Is the space below the raised floor in a semiconductor facility a PRCS?

I spent several years working at semi-conductor facilities (the Cincinnati SUMCO plant was one of the finest!) and it was world’s apart from a chemical facility.  When I worked in chemical plants we always used to say… “this ain’t no chocolate factory”.  But when I arrived at SUMCO I swear it was cleaner than any…...

One of the topics we have debated about 1910.146 is whether (c)(5) and (c)(7) entry methods could be used simultaneously on the same space.  I was a resounding “No” but since we could never get an official answer from OSHA, there were many in our profession who felt it was acceptable to use (c)(5) and…...
