Oregon adopts the federal stairways and ladders subpart, so the employer provides a stairway or ladder at points of access with a break in elevation of nineteen inches or more, keeps access points clear and uses temporary stairs and ladders to the rule (1926.1051), builds and guards stairways with landings, treads, stairrails and handrails (1926.1052), meets the ladder capacity, rung, length, angle, securing, extension above landing, non-conductive side rail, inspection and use requirements (1926.1053, with the Oregon extension ladder rule), and trains each employee using ladders and stairways by a competent person in fall hazards, fall protection procedures, the construction, use, placement and care of stairways and ladders and their load capacities, with retraining as necessary (1926.1060).
