There is limited prior research related to protection of storage under ceilings with slopes steeper than 2/12. Previous studies exist from FM Global, University of Maryland/Custom Spray Solutions, the Fire Protection Research Foundation, and National Fire Sprinkler Association (NFSA), but there are still many open questions related to the protection criteria for storage under sloped ceilings. The questions include, but are not limited to; sprinkler activation pattern relative to fire source location, and optimal sprinkler installation orientation. There are many different parameters related to this design challenge. Some of the key parameters include the slope of the ceiling, the commodity...
