The maximum work-surface height of mobile ladder stands and platforms does not exceed four times the shortest base dimension, without additional support. For greater heights, outriggers, counterweights, or comparable means that stabilize the mobile ladder stands and platforms and prevent overturning must be used;
Under OSHA 1910.23 (d) (2), the minimum perpendicular distance from the centerline of the rungs to the nearest permanent object in the back of the ladder should be 7 inches. With this clearance, you’ll be able to climb the ladder without any potential trip hazards from the building.
Fixed ladders without cages or wells shall have a clear width to the nearest permanent object of at least 15 inches (38 cm) on each side of the centerline of the ladder.
These are meant to protect climbers as they ascend. Previously, a fixed ladder with a cage required a landing platform at a maximum interval of 30’ feet. The new regulations change this requirement dramatically. Fixed ladders without cages must now have a landing platform at maximum intervals of 150’ feet. 1910.28(b)(9)(ii)(B)
All landing platforms shall be equipped with standard railings and toeboards, so arranged as to give safe access to the ladder. Platforms shall be not less than 24 inches in width and 30 inches in length.
Fixed ladders without cages are required to have a landing platform at maximum intervals of 150 feet. Any fixed ladder that requires a personal fall arrest system or ladder safety system must have rest platforms at intervals of no more than 150 feet.
Ladders installed before October 3, 1983, shall be capable of withstanding without damage a minimum concentrated load, applied uniformly over a 3½ inch (8.9 cm) width at the rung center, of 200 pounds (890 N).
Ladder Height: 24 Feet. The easiest—and most publicized—change has to do with ladders that extend 24 feet or more above a lower level. Ladders that are 24 feet or higher can no longer use “safety cages” as a means of protecting workers.

The updated regulations now necessitate a personal fall arrest system (PFAS) or ladder safety system for ladders over 24 ft. For multi-section ladders exceeding this height, platforms or rest points are required. Fixed ladders without cages must have a rest platform every 150 feet at least.
