Guidelines for stairway type ladders are as follows:
- Be positioned such that their bottom step is not more than 24 inches above the scaffold supporting level.
- Be provided with rest platforms at 12 foot maximum vertical intervals.
- Have a minimum step width of 16 inches, except that mobile scaffold stairway-type ladders shall have a minimum step width of 11 1/2 inches.
