The ventilation system is designed to keep the humidity inside the file room below 50%.

3113. Basement file rooms are undesirable, not N/A N/A only because under certain conditions burn-ing or smoldering debris may be accumulated in a basement sufficient to produce a

" cooking effect" of such duration that it cannot be resisted by construction alone (within practical limitations), but also because basement rooms are apt to be damp, causing destruction of records by mold, and they are subject to flooding, under either flood or fire conditions, and consequent damage by water to some or all of the records.

3114. Exterior building walls forming part of a N/A N/A file room are subject to the penetration

~

of moisture, and condensation within the file room may result from differences be-tween the inside and outside temperatures.
