Dear Mr. Faeth:
Thank you for your December 28, 1999 to the Occupational Safety and Health Administration's (OSHA's) Directorate of Compliance Programs. Please be aware that this response may not be applicable to any scenario not delineated within your original correspondence. You had specific questions regarding Fixed Industrial Stairs, 29 CFR §1910.24, and the redesignation of the Access to Employee Exposure and Medical Records Standard, 29 CFR §1910.1020. Your questions and our reply follow.
Question #1: The OSHA [exit route] requirements, [§1910.36(g)(2)], state that the minimum width of any way of exit access shall in no case be less than 28 inches and the OSHA stair requirement, §1910.24(d), requires a minimum stair width of 22 inches. Is an employer out of compliance with this [exit route] standard if the stairs are 22 inches in width?
Reply: Yes, if the stair is an [exit route] component (the exit access, the exit itself, or exit discharge). All stairs, and other approved [exit route] components, must meet the Subpart E, [Exit Routes] standards.1
Furthermore, in order to afford all occupants convenient facilitates for escape, the capacity of an [exit route] (i.e., stair) for any occupied space must be appropriate to the individual building or structure with due regard to the character of the occupancy; the number of persons exposed; the fire protection available; and the height and type of construction of the building or structure. [See paragraph 1910.36(b)(3).] The minimum width permitted for a passageway used as an exit access is, according to [§1910.37(g)(2)], 28 inches; however, most occupancies require additional width based upon the capacity of [exit route] requirements.
The 22 inch stair width requirement applies to both interior and exterior, fixed industrial stairs (i.e., around machinery, tanks, and other equipment; to and from floors, platforms, or pits) when they are used as described in the application paragraphs 1910.24(a) and (b). Where these requirements overlap, the [Exit Routes] requirements would apply.
Question #2: Why did OSHA move §1910.20 to §1910.1020 without updating other 1910 standard references to §1910.1020? There are many references to §1910.20 and the only corrected reference is in the newer Respiratory Protection, §1910.134, Standard. For example, paragraph 1910.120(f)(8)(i) incorrectly directs a reader to §1910.20 instead of §1910.1020.
Reply: In redesignating §1910.20 as §1910.1020, OSHA has simply moved the standard from Subpart C to Subpart Z of the Part 1910 - Occupational Safety and Health Standards. We have not changed or modified the standard language. Your observation correctly identifies OSHA's omission to change the §1910.20 reference language. Our [Directorate of Standards and Guidance] is currently working on a correction notice to rectify this inconsistency. This notice should be published in the Federal Register and become effective this year.
