4.7 FIRE PROTECTION AND SAFETY
4.7.1 FIRE PROTECTION SYSTEMS
a. Automatic sprinkler and gaseous extinguishing system piping layouts shall not be
designed; i.e., a piping plan will generally not be provided to show new work. Such a
plan may be necessary to indicate existing piping sizes and locations or to show pipe
routing where interference problems exist. In i nstances where architectural and interior
design features are critical (e.g. lobbies, clubs, BEQ/BOQ rooms), it may necessary to
show sprinkler head or piping locations. A schematic riser diagram is required and points
of connection must be identified.
b. Describe fire detection and alarm systems including location of detectors, manual
stations, audible devices, control panel, etc. Number of conductors shall not be indicated
unless required to ensure proper interface with existing systems or for unusual or
complex systems.
c. Indicate location of water supply main entrance to building and detail of sprinkler
valves. Also indicate location and details of gaseous extinguishing system equipment
and supplies; show piping to the extent required by space li mitations, where potential
interference problems may occur, etc.
d. Refer to the latest edition of MIL-HDBK-1008 Fire Protection for Facilities
Engineering, Design, and Construction for specific applications and requirements for
various types of fire protection systems. Such systems must meet applicable NFPA
standards.
e. Provide the following information about sprinkler systems:
(1) Authority for installation of sprinkler systems.
(2) Hazard classification of occupancy and whether system will be hydraulically
calculated or follow the pipe schedule method.
(3) For hydraulically designed systems, state density and area of application as
well as water supply available at point of connection (static pressure and residual
pressure at design flow). This data must be based upon flow tests at or near the point of
connection and must appear in the Basis of Design.
(4) Identify type(s) of automatic sprinkler system(s) involved, i.e., wet -pipe, dry-
pipe, preaction and/or deluge. Indicate areas to be protected and each type of system
proposed. If the use of a preaction or deluge system is contemplated, contact the PM for
guidance before proceeding with design.
(5) Provide fire pump data if applicable.
