Arresting the fall is only half the system: OSHA requires employers to provide for prompt rescue or assure self-rescue whenever personal fall arrest is used. This guide explains the duty in 1926.502(d)(20) and 1910.140(c)(21), what OSHA letters say about 911-based plans and suspension time, and how to build the capability.

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).
