11B-405.8 Handrails.
Ramp runs shall have handrails complying with Section 11B-505.
[2010 ADAS] 405.8 Handrails. Ramp runs with a rise greater than 6 inches (150 mm) shall have handrails complying with 505.
Exceptions:
1. Reserved.
2. Reserved.
3. Curb ramps do not require handrails.
4. At door landings, handrails are not required on ramp runs less than 6 inches (152 mm) in rise or 72 inches (1829 mm) in length.
[2010 ADAS] EXCEPTION: Within employee work areas, handrails shall not be required where ramps that are part of common use circulation paths are designed to permit the installation of handrails complying with 505. Ramps not subject to the exception to 405.5 shall be designed to maintain a 36 inch (915 mm) minimum clear width when handrails are installed.
ETA Editor's Note
Since 2013 CBC lacks the Exception at employee work areas, and since it requires handrails at short ramps that are not curb ramps, 2013 CBC is more stringent regarding ramp handrails than 2010 ADAS.
