They like it, but 1 1/4" pipe sure isn't 1 1/2" nominal pipe.  

One other problem with the OSHA standard is 1910.23(e)(3)(i) which deals
with wood railings. It says the rails shall be at least 2x4 stock. If
this were actually done, it would violate the maximum perimeter
dimensions allowed in the various building codes for "grippability".
