Chris, Thanks for pointing out the word "Not" in 16.1.10.1. I swear I've read it 100 times that it was required.

It does not defer to ch13 exactly on all matters, just says the protection is the same as... '10 - 16.2.1.2.2 The protection criteria in Chapter 13 shall be acceptable for storage of Class I through Class IV commodities up to and including 12 ft (3.7 m) in height. (See Table 13.2.1 for specific Class I through Class IV storage height protection criteria.) Again, telling you to see a specific chapter and really only talking about densities. '10 16.2.1.3 is for all racks over 12' so not applicable. 16.2.1.3.3 Multiple-Row Racks - Storage Height Over 12 ft (3.7 m) Up to and Including 25 ft (7.6 m) Without Solid Shelves. Further supports multi-row under 12' is ch13. The flue stuff appears in 16.1.10. I don't see any exception or reference back to ch13. So I think 16 is still the relevant chapter. But you get where you/they want to be with '10 - 16.1.10.1 In double-row and multiple-row racks without solid shelves, a longitudinal (back-to-back clearance between loads) flue space shall NOT be required. So no longitudinal flue per ch16 and OHII with potential area modifiers per ch13.

The exception being when tires are stored. Based on this, the scenario you're talking about sounds like multi-row racks. As long as you are directed back to chapter 13 multi-row racks are acceptable, so no flue space would be required.

(CSFD) Sent: Wednesday, July 25, 2012 11:16 AM To: [email protected] Subject: Miscellaneous Storage (Chapter 13) and flue spaces Is it the intent of Chapter 13, Miscellaneous Storage, to not be concerned with, and thus allow the removal of, longitudinal flue spaces between double row racks? We have a facility with Class III commodities stored on single and double row racks to 12 feet. They (facility, not contractor) wish to push the double row racks back to back and not provide a flue space. Their reasoning is Chapter 13 doesn't mention anything about flue spaces, thus they don't need them. I reference 16.1.10.1 where it states a 6-inch longitudinal flue space is required. Their rebuttal is that the 12-feet of storage is not considered "high pile" storage and therefore this section does not apply and again falls back to Chapter 13. Make sense? Any thoughts?
