We just rented some scaffolding from the Orange Box to do some work onstage, and it didn't come with a ladder, just the rungs built into the upright. It did come with rails and toeplates, however. I guess rental houses aren't required to provide OSHA-compliant equipment.
Using the rungs to climb is not a problem if the spacing is proper. Older scaffold with spacing over 1 foot does not meet the requirement.
