NFPA 61 2008
(OP)
Does section 6.2 of NFPA 61 ("Enclosure Requirements") apply to silos (interior to a building) or is a silo a piece of equipment? Intuitively, it would seem that a silo is equipment, but Exception No. 2 under 6.2.1.2 specifically seems to pertain to silos (i.e. "Bins and Silos"). Chapter 7 ("Equipment") does not list any provisions for silos, and Section 4.5 has precious little info on silos.
I am trying to get a handle on the design philosophy and intent of NFPA 61. It seems to be saying that you do not need to vent or suppress a new or modified silo in an existing enclosure if it is "not practical". To me this seems to be an extraordinarily broad provision.

would say it is a building/ structure

3.3.36* Building. Any structure used or intended for supporting or sheltering any use or occupancy.
3.3.271* Structure. That which is built or constructed.

The exception in question applies to a building ('Enclosure') given in 6.2, but not to the 'Equipment Requirements' given in 6.3. In my eyes, a silo therefore is not granted the "not practical" exception.
