1910.23 vs 1910.28 — Who Does What

Compliance officers cite one section for design and a different one for protection duty. This table splits the responsibilities the way an inspector reads them — geometry from 1910.23, obligations from 1910.28, vocabulary from 1910.21.

Section	Its job	Numbers you cite	Fails when
1910.21	Definitions — fixes what a fixed ladder, LSS and fall arrest system are	Named terms used by both sections below	Equipment is classified into the wrong category
1910.23	Design and construction of the ladder itself	Rung clear width at least 16 in; rung spacing; load carrying; cage geometry where a cage is used	Rungs, spacing or cage dimensions measure outside tolerance
1910.28	Duty to provide fall protection on the climb	24 ft trigger; cage vs ladder safety system vs personal fall arrest; Nov 19, 2018 and Nov 18, 2036 dates	A new over-24 ft ladder ships with a cage but no system

In practice: our fabrication drawings answer to 1910.23, and your scenario — height plus installation date — answers to 1910.28. The free assessment checks both columns before quoting, so neither side of the audit has a gap.

Enforcement Perspective

Citation Map — Every Number an Officer Carries Into a 1910 Inspection

A walking-working-surfaces inspection is three sections deep: 1910.21 fixes the vocabulary, 1910.23 fixes the steel, 1910.28 fixes the duty. Officers carry the numbers below in their heads. Your file should carry them too — each mapped to the as-built figure we deliver.

Clause Home	Number on the Tape	Our As-Built Figure
1910.21 — definitions	fixes cage, LSS and PFAS so the right rule attaches to your equipment	DoC names the correct equipment class
1910.23 — rung clear width	≥16 in between side rails	500 mm — 19.7 in
1910.23 — cage inside width	27–30 in from climbing centerline	Φ700 mm — mid-band
1910.23 — hoop spacing	≤6 ft 6 in vertical between hoops	1500 mm — 4 ft 11 in
1910.23 — flare and start	bottom flare ≥4 in; cage starts 7 ft 6 in–8 ft above base	flared band, 2.29–2.44 m start on OSHA builds (2.2 m factory start reserved for EN builds)
1910.28 — duty threshold	fall protection required above 24 ft	climb height marked on drawing; LSS route quoted
1910.28 — transition dates	new installs since 2018-11-19 need LSS or PFAS; cages grandfathered to 2036-11-18	entitlement dates documented per shipment

The trap sits in the last two rows: a ladder can pass every 1910.23 number and still cite under 1910.28. Geometry and duty are separate findings — which is why our dimension sheet and our entitlement dates print on the same page.

Compliance Decision Guide

Geometry Pass, Duty Fail — Escaping the Two-Section Trap

The most expensive cage ladder mistake in the United States is buying perfect 1910.23 steel for a climb where 1910.28 wanted a system. Five scenarios straddle the two sections — here is how each resolves, and what we ship for each.

Scenario	How It Resolves	Our Supply
20 ft climb, new build	1910.23 governs fully; 1910.28 never triggers — a cage is the complete answer	caged ladder to full 1910.23 geometry, HDG from $95/m
26 ft climb, new build	1910.23 geometry still applies, but 1910.28 demands LSS or PFAS since 2018-11-19	LSS-ready ladder; cage optional as added restraint below duty
26 ft climb, cage present since 2015	entitlement holds to 2036-11-18 — maintain, document, monitor rulemaking	repair sections to original geometry, dated file updates
Climb measured at 23 ft 10 in	borderline heights get measured from the access level — resolve the number before choosing	free height determination from your photos within 24 h
Inspector cites 1910.23 width on an old cage	geometry findings stand regardless of grandfathering — repair the dimension, keep the regime	hoop and strap rebuilds inside the 27–30 in band

Both sections print on one dimension sheet from us — geometry on the left, duty determination on the right — so no order leaves the factory answering only half the law.

What Clause-Level Building Buys You

From Sub-Section to Signed-Off Steel

Five deliverables that map our fabrication directly onto the sections inspectors cite.

Feature	Advantage	Your Outcome
1910.23 numbers printed per order	each dimension tied to its clause on one sheet	geometry findings have nothing left to measure
Duty determination on the same page	1910.28 answered where the geometry lives	the two-section trap closes at purchase
Definitions-accurate DoC	equipment class named per 1910.21 vocabulary	no clause-shopping against your file
Borderline-height determination, free	23 ft 10 in resolved before you buy	the 24 ft line never surprises you
Entitlement dates shipped with the steel	install dates documented at manufacture	2036 questions answered by records, not recall

Osha 1910.28 Cage Ladder FAQ

What is the difference between OSHA 1910.23 and 1910.28 for cage ladders?

OSHA 1910.23 covers the physical requirements of fixed ladders — clearances, rung spacing and dimensions. OSHA 1910.28 covers the fall protection duty, including the 24 ft threshold and the 2036 end of cage grandfathering on existing ladders.

What is the 24 ft threshold in 1910.28?

Above 24 ft, fall protection becomes mandatory. For ladders that carried a cage before 2018-11-19, the cage satisfies that duty until 2036-11-18. For ladders first placed in service after 2018-11-19, the protection must be a ladder safety system or personal fall arrest — the threshold arrived with the 2018 rule, not in 2036.

What is the 2036 phase-out date?

November 18, 2036 is when existing cages on over-24ft ladders lose their grandfathered status — after that date the protection must be a ladder safety system or personal fall arrest. Honest status note: OSHA proposed removing that deadline in September 2025, not final as of August 2026 — so plan to the date that is on the books.

Which 1910.23 findings can we self-clear before the inspector measures?

All the geometric ones: rung clear width against 16 in, cage width against the 27–30 in band, hoop spacing against 6 ft 6 in, flare against 4 in, cage start against the 7 ft 6 in–8 ft window. The free checklist maps each figure to its clause — measure with it quarterly, and the tape holds no surprises. What it cannot self-clear is the duty side: entitlement dates under 1910.28 need records, which our shipping papers provide.

Which section gives cage dimensions and which gives the fall protection duty?

1910.23 is the geometry section — rung clear width of at least 16 in, rung spacing and load carrying. 1910.28 is the duty section — it decides at 24 ft whether a cage still qualifies or a ladder safety system and personal fall arrest are required.

What does OSHA 1910.21 actually do?

1910.21 is the definitions section. It fixes the meaning of terms like fixed ladder, ladder safety system and personal fall arrest, so that 1910.23 and 1910.28 read consistently across every inspection and citation.

Does 1910.23 apply even when my ladder is under 24 ft?

Yes. The design and construction requirements apply to fixed ladders regardless of height — a 15 ft ladder still needs compliant rungs and spacing. The 24 ft line in 1910.28 only decides when fall protection becomes mandatory on a climb.

Can a ladder meet 1910.23 geometry but still fail under 1910.28?

Yes — and it is the most common gap we see. A brand-new ladder with a perfectly dimensioned cage fails compliance if the climb exceeds 24 ft, because after November 19, 2018 a cage alone no longer counts as fall protection on new installations.
