One of the chief characteristics of preventive conservation is that it constitutes a global, systematic and rational policy: there is no point in eradicating pests from objects if they are then stored in dirty and infested places, or handled carelessly.
One essential aspect is therefore the training and awareness-raising of museum staff... and of visitors, whose basic contribution to preventive conservation is not to touch the objects!
Every object and every type of collection requires a different preventive conservation programme, as each material has its own weaknesses and reacts differently to deterioration factors. However, preventive conservation attempts to reconcile these sometimes contradictory imperatives within a global project, adapted to the establishment in question. There are no ready-made solutions, and preventive conservation policy can vary enormously from one museum to another (just as storeroom conditions can vary).
Likewise, since a preventive conservation programme must be applied to the collection as a whole and developed within a specific environmental context, the strategic importance of the storeroom is obvious: it needs above all to be safe, clean, air-conditioned, and orderly. It is also a work place, where most preventive conservation actions (involving the objects themselves) are carried out.
