FIRE PUMPS. Fire Pumps, when required, are a part of the project
scope. Evaluate the fire protection requirements to be able to utilize a single set
of pumps in lieu of providing pumps for multiple hangars. The design agency
should provide for adequate space to accommodate the pumps and facilitate
their maintenance. Consideration should be given to accommodate the pumps in
a separate building.

STRUCTURAL SYSTEM PROTECTION. NFPA 409 requires that
all main steel structural columns in the hangar bay be made fire resistant using
listed materials and methods to provide a fire resistive rating of not less than 2
hours.
5-10
WATER SUPPLY AND FOAM STORAGE. The water supply must
be capable of maintaining water discharge for the combined low-level sprinkler
systems at the design rate for a minimum of 45 minutes. The foam storage and
water quantities are based on the size of the hangar. The larger the hangar, the
larger the quantity of AFFF and water required. Refer to UFC 3-610-01 for
redundant foam storage, pumps, and other fire protection requirements.
5-11
LIFE SAFETY. The fire protection engineer must review final floor
plans for compliance with NFPA 101. For conflict resolution contact the Chief
Fire Protection Engineer at Naval Facilities Engineering Command, 1322
Patterson Ave, SE, Suite 1000, Washington Navy Yard, DC 20374-5065.
