stair iconThe IBC contains requirements for exit stairway enclosures that address fire-resistance and smoke protection, stairways and handrails, signs, and other features. The ADA Standards apply requirements for stairways to each stair that is part of a required means of egress (§210). 

Exit Stairway Enclosures

Door leading to exit stairway enclosure with lighted exit sign above door and tactile exit sign adjacent to door.  Notes:  Exit Door Signs - The IBC requires illuminated exit signs at exits and exit access doors where two or means of egress are required (§1101 (2003), §1003.2.10 (2000)). In addition, tactile exit signs are required at exit doors leading to enclosed exit stairways and exit doors leading to outside. The ADA Standards apply requirements for tactile and visual characters to these signs (§216.4.1), which can be met on the same sign or separate signs. The IBC also requires signs on the interior of stairway enclosures indicating the floor level and other information.  Floor level designations, where provided, must meet tactile and visual criteria in the ADA Standards (§216.2), but directional and informational signs are subject only to provisions for visual characters (§216.3).  Door and Gates - The IBC covers doors and gates serving means of egress (§1008 (2003), §1003.3.1 (2000)). The ADA Standards permit fire doors to have the minimum opening force specified by the applicable life safety code instead of the 5 lbf maximum otherwise specified for interior hinged doors (§404.2.9).
