Enclosures and shelving
The packing and storage of archives should ensure sufficient air movement to avoid pockets of stagnant air and to remove off-gassing from deterioration of materials. Shelving should be strong and adequately braced. The archival records should be stored on the shelving in archival boxes made of acid-free archival quality materials. Tailor-made enclosures and separate protection should be given to volumes, oversize documents and maps. PD 5454: 2012 provides specific guidance on packaging and storage.
