OSHA vs IBC Fixed Stairway Landing Requirements?

[Enri Code]

The IBC requires that an intermediate landing be provided for stairs that exceed 12 feet in height.

If we have a fixed stairway that has a height of 13 feet and is an OSHA stairway (22" wide and used to access equipment... ) would we still need to provide an intermediate landing or is it clear that we don't need to?

Thank you.

Which IBC and Year?

2015 does 1011.16 answer your question

Sorry, it does not answer my question. We need to stick with stairs. No desire or intention to switch to ladders.
We want to know if we need to comply with intermediate landing or not if it is an OSHA stair.

OSHA just says landings to be provided at top and bottom of stairs.
IBC says landings if stair exceeds 12 feet.

Stair is only for equipment access... to an otherwise unoccupied space. Not for egress.

What is the difference between a stair and ladder,, thought the section addressed equipment access

The way we look at it: is this a part of the building or a part of the equipment? Based on what you said, it is a part of the equipment (remove the equipment, the stairs don't need to be there). In that case, we would not enforce the building code.

That's a good way of framing it. Thank you!

If it's too steep and narrow to be a stair, then it is a ladder and OSHA applies.

 

[Enri Code]

If it's too steep and narrow to be a stair, then it is a ladder and OSHA applies.

It has a 35 degree incline and meets all the other qualifying characteristics according to OSHA 1910.25 STAIRWAYS.

Yes, OSHA clearly distinguishes between ramps, stairs, ship stairs/ alternating tread-type stairs and ladders... there's a difference between them with incline as one differentiator as you pointed out.

Here's figure D-10 of 1910.25 for reference:

The section 1011.16 you referenced is specifically for ladders and not for stairs.
IBC has a different section for stairs as does OSHA which clearly differentiates between stairways and ladders.
I did find the section 505.3 and 1103.2.9 that talks about equipment access and accessibility that helped.

Thank you.

steepness!
