3-2.3
Aircraft Parking and Refueling Facilities. A minimum fire flow
rate of 3,785 L/min (1,000 gpm) for a 2-hour duration is to be provided for all
such facilities.
3-2.4
Yard and Outdoor Storage. Yard and outdoor storage must be
protected in accordance with NFPA 80A, Protection of Buildings From Exterior
Fire Exposures, NFPA 13, and FM Global Data Sheet 1-20, Protection Against
Exterior Fire Exposure. Aisle widths and separation distances must be
maintained to limit the exposure to nearby buildings and to facilitate manual fire
fighting operations.
3-2.5
Vehicle Parking Areas. A minimum fire flow rate of 1900 L/m (500
gpm) for a 2-hour duration must be provided for all such facilities.
3-3
WATER SUPPLY PRESSURE REQUIREMENTS.
3-3.1
Pressure Required. Pressure required for sprinklered facilities
must be the most demanding pressure of the domestic/industrial demand,
sprinkler demand, or hose stream demand and must be determined by hydraulic
calculations.
3-4
QUANTITIES OF WATER REQUIRED. Requirements for fire
protection water storage are based on the assumption that there will be only one
fire at a time. The quantity of water required is equal to the product of the fire
protection water demand and the required duration. This quantity represents fire
protection requirements only, and must be available at all times. Water supply
for domestic, industrial, and other demands must be added to these
requirements to determine the total amount of water that is necessary at a
facility. If the public water system supplying a facility is reliable, provides a
minimum of two connections (each providing at least 50 percent of the required
capacity), has adequate capacity and pressure to meet water requirements, and
continuous reserve storage capacity at least equal to the required fire protection
water storage, then no separate water storage facility is required.
3-4.1
Total Storage Capacity. The total supply stored for fire protection
purposes must be sufficient to meet the maximum required fire flow demand for
the durations specified in this UFC.
3-4.2
Reduction in Storage Capacity. In computing the fire protection
storage requirement, a reduction in storage capacity is acceptable if an adequate
replenishment source is available. Factors that must be evaluated include the
reliability of the makeup facility, its sustained flow capacity, its method of
operation (automatic or manual), and flow limitations imposed by the capacity of
treatment operations. These factors and calculations must be reviewed and
approved by the cognizant Fire Protection Engineer.
