Discs should be labelled on their protective packaging rather than directly on the discs themselves. Inks from pens and markers may contain solvents that can damage the disc and graphite dust from pencils may interfere with reading of the disc. 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.
