1910.28(b)(11) – requires employers to protect workers from falling off stairway landings and exposed sides of stairways.

  1. Unprotected sides or edges of a stairway landing four feet or more above a lower level, must be protected by a guardrail or stair rail system.  Flights of stairs having at least three treads and four risers, must also be equipped with railing and handrails.

When floor space is limited, requiring the use of the much steeper ship stairs or alternating tread-type stairs (50 to 70 degrees from the horizontal), OSHA also requires these be equipped with handrails on both sides.
