OSHA 1910.27 Fixed Ladders
The dimensional numbers your EHS team will check, side by side. We build to the strictest applicable value on every ladder.
| Requirement | OSHA 1910.27 | Cal/OSHA §3277 | ANSI A14.3 |
|---|---|---|---|
| Rung spacing | 10–14 in (25–36 cm) | ≤12 in (30 cm) | 10–14 in (25–36 cm) |
| Climbing width | ≥16 in (41 cm) | 16 in (41 cm) | ≥16 in (41 cm) |
| Rung-to-wall clearance | 7 in minimum | Per Title 8 | 7 in minimum |
| Fall protection trigger | >24 ft: PFAS or ladder safety system | >24 ft | >24 ft |
| Landing platforms | Every 50 ft max | Per Title 8 | Every 50 ft max |
| Cage start height | 7–8 ft above grade | 7 ft | 7 ft |
| Cage above landing | 42 in | 42 in | 42 in |
| Clearance at 76° / 90° | Per 1910.23(d) | 36 in / 30 in | Per A14.3 |
Europe & UK
BS 4211 & EN ISO 14122-4
BS 4211:2005+A1:2015 for permanently fixed ladders, EN ISO 14122-4 for machine-access, and HSE / Ministry of Labour routes for regulated sites.
Asia-Pacific
AS 1657 & SS 553
Australian and Singaporean markets use AS 1657 (fixed platforms, walkways, stairways and ladders) and SS 553. We build to the local standard and issue the matching DoC.
Which standard applies?
- USA / Canada — OSHA 1910.27, ANSI A14.3, Cal/OSHA Title 8
- UK — BS 4211 + HSE Work at Height Regs 2005
- EU — EN ISO 14122-4, machine directive context
- Australia — AS 1657
- Singapore — SS 553 / Ministry of Labour

Paperwork That Passes Inspection
Compliance DoCs: DoC, MTC, Calcs
- Declaration of Conformity (DoC) to your standard
- Material Test Certificates — EN 10204 3.1
- Structural calculations with dimensional checks
- Welding Procedure Specifications (WPS)
- Surface treatment certificates (HDG per ISO 1461)
PFAS point to flag on every project
For ladders installed after Nov 19, 2018 over 24 ft, a cage alone no longer satisfies OSHA 1910.27 — you need a PFAS or ladder safety system. We flag the trigger point on your drawing and quote the PFAS-ready rail so there is no surprise during inspection.
Common questions
USA: OSHA 1910.27 + ANSI A14.3; UK: BS 4211; Europe: EN ISO 14122-4; Australia: AS 1657:2018; Singapore: SS 553:2016. Tell us the destination and we build and document to the right standard.
Yes — most of our ladders are designed to the strictest applicable requirements and documented against several standards in the order-level DoC. Welding follows ISO 5817 Level C with ISO 9606-1 certified welders and ISO 15614-1 WPQR.
Yes — every shipment includes a Declaration of Conformity (ISO 17050-1), MTC (EN 10204 3.1), weld inspection records and structural calculations, free of charge. Third-party inspection is available on request.
Since November 19, 2018, new fixed ladders over 24 ft must have a personal fall arrest system (PFAS) or a ladder safety system — cages alone no longer count for new installs. Existing caged ladders have a transition period until November 18, 2036.
EN ISO 14122-4 is the harmonized standard for machine access under the Machinery Directive, but fixed building ladders have no mandatory CE certification scheme. We state "complies with EN ISO 14122-4" and issue order-level DoCs instead of claiming CE.
