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 14571 SF / 16,866 SF x 100 = 86.39 %
Ordinary Hazard Grp 1 2271 SF / 16,866 SF x 100 = 13.46
Ordinary Hazard Grp 2 (HPCS I & II) 24 SF / 16,866 SF x 100 = 0.14
Extra Hazard Grp 1 (HPCS III) 0 SF / 16,866 SF x 100 = 0
Extra Hazard Grp 2 (HPCS IV& HH) 0 SF / 16,866 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 86 0/0 x 3500 GPM = 2268 GPM
Ordinary Hazard Grp 1 0.85 x 13 % x 3500 GPM = 400 GPM
Ordinary Hazard Grp 2 _ 1 x 0 % x 3500 GPM = 5 GPM
Extra Hazard Grp 1 1.15 x 0 % x 3500 GPM = 0 GPM
Extra Hazard Grp 2 1.25 x 0 % x 3500 GPM = 0 GPM
c. Required Fire Flow with Occupancy Hazard Adjustment 2673 GPM
SECTION 4- Minimum Number of Fire Hydrants Required
Refer to Table C105.1 below (2010 OR Fire Code, Appendix C) for the minimum number of hydrants required.
