While the IBC defines the ‘accessible means of egress’ as a “continuous and unobstructed way of egress travel from any accessible point in a building or facility to a public way.”[1], the 2010 ADA Standards enhances this definition to include reference to an area of refuge or horizontal exit also; “a continuous and unobstructed way of egress travel from any point in a building or facility that provides an accessible route to an area of refuge, a horizontal exit, or a public way”.

Accessible signage and directional signage in line with IBC Section 1007 is also required in the ADA Standards (Section 216 and 703). Though, in a similar approach to IBC 2009 and IBC 2012, there is no requirement in the ADA Standards to provide the International Symbol of Accessibility on signs for components of the accessible means of egress.
