If there's a builder's show or RV show in it, you've got shielded fires like
modular plants, EH.

Depends upon the use of the hall. Large facilities have capacity for shielded
fire scenarios from exhibits (RV's, boats, built displays) that approximate
extra hazard. A general rule of thumb for large exhibit halls has been 0.30
over 100 times the clear height.

Dave, you are likely thinking of the old UBC Standard 9-1 that had table 1.4.7
with all sorts of occupancies correlated with NFPA hazard classifications.
That table indeed allowed an exhibition hall to be OH2. I ran into this when I
Plan Not Approved the exhibition hall designed for OH2 years
