Make sure the box is not too big or too small, and the box is not full or too empty, as easy retrieval means less handling. Boxes should not be stacked more than four high and should be stacked like brickwork to avoid caving in boxes on the bottom row. In these conditions the natural deterioration of the items can be slowed. In some instances deterioration can be slowed further by lower temperatures. It is important that these environmental levels are stable.
Materials degrade quicker when exposed to ultraviolet light.
Fluorescent tubes which are low in ultraviolet light should be used wherever possible in storage areas. Lights should be turned off whenever possible. Storage areas should not have windows, but if they do they should be covered with curtains or blinds. Insect pest strips can be used as localised insect deterrents. However, the strips should not come into direct contact with individual items.
