Milo, I assume you meant "less restrictive".
OSHA can sometimes be applied for equipment access only, where personnel do not normally "occupy" the space - not directly tied to whether the space has "public access".
If you have an enclosure where personnel spend time working, you have a life-safety-egress situation. The Life-Safety Code (NFPA 101) could be applicable, which has stair provisions similar to IBC. (It is referenced from OSHA for exit stairways.)
Of course in Greenland, it depends upon local codes and your contractual requirements as to applicable building codes.

Subject: Re: stairway access to industrial faciliiesHave you tried OSHA 1910? They are more restrictive than IBC.
--Thanks,Milo Zabala, PEI have a project located in the icefield of Greenland. We have a module sitting on a structural steel frame that is supported by columns so It is cantilevered above the snow about 15'. We need to add stairs to access the module and I am wondering if the IBC stairway rise/run of 7/11 applies. The site is remote so there is no public access. On other project, I have noticed that steep ship's ladders are used to access mechanical rooms in buildings that otherwise have 7/11 stairways. is there any way I can justify a steeper rise/run?
