Question: What if the doorway described in §1910.25(b)(5)(ii) and shown in figure D-7 is perpendicular to the direction of travel and opens onto the landing? Does the same dimension apply to this condition?

Answer:

Yes. As figure D-7 illustrates, Section 1910.25(b)(5) requires that a platform be provided when a door or a gate opens directly onto a stairway. For platforms installed after January 17, 2017, the final rule also requires that employers ensure the swing of the door or gate does not reduce the "effective usable depth" of the platform to less than 22 inches (§1910.25(b)(5)(ii)). The preamble to the final rule describes “effective usable depth” as the portion of the platform beyond the swing of the door where a worker can stand when opening the door (82 FR 82557). The provision applies equally to stairway doors that are perpendicular to the direction of travel.
