OSHA 1910.23 & 1910.28 — How They Apply
OSHA Cat Ladder Requirements
Two OSHA rules govern fixed cat ladders: 1910.23 for construction and 1910.28 for fall protection. We build every OSHA cat ladder to satisfy both, then confirm the exact configuration for your site at drawing review — so the ladder that lands on your roof is the ladder your inspector accepts. Non-compliant access can void insurance cover and trigger regulator citations after any incident.
- 1910.23 — Ladder construction
Rung spacing, 42 in (1.07 m) side-rail extension above the landing, and minimum clearance behind rungs. Our standard 225–230 mm rung spacing is adjusted to the governing band for your jurisdiction.
- 1910.28(b)(9) — Fall protection over 24 ft
Under OSHA 1910.28(b)(9), fixed ladders over 24 ft (7.3 m) require a ladder safety system or personal fall arrest on new installations (in force since 19 November 2018); cages and wells are acceptable on existing ladders only until 18 November 2036. We supply ladder safety systems and PFAS anchor points for post-2018 new installations, and caged ladders for existing-structure grandfathering.
- Material & coating, traced
Q235B hot-dip galvanized 85–100 µm to ISO 1461, SS304/SS316 with mill certificates (EN 10204 3.1), plus aluminium and GRP for corrosive plant.
- Engineer-signed calc, per order
Every cat ladder ships with a structural calculation sheet confirming rung load, fixing spacing and standard compliance before production.
