The 1997 ICBO UBC (1003.3.3.6) and the 1999 BOCA NBC (1022.2.4)
are even more lienient than the ASTM E985 shown above.  They each
allow 1.25" *outside* diameter pipe rails.  Who controls? A Pipe 1" std.
would meet the UBC regulations with a 1.315 outside diameter but not the
OSHA regulations.  Should this be allowed to be built or not?

Who controls in a disagreement with a local building code and OSHA?
Can a local government allow construction that is less strict than OSHA?
Exactly how much authority does OSHA have?  I know they can inspect
