If I store only steel items, in steel racks with flow through shelves (made of steel), do I need in-rack sprinklers?
It seems logical that I could use only ceiling sprinklers in this example. The logic is that the all steel construction has zero fuel for a fire and acts as a good "fire break" against the spread of fire within the building.
Let me know if you'd agree or if I'm off base here. Thanks in advance.

A couple factors come in the play with determining the need for in-rack automatic sprinklers. I know of several insurers that treat steel on steel racks (without wooden pallets) effectively a Class 0 Commodity, though you won't find that in 13.

You would just need to use a fire sprinkler design that requires ceiling only protection.

Need additional information to provide proper guidance, including building height, commodity to be stored, number of shelves, storage arrangements. This is area of NFPA 13 that is extremely prescriptive and deviations are typically not accepted.

I find it difficult to believe that there wouldn't be combustibles and that the building would be able to maintain that state through its life. If we're talking steel pipe on pipe racks then it's easy, but if these are pallet racks with open shelves we have to consider how they're stored and organized. While the commodity itself is non-combustible it doesn't make sense for large pieces of steel to be processed without an efficient means to load/unload the shelves and small pieces risk falling through open shelves. Would there be delivery packaging materials and waste of the same? Would organization means include combustible pallets, cardboard boxes, plastic bins, etc. or for non-combustible intent metal pallets and wire baskets? The difficulty is in achieving and maintaining the minimal combustibles.

Working for an insurance company, I would even consider that you don’t need sprinklers at the ceiling… unless there is something else to burn (as a combustible roof for example).
