Penetrations

DOE-STD-1066-99

9.3

Flame Spread

9.3.1

Exposed interior wall or ceilings (including ceilings formed by the underside of roofs),

and any factory-installed facing material, should have a UL-listed/FM-approved flame

spread rating of 25 or less and a smoke developed rating of 50 or less, per ASTM

E-84.

9.3.2

Ductwork constructed of Fiberglass Reinforced Plastics (FRP) should be listed or

approved for use without interior sprinklers, or should be provided with automatic

sprinklers per the applicable FM Data Sheets.

9.4

Roofing Systems

9.4.1

Membrane roof systems should be constructed in accordance with the FM Loss

Prevention Data Sheets.

9.4.2

Built-up bituminous membrane roofing on metal decks should comply with FM Class I.

9.5

Penetrations

9.5.1

Fire Barrier Penetration Seals - Fire barrier penetration seals should comply with

NFPA 101, Chapter 6. Penetration seal materials and assemblies should be tested

for their fire resistance and listed by UL or similar nationally recognized testing

laboratories, or should be approved by FM. Where fire-rated assemblies (walls,

floor-ceilings, roof-ceilings) are either partially or fully penetrated by pipes, ducts,

conduits, raceways or other such building elements, fire barrier penetration material

should be placed in and around the penetrations to maintain the fire resistance rating

of the assembly.

9.5.2

Where fire barriers are penetrated by the confinement system's ventilation ducting,

fire dampers should be appropriately used to maintain the barrier integrity. However,

the closure of such dampers should not compromise the functions of the confinement

system where the loss of confinement might pose a greater threat than the spread of

fire. In such cases, alternative fire protection means (e.g., duct wrapping, duct

enclosure or rerouting) should be used as a substitute for fire barrier closure.

Sprinkler systems, such as those designed as a "water curtain," should not be

considered a fire barrier substitute.

9.6

Carpets and Rugs

9.6.1

Carpets and rugs should be tested in accordance with NFPA 253

(ASTM E-648) when applying the floor finish requirements of the Life Safety Code

(NFPA 101) to DOE facilities.

9.6.2

Carpets and rugs used in storage or industrial occupancies (no criteria in NFPA 101)

should have a critical radiant flux not less than the following:

o 0.45 watts per square centimeter in areas unprotected by an automatic fire

suppression system; and
