Fixed Ladder Cage Requirements Under OSHA 1910.28: The 2036 Deadline

Under OSHA 1910.28(b)(9), fixed ladder cage requirements let existing caged ladders over 24 feet stay in service until November 18, 2036. Replace a cage, well, or ladder section sooner and that section needs a ladder safety system or personal fall arrest system. OSHA has proposed deleting the 2036 date, but it remains in the text.

Key Points

• The rule covers fixed ladders that extend more than 24 feet above a lower level.
• Ladders installed before November 19, 2018 may keep a cage or well. Ladders installed on or after that date may not rely on one.
• Replacing a cage, well, or ladder section triggers a ladder safety system or personal fall arrest system for at least the replaced section.
• OSHA’s April 2026 proposal would delete the 2036 deadline. It is a proposal, not a final rule.

What 1910.28(b)(9) says about fixed ladder cages

The governing text is 29 CFR 1910.28(b)(9), part of OSHA’s walking-working surfaces standard in Subpart D. It applies to fixed ladders that extend more than 24 feet above a lower level. Four rules sit in paragraph (b)(9)(i):

1. (A) A fixed ladder installed before November 19, 2018 must have a personal fall arrest system, ladder safety system, cage, or well.
2. (B) A fixed ladder installed on or after November 19, 2018 must have a personal fall arrest system or ladder safety system.
3. (C) When a ladder, cage, well, or section is replaced, a personal fall arrest system or ladder safety system must be installed in at least the replaced section.
4. (D) By November 18, 2036, all fixed ladders must have a personal fall arrest system or ladder safety system.

Paragraph (b)(9)(iv) allows a cage or well to stay in place alongside either system, provided it does not interfere with how the system works.

The proposal to drop the 2036 date

On April 6, 2026, OSHA published a proposal at 91 FR 17165 (Docket OSHA-2025-0072, RIN 1218-AD73). It would delete paragraph (b)(9)(i)(D). The new-ladder and replacement requirements in (A) through (C) would stay. Comments were due June 5, 2026. OSHA also asked whether the broader requirement should be repealed or revised.

For planning, treat the proposal as a possibility and the regulation as the standing rule. Until OSHA publishes a final rule, the 2036 date is the text you are held to. Check the Federal Register and the OSHA page above before you lock a budget.

What to inventory now

A cage and well count is the starting point, and it is more work than it sounds. Build the list in this order:

• Every fixed ladder over 24 feet. Measure total height above the lower level. OSHA’s 2019 interpretation letter ties the requirement to total height above the lower level, not the length of one ladder section.
• Installation date. Ladders installed before November 19, 2018 and ladders installed after it fall under different paragraphs.
• Current protection. Record whether each ladder has a cage, a well, a ladder safety system, or a personal fall arrest anchor.
• Condition. A cage or well that needs repair is a replacement event. Under (C), that can pull a ladder section into the newer requirement years before 2036.
• Location and use. Note whether the ladder serves a crane runway, a tank, a roof, a pit, or a loading structure, and how often people climb it.

Rail yards and mills tend to have ladders that were added piecemeal over decades. Expect drawings to be missing for some of them.

Multi-section ladders and platforms

Two spacing limits shape the work on tall ladders. If a ladder has fall protection on more than one section, the system must protect the entire vertical distance, and rest platforms must be no more than 150 feet apart. If a ladder still uses cages or wells, its sections must be offset from adjacent sections, with landing platforms at intervals of no more than 50 feet.

These limits matter for budgeting. A tall caged ladder already depends on platforms. Retrofitting the ladder does not remove the platforms from the maintenance list.

When a platform beats a ladder retrofit

A ladder retrofit adds protection to the climb. A platform or access structure changes how people reach the work. Neither is always cheaper, and the right answer depends on the site. These questions help sort the ladders:

• How often is it climbed? A ladder used every shift for routine service work is a candidate for stairs, a platform, or a crossover. A ladder reached twice a year may only need a ladder safety system.
• What do people carry up? Tools and parts are awkward on a ladder. Where workers regularly carry loads, a platform with stair access removes the problem instead of protecting it.
• Is the structure being rebuilt anyway? If the ladder is part of a deck, pit edge, or work area you are already modifying, a replacement triggers (C) regardless.
• What is at the top? If workers do real work at height, they need a working surface, not just a way to climb to one.

Blue SteelCo fabricates steel and aluminum shop equipment in Waxahachie, Texas, including locomotive work platforms, a rolling locomotive ramp platform, small stands and platforms, and crossover bridges. Where a pit or track crossing is involved, our collapsible pit handrails guide covers the related OSHA fall protection rules.

A practical plan before 2036

1. Inventory every ladder over 24 feet this year, using the list above.
2. Sort ladders into three groups: leave as is, add a ladder safety system or anchor, and replace the access with a platform or stairs.
3. Schedule any ladder that needs cage or section repair first. Those jobs trigger (C) when they happen.
4. Get quotes for the second and third groups so budget numbers come from real scopes.
5. Recheck the status of OSHA’s proposal each budget cycle.

Doing this over several years is easier than doing it in 2035 with every other plant competing for the same contractors and fabricators.
