A. Occupancy Hazard
Al Determine percent of each occupancy hazard in the fire area.
Occupancy Hazard Class Fire Area 1 Total Fire Area Percent of Fire Area
Light Hazard 38,830 SF / 1 38,830 SF x 100 = 100 %
Ordinary Hazard Grp 1 0 SF / 1 SF x 100 = 0 %
Ordinary Hazard Grp 2 0 SF / 1 SF x 100 = 0 %
Extra Hazard Grp 1 0 SF / 1 1 SF x 100 = 0 %
Extra Hazard Grp 2 0 SF / 1 SF x 100 = 0 %
Total Must equal 100% ( 100 % I
A2 Calculate Fire Flow
Occupancy Hazard Class Factor Fire Area Fire Flow Bldg Fire Flow
Light Hazard 1.0 • x 100 % x 4256 GPM = 4256 GPM
Ordinary Hazard Grp 1 1.2 x 0 % x 4256 GPM = 0 GPM
Ordinary Hazard Grp 2 1.3 x 0 % x 4256 GPM = 0 GPM
Extra Hazard Grp 1 1.4 x 0 % x 4256 GPM = 0 GPM

I C. Reduction of Fire Flow - Reductions are based on the following: I
C1 - Reduced by 25% for all Group R Occupancies without fire sprinklers (multiply by .75)
C2 - Reduced by 25% for a NFPA 72 Fire Alarm System (multiply by .75)
C3 - Reduced by 75% for NFPA 13 Automatic Sprinklers (multiply by .25)
