Vaults

 

Storage places for the long term archiving of films and videotapes.

Vaults are fireproof constructions fitted with temperature and humidification controls, or are so situated that these factors remain as constant as possible. For safety reasons, vaults are constructed so that each one contains no more than 1,000 to 2,000 cans of film or tape.

When nitrate film has to be stored for archival purposes, much more stringent precautions have to be taken than for modern safety base.
