6-9.6.4 Floors/Walkways
The finished floor elevation should be 6 in (152 mm) or more above grade or the
adjacent walkways, unless the facility is located on a raised island. If the facility is on
an island, the minimum finished floor elevation will be the elevation of the island.
Provide floors and walkways with anti-skid surfaces. Anti-fatigue mats should be
provided at all security personnel posts to relieve fatigue and discomfort from standing
for long periods of time.
6-9.6.5 Environmental Control
Provide heating and cooling appropriate for personnel, the electronic and electrical
systems or fixtures, and the security support equipment. The HVAC requirements
should be based on existing service design guidance and installation requirements.
Consider protection from chemical or biological agents used during an attack based on
the anticipated threats. However, due to the small size of the facility, comprehensive
protection is often not feasible. In order to limit airborne contamination and maximize
the time for security personnel to shelter in place in order to initiate a response, utilize
protective gear, and respond to an attack, the design of the HVAC system should
include minimum measures such as those outlined in UFC 4-010-01. Design features
include elevated air intakes, emergency air distribution shutoff switch (or easily
accessible controls), and the use of gasketed doors and windows to minimize air
leakage.
6-9.6.6 Interior Lighting
The interior lighting should be diffused lighting and should be provided with dimmer
controls to aid with night vision and reduce the ability of those outside the guard facility
to see inside. The interior lighting should be connected to the backup power source.
As discussed in the IESNA HB-9, the illuminance inside the guard facility should be
limited to the minimum required for comfortable completion of the expected tasks and
functions. As indicated in Figure 29-17 of the IESNA HB-9, the recommended average
illuminance for the gatehouse is 30 footcandles (300 lx) on the work plane in the
gatehouse. Additional recommendations from the HB-9, include providing well-shielded
task luminaires to avoid reflections on monitors and windows. Also providing specular-
reflecting, low transmission glass at a tilted angle and painting the inside of the
gatehouse dark colors limit the view into the guard facility. Consider providing magenta
filters for interior lighting to lessen the impact of interior lighting on the night vision of
security personnel. See paragraph 6-14 for exterior lighting considerations

ELECTRICAL POWER REQUIREMENTS
Electrical design should consider current power demands as well as the communication
and power requirements for future traffic control devices, identification equipment, and
other devices associated with potential automation of the ECF. Coordinate power
requirements for vehicle barrier systems with the manufacturer. Barriers may require
three phase, 220-volt service.
