Many nitrate films have been transferred in recent decades to safety stock, and original nitrate prints are generally stored separately to prevent a nitrate fire from destroying other non-nitrate films; the gas they release also affects the emulsion of safety film. Usually nitrate collections are even split up into several different fireproof rooms to minimize damage to an entire collection should a fire occur in one part.
In the context of film preservation, many nitrate films have been transferred to safety stock in recent years, and original nitrate prints are usually stored separately from other films to prevent a nitrate fire from causing damage. The gas released by such a fire can also affect safety film stocks, highlighting the need for specialized storage facilities.
