In this installment of our blog series, we continue to focus on more details that changed with the new OSHA regulations – specifically design changes that affect stairs.
OSHA 1910.29 says that for any stairs installed after January 17, 2017, a handrail that measures 30-38 inches is required, as well as a 42-inch stair rail. The rationale for this additional requirement is that the handrail is provided to guide an individual up or down the stair, while the stair rail—effectively guardrail—is provided for fall protection.
In addition, some of the other changes for stair design include:
Item
Old Rule
New Rule
Overhead clearance
84 inches
80 inches
Handrail height
30-34 inches
30-38 inches
Guardrail
N/A
42 inches
It’s important to make note of these new rules related to stair design so that they can be incorporated into any new stairs that are being added to your facilities. See Figures D-12 and D-13 referenced in OSHA 1910.29 (f) for more information and visual diagrams of the requirements.
According to OSHA 1910.29 (f)(1)(ii)(A), retrofit of existing stairs is not required, as long as the height of stair rail systems is not less than 30 inches from the leading edge of the stair tread to the top surface of the top rail.
To understand the rationale or research related to these changes, you can find information in the commentary. Trust me when I say they went into a lot of detail.
