SECTION 3-Occupancy Hazard
a. Percentage of Occupancy Hazard Classifications(see Worksheet Instructions-tables 1 and 2)
Occupancy Hazard Classification Are Area Total Fire Area Percent of Fire Area
Light Hazard 155224 SF / 157,224 SF x 100 = 98.73 %
Ordinary Hazard Grp 1 2000 SF / 157,224 SF x 100 = 1.27 %
Ordinary Hazard Grp 2(HPCS I& II) 0 SF / 157,224 SF x 100 = 0 %
Extra Hazard Gm 1 (HPCS III) 0 SF / 157,224 SF x 100 = 0 %
Extra Hazard Grp 2(HPCS IV&HH) 0 SF / 157,224 SF x 100 = 0 %
Total must equal 100% I 100 I°%
b. Calculated Fire Flow
Occupancy Hazard Classification Factor Fire Area Fire Flow Bldg Fire Flow
Light Hazard 0.75 x 99 % x 7250 GPM = 5368 GPM
Ordinary Hazard Grp 1 0.85 x 1 °A) x 7250 GPM = 78 GPM
Ordinary Hazard Grp 2 1 x 0 % x 7250 GPM = 0 GPM
Extra Hazard Grp 1 1.15 x 0 % x 7250 GPM = 0 GPM
Extra Hazard Grp 2 1.25 x 0 °A) x 7250 GPM = 0 GPM
