OSHA 1926.1053 Ladders (Construction): what it requires and the equipment it names
29 CFR 1926.1053 is the construction ladder rule in Subpart X: design loads, rung spacing, the angle and extension of portable ladders, securing and footing, inspection by a competent person, the three-point climbing rule, and cages, wells, ladder safety devices or self-retracting lifelines on fixed ladders that climb 24 feet or more. We sell nationwide; ships in 1–2 business days; most orders arrive in 3–7 business days.
The plain answer
29 CFR 1926.1053 requires construction ladders to support at least four times the maximum intended load (3.3 times for extra-heavy-duty Type IA, and fixed ladders two loads of 250 pounds per section), to have rungs spaced 10 to 14 inches apart, to be used at about a 4-to-1 angle, to extend 3 feet above the landing or be secured with a grab device, to be used only on stable, level surfaces or secured, not tied together, not loaded beyond their rating, and to be inspected by a competent person periodically and after any occurrence that could affect safe use, with defective ladders tagged and withdrawn.
For fixed ladders it requires 7 inches of clearance behind the rungs, 30 inches in front (24 with a deflector), rails or grab bars extending 42 inches above the landing, cages, wells, ladder safety devices or self-retracting lifelines where the climb is less than 24 feet but the top is more than 24 feet above a lower level, and where the climb is 24 feet or more either a ladder safety device, a self-retracting lifeline with rest platforms every 150 feet, or a cage or well with sections of 50 feet or less. It applies to all construction employers; general industry uses 1910.23.
The equipment it names is portable and fixed ladders, job-made ladders, ladder safety devices (the carrier, sleeve and harness connection with a connection of 9 inches or less), self-retracting lifelines, cages and wells, rest platforms, and the harness the climber wears with a ladder safety device.
What the rule says

29 CFR 1926.1053(a)(1): Ladders support without failure at least four times the maximum intended load (3.3 times for extra-heavy-duty Type IA metal or plastic ladders); fixed ladders support at least two loads of 250 pounds each between any two consecutive attachments plus anticipated loads from ice, wind and rigging; ladders built to Appendix A are deemed to meet the requirement.
29 CFR 1926.1053(a)(2)-(3): Rungs, cleats and steps are parallel, level and uniformly spaced, 10 to 14 inches apart on portable and fixed ladders (8 to 12 inches on step stools, 8 to 18 inches on the base section of extension trestle ladders).
29 CFR 1926.1053(a)(4)-(7): Minimum clear width between rails of 11.5 inches on portable ladders and 16 inches on fixed ladders; rungs of fixed and job-made ladders are skid resistant; ladders are not tied or fastened together unless designed for it; a metal spreader or locking device holds a stepladder open.
29 CFR 1926.1053(a)(8)-(13): Fixed ladders: no more than 90 degrees from horizontal; 7 inches minimum clearance from the rung centerline to the nearest object behind (4.5 inches for elevator pit ladders); 30 inches clearance on the climbing side (24 with a deflector device); 15 inches each side of the centerline where no cage or well; step-across distance of 7 to 12 inches; grab bars and side rails that extend 42 inches above the landing.
29 CFR 1926.1053(a)(18)-(21): Fixed ladders are provided with cages, wells, ladder safety devices or self-retracting lifelines where the climb is less than 24 feet but the top is more than 24 feet above lower levels; where the climb is 24 feet or more, a ladder safety device, or self-retracting lifelines with rest platforms every 150 feet, or a cage or well with ladder sections of no more than 50 feet and offset landing platforms; cages and wells meet the dimensions in the paragraph.

OSHA 1926.1053 Ladders (Construction) questions
What are the OSHA standards for portable ladders? In construction, 1926.1053: rated for four times the maximum intended load, rungs 10 to 14 inches apart, set at a 4-to-1 angle, extended 3 feet above the landing or secured with a grab rail, used on stable level footing or secured, kept clear top and bottom, never moved while occupied, never climbed on the top step or cross bracing, inspected by a competent person, and climbed facing the ladder with one hand free.
Does OSHA require fall protection for portable ladders? No paragraph of 1926.1053 requires fall protection on a portable ladder; the rule relies on placement, securing and three-point climbing. Fall protection is required on fixed ladders by 1926.1053(a)(18) and (19): a cage, well, ladder safety device or self-retracting lifeline where the top is more than 24 feet up, and a ladder safety device, SRL or cage with 50 foot sections where the climb is 24 feet or more.
How far above the support point should a ladder extend when accessing a roof? At least 3 feet above the upper landing surface, under 1926.1053(b)(1); where the ladder is too short, it is secured at the top to a rigid support that will not deflect and a grab rail or similar device is provided, and the extension may never let the ladder deflect under load and slip off its support.
What is the 4-to-1 rule for ladders? 1926.1053(b)(5)(i): a non-self-supporting ladder is set so the horizontal distance from the top support to the foot is about one-quarter of the working length of the ladder, so a ladder with 16 feet between foot and top support has its feet about 4 feet out from the wall.
How much weight should a portable ladder be able to support? At least four times the maximum intended load without failure under 1926.1053(a)(1), or 3.3 times for an extra-heavy-duty Type IA ladder; the duty rating on the manufacturer's label (Type III 200 lb, II 225, I 250, IA 300, IAA 375) is the maximum intended load, and (b)(3) prohibits loading beyond it.
What is designed to prevent falls from a fixed ladder and consists of a carrier, sleeve, connector and harness? A ladder safety device, under 1926.1053(a)(22) to (24) and the Subpart X definitions: a carrier (rigid rail or flexible cable) mounted to the ladder, a safety sleeve that travels on it and locks in a fall, and a connector of 9 inches or less to the front D-ring of a full body harness, tested to survive an 18 inch drop of a 500 pound weight.
