Just because the paint contains combustible products doesn't mean you would need foam.
As far as the pallets, building a covered area and store them outside away from any buildings. Craig L.

I have to elaborate a little on this. The discussion was caused by the case of a client who has a warehouse full of pallets with paint stored in racks. The paint contains combustible liquids. The client wanted to be able to move his racks freely around in the warehouse and doesnot want in-rack sprinklers. He might want to change the layout of the racks from one day to the other. That's why he choose total flooding hi-ex foam and payed the higher price. In that given situation the question came up what he should do with his stacks of idle pallets. Can he safely store high stacks of idle pallets in that same warehouse? Must he limit the idle pallets in the hall to small stacks only and store the bulk of idle pallets elsewhere? Btw, you might want to see this: http://www.youtube.com/watch?v=PK46hFMpetI (Not all the warehouses like this have hi-ex foam; the adjacent warehouses are sprinklered.)
