4. The protection of combustible commodities six hundred forty
centimeters (640 cm) and seven hundred sixty centimeters (760 cm) in
height will require up to thirty percent (30%) increase in the densities
listed in the above table. Commodities piled more than seven hundred
sixty centimeters (760 cm) in height will require multi-level sprinkler
application.
5. Sprinkler system protecting combustible commodities shall be
designed and installed to discharge the required water density within
the following prescribed minimum areas, except that areas shall be
not less than three hundred seventy square meters (370 m 2 ) in
calculating water flows when densities of less than one thousand one
hundred forty-one liters per minute per square meters (1,141L/(min . m 2 ))
are specified.
