Anchors and Supports

DOE-STD-1088-95

5.3 Anchors and Supports

Each relocatable structure should have support and anchoring systems properly designed and

installed that will resist overturning and lateral movement of the structure.

5.4 Interior Finish

The interior finish of all relocatable structures should comply with NFPA 101, as amended below.

Relocatable structures used for any of the following occupancies should have an interior finish

with a flame spread rating <25 and a smoke development rating <50 per ASTM E84:

Dedicated to housing electronic data processing equipment or other computer equipment.

Structures used for sleeping quarters.

Structures used for storing, processing, or involving radiological materials.

Structures used for storing or operating lasers and related equipment.

The above delineated interior finish requirements should also apply to the shell covering material

of tension supported structures.

If fire retardant pressure impregnated wood is used as interior finish it should be the non-leachable

type that meets Underwriter's Laboratories (UL) "Standard Rain Test" and should be installed with

corrosion resistant fasteners that will withstand the chemicals impregnated in the wood. It should

be rated as FR-S material as currently listed in the (UL) Building Materials Directory or equivalent.

Fire retardant paint is not acceptable for flame spread reduction for interior finish.

5.5 Skirting

Relocatable structures with open under-floor areas should be provided with skirting to prevent the

accumulation of combustibles and debris beneath the structures.
