OSHA's Table D-2 Typo: What the 2026 Interim Guidance Means for Stair Rails Under 44 Inches

If you have walked an industrial mezzanine in the last 10 years, you have probably walked past the OSHA typo at the center of this article. Table D-2 of 29 CFR 1910.28(b)(11)(ii) — the table that tells facility owners how to fall-protect a stairway — was finalized in 2016 with five words missing from the row for narrow open stairways. The result was a decade of EHS managers reading the literal table and an OSHA-intended requirement that nobody could see in the rule.

On February 26, 2026, OSHA issued interim enforcement guidance to finally resolve the contradiction. The guidance does not retrofit your existing stairways. It does change what your next mezzanine install looks like, and it gives you a defensible position for the systems you already own — provided you can document them.

⚡ TL;DR: Table D-2 should have read “One stair rail system with handrail on each open side” for stairways less than 44 inches wide with two open sides. It accidentally shipped without the “with handrail” language. OSHA’s 2026 interim enforcement guidance lets you install to the corrected language now without citation risk under 1910.28(b)(11)(ii) or 1910.29(f)(1). Existing stair-rail-only installations that complied at the time of install are grandfathered — if you can document the date and the specs. Fall protection has been OSHA’s #1 most-cited violation for 15 straight years. Per-violation penalty cap: $16,550 serious / $165,514 willful (2025).

What the Table Was Supposed to Say

The fall protection requirements for general-industry stairways live in 1910.28(b)(11)(ii) and the supporting criteria in 1910.29(f). Table D-2 lists what fall-protection systems each combination of stairway width and open-side count requires.

The row in dispute covers stairways with two open sides and a width less than 44 inches. As published, the row reads:

“One stair rail system each open side.”

OSHA’s 2021 NPRM (86 FR 27429, Federal Register May 20, 2021) acknowledged the wording was a formatting error and that the row was intended to read:

“One stair rail system with handrail on each open side.”

The proposed correction tracks language OSHA published in its 2010 proposed rule and intended to carry into the 2016 final rule. The 2021 NPRM proposed two things: correct the table for new installations, and grandfather existing stair-rail-only systems that complied with the literal table when installed.

The final rule has not yet been published. The interim enforcement guidance is the bridge.

What the 2026 Interim Guidance Actually Does

The February 26, 2026 Interim Enforcement Guidance for Handrail and Stair Rail System Requirements is short and operational. The key directive: OSHA will not issue citations under §§ 1910.28(b)(11)(ii) or 1910.29(f)(1) where the installation complies with the proposed requirements in the 2021 NPRM. Two practical consequences follow.

For new installations. Install to the corrected language — a stair rail system on each open side and a handrail. The guidance specifies that the stair rail top rail must be at least 30 inches above the leading edge of the tread for new systems, and that where the top rail of the stair rail system falls within the 30–38 inch handrail height window, it can also serve as the handrail. That combination provision (covered in the same interim guidance) means a single piece of steel can satisfy both standards if specified correctly.

For existing installations. Stair-rail-only systems installed before any future final rule’s effective date stand, provided they complied with the literal text of 1910.28(b)(11)(ii) and 1910.29(f) at the time of install. The guidance preserves the position the 2021 NPRM proposed.

The Documentation Problem Nobody Is Talking About

The grandfather position only works if you can prove the install date and the specifications. The interim guidance does not create a presumption in your favor; it tells the compliance officer not to cite where the conditions are met. If the installation date is unknown and the specifications are not documented, the compliance officer is not obligated to assume in your favor.

The practical action item for facility owners with multiple mezzanines, equipment platforms, and catwalks is a documentation walk: stairway-by-stairway, capture the install date (or best-estimate range from facility records, drawings, or asset registers), the top-rail height, the handrail height (if installed), the grip dimensions, and the clearance from any obstruction. Build the file before the inspector pulls the question.

This is the kind of work iSi handles routinely as part of fall-protection program updates — the program lives in 1910.30, and a written program without a defensible inventory of in-place systems is not actually a program.

What to Install on Your Next Mezzanine

For new construction or stairway replacements at facilities with narrow open stairways, comply with the corrected language now. The full criteria for handrails and stair rail systems live in 1910.29(f):

Stair rail system on each open side. Top rail at least 30 inches above the leading edge of the tread for new systems (the existing 1910.29(f)(1) minimum for stair rail systems installed before 2017 is 36 inches; new systems install to the proposed-rule criterion in the interim guidance).
Handrail on each open side. Handrail height 30–38 inches from the leading edge of the tread. Circular grip 1¼–2 inches diameter, or non-circular sized to provide equivalent gripping surface. Clearance from any other surface at least 2¼ inches. Continuous gripping surface the full length of the stairway.
Combination rail/handrail option. Where the top rail of a stair rail system is within 30–38 inches and meets all handrail criteria (grip dimensions, clearance, gripping surface), it can also serve as the handrail. This is the most cost-efficient install for narrow open stairways — one fabrication, two standards satisfied.
Stairways 44 inches wide or wider. Requirements are unchanged. Both stair rail systems and handrails apply per Table D-2 as written.

The Penalty Math: Why This Matters at Inspection

Fall protection has been OSHA’s #1 most-cited violation for 15 consecutive years. FY2025 produced 5,914 fall protection citations across all jurisdictions. While construction (1926.501) drives most of that volume, 1910.28 is a steady contributor in general industry — and stair, ladder, and elevated-platform issues are perennial during programmed inspections and after fatal falls.

Per-violation cost under the 2025 civil penalty adjustments:

Serious violation: $16,550 maximum
Willful violation: $165,514 maximum, $11,524 minimum
Failure to abate: $16,550 per day

The exposure for Table D-2 ambiguity rarely runs willful — the entire point of the interim guidance is that good-faith reliance on the literal table is not a willful problem. The real risk is stacking across multiple stairways. A multi-mezzanine plant where six stairways are flagged in one inspection can see proposed penalties stack into the $50,000–$100,000 range at the serious tier. The cure — handrails or combination rails installed to the corrected language — is a small fraction of that exposure on a per-stairway basis.

State-Level Notes for iSi’s Service Region

In Kansas, Oklahoma, Missouri, Nebraska, Arkansas, and Texas, federal OSHA enforces 1910.28 directly. The February 2026 interim guidance applies as written. Kentucky’s state OSH plan (KY OSH) adopts the federal Subpart D requirements; interim guidance typically tracks federal enforcement memoranda but practitioners should confirm KY OSH’s adoption posture before relying on it directly.

Three Actions to Take This Quarter

Walk your stairways. Catalog every stairway in scope: width, number of open sides, install date if known, top-rail height, handrail presence and height. The output is a one-row-per-stairway inventory that supports the grandfather position for legacy installations.
Apply the corrected language to all new and replacement installs. Specify combination rail/handrail where the 30–38 inch window allows it. Engineer the install once; satisfy both standards.
Update your written 1910.30 fall protection program. Reference the February 26, 2026 interim guidance, the corrected Table D-2 language for new installations, and the documented status of legacy systems. A written program that doesn’t address known regulatory ambiguity gets cited even when the physical installation is fine.

If your facility has multiple mezzanines, equipment platforms, or process catwalks — and especially if records on install dates and specifications are thin — that’s the work iSi can plug into. We do the walk, write the inventory, update the fall protection program, and leave you with a documented position the compliance officer can read at inspection. Reach out and we will scope the site.
