Translations:Addendum II/23/en

If the space permits, one or more fans can ensure adequate ventilation. However, the use of fans should be avoided if the documents contain spores or fungi, in which case the moving air could spread the spores around the space and thereby harm staff, the integrity of the documents, or both. If an air conditioner is used, it must have a mechanical filter that can be changed frequently. Finally, the consumption of food and drink in the workspace should be prohibited to prevent damage to documents during handling. In addition, food and drink remnants can attract insects that might further damage and degrade the documents.
