Ship Berthing and Drydock Facilities. See section 21.0 for water
demand requirements for ship berthing and drydock facilities.
The water demand for unsprinklered family housing
shall be as follows:
One-story - 500 gpm (1,920 L/min) for 90 minutes.
Two-story - 750 gpm (2,820 L/min) for 90 minutes.
Three-story and above - 1,000 gpm (3,780 L/min) for 90 minutes.
POL areas shall conform to the following:
a) Aboveground Atmospheric POL Tanks.
Table 188.8.131.52.9 provides
fire flow rates for non-pressurized POL tanks.
b) Aboveground Pressurized POL Tanks.
Table 184.108.40.206.b provides
fire flow rates for pressurized POL tanks.
Aircraft Parking and Refueling Facilities. A minimum fire flow rate
of 1,000 gpm (3,780 L/min) for a 2-hour duration is to be provided for all
Yard and Outdoor Storage. Yard and outdoor storage shall be
protected in accordance with NFPA 80A, Protection of Buildings From Exterior
Fire Exposures, NFPA 231, and FM Loss Prevention Data Sheet 1-20, Protection

shall be the pressure required to meet
the total demand and shall be
determined by hydraulic calculations.
The total demand is the required sum of
the domestic demand, sprinkler demand,
and hose stream demand.
