OSHA fixed ladder requirements come from two standards: 1910.23 sets the design dimensions — rung spacing, clearances, the 42-inch rail extension — and 1910.28(b)(9) sets the fall-protection timeline that ends the ladder cage era on November 18, 2036. This guide maps every date, every dimension, and a worked 30-foot retrofit example.

Fall protection is required at different heights by work type: OSHA construction triggers at 6 feet and general industry at 4 feet, with separate thresholds for scaffolds, steel erection, and fixed ladders. This guide decodes every trigger under 29 CFR 1926.501 and 1910.28 and walks a worked example of assessing a site's fall hazards.

OSHA Guardrail Requirements: OSHA requires guardrail systems - or an equivalent fall protection method - on any open-sided floor, platform, or runway that is 4 feet or more above a lower level in general industry (29 CFR 1910.28), or 6 feet or more above a lower level in construction (29 CFR 1926.501).
