4.2 Storage area location

Ideally, a storage area should be in the centre of a building, slightly elevated from the ground floor. Such a location would permit effective and autonomous control over all environmental factors, including temperature, humidity and water, dust and pollution, light, as well as stray magnetic fields. Any location at the fringe of a building would make such control more difficult, and possibly less effective. Any location lower than ground level makes air conditioning more expensive, and effective prevention of water influx difficult. Vaults should be fireproof, thermally insulated, and also protected against water influx, which may happen for a number of reasons.
