Not that I want to get in the way of a distinguished FPE, but it
would seem to me that you would treat this more as an obstruction or
mezzanine. Rack storage you are trying to protect a single entity and
are using multiple levels of protection, so balancing would be
appropriate. In this case, you are trying to protect a space below
conveyors, which would fall more like a mezzanine and require a
separate calc. However, if your distinguished FPE is with a
distinguished FPE firm and this if for a large national account,
either they or the insurance company may have their own ideas.
At 11:39 AM 2/14/2009, you wrote:
In a storage facility (similar to fed ex or UPS) with large
conveyors that are to be protected on a separate system, do you have
to balance the calcs with the overhead system like you do on a rack system?
FYI - there is a distinguished FPE involved but he is out of pocket
for the weekend and I need to make headway on this project..

If it is a high rise and these "closets" are not part of a continuous
rated shaft how could you justify penetrations through the floors?
