*BOCA is an abbreviation for Building Officials and Code Administrators which is no longer in existence. The basic
design of the stairway shown here is still popular as an OSHA approved fixed industrial stair which has a more
comfortable (7/11-rise/run) 32 degree angle as opposed to the more conventional 45 degree OSHA stair. Because
of its more gradual rate of rise, the BOCA stair does require more horizontal floor space.

OSHA STANDARD 1910.25 STAIRWAYS
Walking-Working Surfaces and Personal Fall Protection Systems Final Rule
Frequently Asked Questions
The intent of OSHA’s Walking-Working Surfaces standard, 29 CFR Part 1910, Subpart D & I, is to increase the
protection of general industry employees and employers from hazards associated with walking-working surfaces. The
rule making will significantly reduce the number of worker deaths and injuries that occur each year resulting from
workplace slip, trip, and fall hazards. The final rule was published on November 18, 2016, and became effective on
January 17, 2017. Some requirements in the final rule have compliance dates after the effective date and will be
discussed in further detail below. This final rule and the associated preamble, providing more detailed explanation of
the rule, is available on the Federal Register website at 81 FR 82494, Walking-Working Surfaces; Personal Protective
Equipment; Final Rule, November 18, 2016.
OSHA requirements are set by statute, standards, and regulations. The Agency’s interpretations explain these require-
ments and how they apply to particular circumstances, but they do not create additional employer obligations. Note
that our enforcement guidance may be affected by legislative or rule making changes to OSHA requirements. Also,
from time to time we update our guidance in response to new information. To keep apprised of such developments,
you can consult OSHA’s website at http://www.osha.gov.
This webpage provides guidance, in a question and answer format, regarding OSHA’s Final Rule, Walking-Working
Surfaces and Personal Protective Equipment, 29 CFR Part 1910, Subpart D and I. These Frequently Asked Questions
(FAQs) are divided into five sections: general questions, rope descent system (RDS) questions, outdoor advertising
questions, residential roof questions, and agricultural operation questions.
Standard Stairs
Does the exception to the 9.5-inch riser height and 9.5-inch tread depth requirements for stairs installed before
January 17, 2017 (§19210.25(c)(5)), also apply to stairs designed and fabricated, but not yet installed, by that date?
Stairs with design drawings issued for construction or that were in fabrication before January 17, 2017, but not
installed, will be in compliance if they met the previous requirements for standard stairs.
Under the previous standard, stairs with a handrail that doubles as a stair rail could have a rail height of 30 to 34
inches. If an employer's stairs were installed prior to January 17, 2017, must the rails have a minimum height of
36 inches if the stair rail doubles as a handrail?
The final rule does not affect stair rail systems and handrails installed before January 17, 2017 that were in com-
pliance with the requirements in the old standard.
Does the requirement that standard stairs have a slope between 30 to 50 degrees apply to stairs installed after January
7, 2017. Therefore, the maximum angle for standard stairs is 45 degrees.
Yes. The final rule limits the maximum rise height and minimum tread depth to 9.5 inches for standard stairs installed
after January 17, 2017. Therefore, the maximum angle for standard stairs is 45 degrees.
Are stairs installed after January 17, 2017, that have an angle of 50 degrees considered to be ships stairs?
The final rule defines ship stairs as “a stairway that is equipped with treads, stair rails, and open risers, and has a slope
of 50 to 70 degrees.” Ship stairs must also comply with §1910.25(b) and (e), such as a minimum tread depth of 4
inches, a minimum tread width of 18 inches, and a vertical clearance above any stair tread to any overhead
obstruction of at least 6 feet 8 inches.
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?
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.
Are fixed stairs attached to the exterior of tanks required to comply with the requirements of §1910.25(b) or would
those stairs fall under the exemptions in §1910.25(a)?

The exception from the stair requirements in §1910.25(a) only applies to stairs serving floating roof tanks, stairs on
scaffolds, stairs on self-propelled motorized equipment, or stairs designed into machines or equipment. For stairs on
the exterior of other tanks, employers would have to ensure they comply with the requirements in §1910.25(b) and (c).
Would winding stairs attached to tanks be required to meet the requirements in §1910.25(d) for spiral stairs?
No. Section 1910.21(b) defines spiral stairs as a "series of treads attached to a vertical pole in a winding fashion,
usually within a cylindrical space" (emphasis added). Winding stairs attached to tanks do not have vertical poles;
therefore, they are not spiral stairs and must meet the requirements of §1910.25(b) and (c).
Based on the height requirements for stair rails and handrails and the requirements in Table D-2, are both stair rails
and handrails required on stairs that have two open sides and are less than 44-in. wide?

Yes. Section 1910.28(b)(11)(ii) Table D-2 contains a printing error, which OSHA will correct in a published notice.
For each flight of stairs with two open sides and a width of less than 44 inches, column 4 of Table D-2 should state
