protection and life safety features. When completing third party projects the content of
the analysis will include an analysis and drawing that provides the following information:
Type of occupancy.
Type of construction.
Location of fire-rated walls, doors and dampers, including those for
hazardous areas.
Exit travel distances.
Horizontal exits.
Exit signs and emergency lights.
Occupant load/exit unit widths.
Automatic extinguisher systems.
Fire detection/alarm devices.
Sprinklered areas (as appropriate)
3-4.1.6 Fire extinguishers shall be provided per UFC 3-600-01 - which states to follow
NFPA 101 and NFPA 10. A fire extinguisher is also required in arms vaults per
paragraph 4-2.11.9. Per NFPA 10 maximum travel distance to an extinguisher is 75 feet.
3-4.1.7 If a facility authorization includes a SCIF, the SCIF will have a single
controlled point of entry, most likely with an electronic lock. If necessary, a separate exit
(or exits if two are required) can be provided to satisfy life safety/exiting requirements.
The USAR security personnel will want any such exits to include an audible alarm, and
possibly a short delay, for security reasons. No hardware should be provided on the
exterior side of such exit doors.

Fire Sprinkler System
3-4.2.1 Fire sprinkler system design for USAR projects is normally accomplished
through a performance specification, with the contractor s design engineer responsible
for a detailed system design. The design criteria identified in UFC 3-600-01 must be
conveyed to the contractor s designer in the contract documents. Note that the hose
stream and design areas for various hazard classifications are more stringent than
NFPA 13 requirements.
3-4.2.2 Identify design densities for water flow and sprinkler types on a room-by-room
basis so hydraulic calculations may be performed. Flow test data must be provided for
the contractor to determine if the cost of oversized piping will need to be included in the
bd.
3-4.2.3 UFC 3-600-01 requires that every portion of a sprinkled building be sprinkled;
it does not allow exceptions for computer or electrical rooms, or arms vaults.
3-4.3
Fire Alarm System
3-4.3.1 An addressable Class B fire alarm system will be provided, consisting of
manual break glass stations at exits, combination horn/visual signals located in
