What you should know about OSHA’s proposed revision to the stair rail system requirements
Who knew stairs could be this complicated? OSHA has proposed changes to the Walking-Working Surfaces standards to clarify certain requirements related to handrail and stair rail systems. Familiarity of the current standard and proposed changes will keep employers from being caught off guard should the standards change.
Stakeholders have expressed confusion when handrails are required on stair rail systems, as well as their height requirements, depending on date of installation. This misunderstanding is driving the proposed rule change. Before an employer starts second-guessing the status of their handrails and stair rail systems, it’s a good idea to break down the current regulation into bite-sized parts to better understand exactly what is happening.
What is a stair rail, stair rail system, and handrail?
According to 29 CFR 1910.21, a stair rail (also known as a stair rail system) is a barrier erected along the open side of a stairway to prevent employees from falling to a lower level. A handrail, also defined in 1910.21, is a rail used to provide employees with a handhold for support.

Current rule – stair rail system
Each flight of stairs having at least 3 treads (i.e., horizontal member of a stairway) and at least 4 risers (i.e., vertical member of a stairway) must be equipped with a stair rail system and handrails, as specified in Table D-2 of 1910.28(b)(11)(ii). These Stairway Handrail Requirements are based on stair width and how many sides of the stairway are open or exposed.
Current rule – handrails
According to 1910.29(f)(1)(iii)(A), OSHA allows the top rail of a stair rail system to serve as a handrail when certain conditions are met, including but not limited to:
- the height of that stair rail system is not less than 36 inches and not more than 38 inches; and
- the stair rail system was installed before the effective date of the rule (January 17, 2017).
Proposed changes – stair rail system
An amendment to Table D-2 would correct a formatting error in a cell that currently reads “One stair rail system each open side,” to state “One stair rail system with handrail on each open side.” This seemingly small change would mean that, on new stair rail systems, any open side would need handrails. OSHA understands that this change could mean employers would need to update current stair rail systems, so they are proposing provisions for stair rail systems that were installed before the effective date of the new final rule, should modifications be needed.
Proposed changes – handrails
To alleviate confusion on when the top rail of a stair rail system may also serve as a handrail (i.e., combination top rails/handrails), in May of 2021, OSHA proposed to expand the height range in proposed paragraph (f)(1)(ii)(A). This would mean that the top rail of stair rail systems installed prior to the effective date of a new final rule can serve as a handrail if that top rail is 30 to 38 inches in height and meets the other handrail requirements. After accepting and reviewing comments, OSHA announced that it will re-open the rulemaking in late 2023, possibly revising the previously proposed changes.
It is unknown if or when these changes will move to the later stages of OSHA’s rulemaking process but it’s something to keep an eye on as it has the potential to affect numerous businesses.
Remember that OSHA’s intent with these particular proposed changes is to reorganize the Walking-Working Surfaces rule in order to clarify which handrail and stair rail system requirements apply to new stair rail systems. These changes are expected to maintain the same level of safety and health protections for workers compared to the current (2016) standard, not add to the employer burden.
Key to remember: Businesses with stair rail and handrail systems should be aware of OSHA’s proposed rulemaking to the Walking-Working Standards and proactively assess if they may be impacted.
