Conserve-O-Gram 2/22 Disposal of Cellulose Nitrate Film
Source: National Park Service (NPS)
Cellulose nitrate (“nitrate”) film was manufactured from about 1910-1950 for use as a non-breakable, lightweight alternative to glass plate photographic negatives. It was also used as a motion picture film medium. Unfortunately, nitrate film is a severe fire safety hazard. Once burning, a nitrate film fire is
very difficult to extinguish. Such fires release numerous toxic gases. Even when not on fire, deteriorating nitrate film is hazardous. As it breaks down, nitrate releases noxious gases that can be dangerous to both people and other collections.
