SECTION 3 - Occupancy Hazard
a. Percentage of Occupancy Hazard Classifications(see Worksheet Instructions-tables 1 and 2)
Occupancy Hazard Classification Fire Area Total Fire Area Percent of Fire Area
Light Hazard 780 SF I 2,105 SF x 100 = 37.05 %
Ordinary Hazard Grp 1 885 SF I 2,105 SF x 100 = 42.04 %
Ordinary Hazard Grp 2(HPCS I & II) 440 SF I 2,105 SF x 100 = 20.9 %
Extra Hazard Grp 1 (HPCS III) 0 SF I 2,105 SF x 100 = 0 %
Extra Hazard Grp 2 (HPCS IV& HH) 0 SF I 2,105 SF x 100 = 0 %
Total must equal 100% 99.99 %
b. Calculated Fire Flow
Occupancy Hazard Classification Factor Fire Area Fire Flow Bldg Fire Flow
Light Hazard 0.75 x 37 % x 1500 GPM = 417 GPM
Ordinary Hazard Grp 1 0.85 x 42 % x 1500 GPM = 536 GPM
Ordinary Hazard Grp 2 1 x 21 % x 1500 GPM = 314 GPM
Extra Hazard Grp 1 1.15 x 0 % x 1500 GPM = 0 GPM
Extra Hazard Grp 2 1.25 x 0 % x 1500 GPM = 0 GPM
c. Required Fire Flow with Occupancy Hazard Adjustment 1267 GPM
