Structural Fire Protection Criteria

DOE-STD-1066-99

8.3

Alarm System Extensions

Extensions to existing fire alarm systems and all new systems in existing buildings or facilities

should be compatible with existing fire alarm equipment at the location, including keys/locks,

similarity of alarm signals and equipment as well as user operated devices, training

requirements, and maintenance procedures.

9. STRUCTURAL FIRE PROTECTION CRITERIA

9.1

General

Any materials with unusual fire characteristics, such as urethane foams, and any materials

that develop significant quantities of toxic or harmful products of combustion (as delineated

in Material Safety Data Sheets and other sources of product information), should not be used

as interior finishes or other interior applications without the approval of the AHJ. The use of

foam plastics in construction should be prohibited unless it fully complies with Factory Mutual

(FM) Data Sheet 1-57.

9.2

Fire Barriers

9.2.1

Wall, floor and ceiling, and roof and ceiling assemblies should be tested and rated for

their fire resistance by Underwriter's Laboratories (UL) or similar nationally recognized

testing laboratories, or should be listed for their fire resistance as approved by FM or

similar organizations.

9.2.2

Fire Resistance - The development of an FHA and SAR should include consideration

of conditions that may exist during normal operations and special situations (e.g.,

during periods of decontamination, renovation, modification, repair, and

maintenance). Where required by the FHA or SAR, the structural shell surrounding

critical areas and their supporting members should remain standing and continue to

act as a confinement structure during anticipated fire conditions including failure of

any fire suppression system not designed as a safety class item. Fire resistance of

this shell should be attained by an integral part of the structure (concrete slabs, walls,

beams, and columns) and not by composite assembly (membrane fireproofing). In

no event should the fire resistance rating be less than 2 hours under conditions of

failure of any fire suppression system not designed as a safety class item. (Refer to

NFPA Standard 221 and FM Data Sheet 1-22.)

9.2.3

Special facilities should be designed and constructed using building components of

fire-resistant and noncombustible material, particularly in locations vital to the

functioning of confinement systems. Combustible materials should not be used in the

construction of process system confinement barriers.
