The procedure for determining specific fire flow demands and duration within a
range is provided in Appendix C. This procedure must be followed to determine
the minimum requirements for facilities that are not fully sprinklered.
When the required fire flow demand exceeds 7,570 L/m (2,000 gpm), a cost and
benefit analysis must be conducted to determine if additional fire protection
systems, features, or design changes that provide more favorable factors, such
as type of construction or sprinkler protection, are more cost effective than
providing the required fire flow.
Hose Stream Demand for Unsprinklered Special Facilities.
Special requirements may apply to certain facilities. Such facilities include ship
berthing and drydock facilities, family housing, petroleum oil lubricant (POL)
areas, aircraft parking and refueling areas, and vehicle and yard storage. See
Ship Berthing and Drydock Facilities.
Refer to paragraph 6-13 for water demand requirements for ship berthing and
The water demand for unsprinklered family housing must be as follows:
One-story - 1,900 L/min (500 gpm) for 90 minutes.
Two-story - 2,840 L/min (750 gpm) for 90 minutes.
Three-story and above - 3,785 L/min (1,000 gpm) for 90 minutes.
Petroleum Oil Lubricant (POL) Areas.
POL areas must conform to the following:
Aboveground Atmospheric POL Tanks. Table 3-1 provides fire
flow rates for non-pressurized POL tanks.
Aboveground Pressurized POL Tanks. Table 3-2 provides fire flow
rates for pressurized POL tanks.
