If you look at the annex material, fire control using the 12.8.1 protection scheme may not be achieved. Which makes you wonder how it came to be a design option. Something to consider. All the chapter 16 options use the schemes A,B, or C for plastic containers.

It looks like your scenario would be class IV density. You can have 13,750 gallons IIIB before chapter 16 kicks in. -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Jeremy Frazier Sent: Friday, May 22, 2015 1:48 PM To: [email protected] Subject: RE: NFPA 30 - Class IIIB Plastic Containers What is the total quantities? Because unless there is a lot of them, you probably don't need to go that far in 30. Unprotected flammable liquids is ordinary grp 2. -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Gregg Fontes Sent: Friday, May 22, 2015 10:22 AM To: [email protected] Subject: NFPA 30 - Class IIIB Plastic Containers Scenario, quarts, gallons, and 5 gallons plastic containers of a Class IIIB liquid (i.e. motor oil, gear oil, hydraulic oil) stored 5' high on pallets for shipment to typical retail automotive stores. The quarts and gallon containers will be in cardboard boxes. The 5 gallons will be stacked two high on a pallets. First, would these containers be considered IBC's (intermediate bulk containers per 3.3.12.2 - 2015 edition)? If so, then I assume Table 16.5.2.9 would apply? If not considered IBC's, what Table would apply, if any?
