For fixed industrial stairs, OSHA requires in paragraph 1910.24-(c): "Fixed stairways shall be designed and constructed to carry a load of five times the normal live load anticipated but never of less strength than to carry safely a moving concentrated load of 1,000 pounds." UBC requires exit stairways to be designed for 100 psf or a concentrated load of 300-pounds. If you are installing a stair in an industrial building which could also act as an exit stairway, how is OSHA to be applied? Are the loads given by OSHA to be applied as "working loads" at basic allowable stress or to be compared to yield or ultimate strengths? For a live load of 100 psf, do they really mean to design the stair for 5 times 100 psf? If the stair is not an exit stair, what does "normal live load anticipated mean"? I find the inconsistency in these provisions rather confusing and difficult to apply.
