consistent with local national standards, and bilingual signs are permitted.
2-5.2.1
Radioluminous Exit Signs. Radioluminous exit signs in DOD
facilities are not permitted.
2-5.2.2
Photoluminescent Exit Signs. Photoluminescent exit signs and
egress path marking is permitted only where provided with a reliable external
illumination (charging) source providing a minimum illumination of 54 lux (5 foot-
candles) of unfiltered fluorescent light. External illumination source must be
energized at all times during building occupancy. Such lighting must not be
controlled by automatic timers, automatic sensors including area occupancy
sensors, or accessible manual switches. Controls for such lighting must be
accessible only to authorized personnel. Photoluminescent signs must only be
installed indoors and must not be exposed to direct sunlight, liquid spray, or
temperatures outside of the range of +10 to 40C (50 to 104F). The legible
viewing distance must be limited to 15.3 m (50 ft).

INTERIOR FINISH.
2-6.1
movable partitions must conform to the requirements of NFPA 101 for interior
2-6.1.1
Do not use drop-out ceilings (foam-grid panels).
2-6.2
Interior Floor Finish. Conform to the requirements of NFPA 101.
2-7
INSULATION.
2-7.1
Requirements. Use thermal and acoustical insulation with a flame
spread (FS) rating not higher than 75, and a smoke developed (SD) rating not
higher than 150 when tested in accordance with ASTM E84 (NFPA 255),
Standard Method of Test of Surface Burning Characteristics of Building
Materials. Test cellular plastic insulation in the same densities and thicknesses
as the material that will be used in construction applications.
2-7.2
Exceptions to Insulation Criteria. For certain types of insulation
installation, the exceptions described in paragraphs 2-7.2.1 and 2-7.2.2 apply.
2-7.2.1
Flame Spread - No Smoke Developed Rating Limitation.
Compliance with the SD rating limitation is not required, and a FS rating up to
100 is permitted for insulation, including insulating sheathing installed within wall
assemblies. In such installations, conform the interior finish materials to
paragraph 2-6 with a minimum fire-resistance rating of 15 minutes when tested in
