The Accessible Means of Egress Icon design is also consistent with the figures shown within international standards ISO 7001, ISO 7010, and ISO 21542.
It’s also consistent with the images presented in the booklet titled, ‘The international language of ISO graphical symbols’, which includes the ‘Running Man’ in safety green colour with a white pictorial element or icon.
The Accessible Means of Egress Icon design also includes a hatched line in a similar approach to the proposed new access symbol developed by Sara Hendren & Brian Glenney, as part of the Accessible Icon Project being used in many areas now to identify accessible car parking spaces and building entrances. Provision of the hatched line gives the image a sense of motion (and style), but more importantly allows the symbol to be used as a stencil for painting walls adjacent to exit doors.
