Scaffolds have their own OSHA subpart, their own fall-protection height and their own inspection rule, and the numbers differ from the ones crews recite. This reference explains 29 CFR 1926 Subpart L with paragraph citations: the 4x capacity factor, the 10-foot trigger, the 4:1 tipping ratio, planking gaps and guardrail height.

Fall restraint keeps a worker from reaching the hazard; fall arrest catches a fall already in progress. This reference sets out the hierarchy, a side-by-side comparison, the anchorage rule OSHA actually enforces for restraint, how work positioning differs from both, and where restraint quietly stops being restraint on a real jobsite.

ANSI/ASSP Z359.14-2021 replaced the Class A and Class B self-retracting lifeline labels with Class 1 and Class 2 on August 1, 2023, and changed what the class measures: anchorage position, not stopping distance. Covers both classes side by side, why Class A does not convert to Class 1, and how edge rating differs from class.

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 anchor points must either hold 5,000 lb per worker or be engineered by a qualified person to twice the maximum arresting force, under OSHA 1926.502(d)(15). Confusing arrest anchors with positioning or restraint anchors is how anchorages get under-rated. This guide covers every anchor strength and a worked roof example.

A full-body harness only arrests a fall when it is donned correctly and fitted snug. This guide walks through every step - inspection, untangling, shoulder straps, chest and leg buckles, and dorsal D-ring placement - then covers the fingers-flat fit check and what OSHA 1926.502, 1910.140, and ANSI Z359 require before you tie off.

Tie off without enough room below you and the system stops you only after you have already hit the ground. This guide shows how to calculate fall clearance step by step - free fall, deceleration, worker height, D-ring shift, and safety factor - with worked numbers for a shock-absorbing lanyard versus an SRL under OSHA 1926.502.

A personal fall arrest system is only as strong as its weakest link, and the ABCDs framework is how to make sure no link is missing. This guide explains the ABCDs of fall protection, Anchorage, Body wear, Connectors, and Descent or rescue, covers the OSHA trigger heights, and shows how to calculate the fall clearance you actually need.

OSHA Ladder Requirements: OSHA regulates portable ladders in general industry under 29 CFR 1910.23 (the 2017 Walking-Working Surfaces Final Rule) and in construction under 29 CFR 1926.1053 .

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).
