OSHA 1926.1052(c)(1): handrails and stair rails on construction stairways
Under 29 CFR 1926.1052(c)(1), a construction stairway with four or more risers, or rising more than 30 inches, whichever is less, must have at least one handrail and a stairrail system along each unprotected side or edge.
Official text
(c)(1) Stairways having four or more risers or rising more than 30 inches (76 cm), whichever is less, shall be equipped with: (i) At least one handrail; and (ii) One stairrail system along each unprotected side or edge. Note: When the top edge of a stairrail system also serves as a handrail, paragraph (c)(7) of this section applies.Read the full section on eCFR
(c)(3) The height of stairrails shall be as follows: (i) Stairrails installed after March 15, 1991, shall be not less than 36 inches (91.5 cm) from the upper surface of the stairrail system to the surface of the tread, in line with the face of the riser at the forward edge of the tread. (ii) Stairrails installed before March 15, 1991, shall be not less than 30 inches (76 cm) nor more than 34 inches (86 cm) from the upper surface of the stairrail system to the surface of the tread, in line with the face of the riser at the forward edge of the tread.Read the full section on eCFR
(c)(6) The height of handrails shall be not more than 37 inches (94 cm) nor less than 30 inches (76 cm) from the upper surface of the handrail to the surface of the tread, in line with the face of the riser at the forward edge of the tread.Read the full section on eCFR
What it requires, in plain English
- The trigger is four or more risers or a rise of more than 30 inches (76 cm), whichever is less.
- Each such stairway gets at least one handrail, plus a stairrail system on every unprotected side or edge.
- Stairrails installed after March 15, 1991, are at least 36 inches from the top of the rail to the tread surface, measured in line with the face of the riser.
- Handrails are between 30 and 37 inches above the tread, measured the same way.
Where it shows up on site
- Temporary wood stairs to a trailer or mezzanine with open sides
- Pan stairs in a stair tower before permanent rails are set
- A rail pulled off to move material and not reinstalled
Verify on site before you call it
A photo rarely shows every fact a standard depends on. Confirm these in person before treating the condition as a violation:
- How many risers does the stairway have, and how high does it rise in total?
- Which sides are unprotected, and is a wall or other structure enclosing any side?
- When was the stairrail installed, and what is its height measured at the riser face?
- Does the top rail also serve as the handrail, which brings in the height range of 1926.1052(c)(7)?
Typical corrective actions
- Close the stairway or restrict use until a handrail and stairrails are in place on unprotected sides.
- Install a stairrail system on each unprotected side or edge and at least one handrail.
- Measure rail and handrail heights at the riser face and adjust them to the required range.
- Add the missing midrail, screen or other intermediate member between the top rail and the steps.
Common questions
How many steps before OSHA requires a handrail on a construction stairway?
Under 1926.1052(c)(1), a handrail and stairrails are required when a stairway has four or more risers or rises more than 30 inches, whichever is less. A short stair that rises more than 30 inches needs them even with fewer than four risers.
What is the difference between a stairrail and a handrail?
A stairrail system runs along an unprotected side or edge to keep workers from falling off the stair; stairrails installed after March 15, 1991, are at least 36 inches high. A handrail is what workers grasp, set between 30 and 37 inches above the tread. A stairway needs at least one handrail even where both sides are enclosed.
Turn the observation into a notice
Record what the photo shows, confirm the on-site checks above, and identify the responsible company and due date. Use the fillable construction safety notice template or follow aworked example from observation to verified fix. Cirqify can draft the notice from your circled photo for you to review.
