braille (see B-24.2.13). Signs above a height of 1 600 mm do not need to be tactile, nor to include raised lettering or Braille information.

The size of graphical symbols is dependent on the viewing distance $(D)$. The minimum size of the inner outline of the frame of graphical symbols (s) can be derived from formula $s = 0.09$ $D$, applicable for a viewing distance of $1000\mathrm{mm}$ to $10000\mathrm{mm}$.

The following accessible graphical symbols shall be used to denote particular components of a facility. The following facilities for disabled persons shall be marked as:

a) Those relating to people with mobility impairments,

1. car parking places (parking places, garages);

2. access and entrances without steps to buildings, especially where they are not identical with the main entrance;

3. accessible lifts, in cases where not all lifts are accessible; lifting platforms and similar mounting devices;
