Safe Handling, Storage, and Destruction of
Photographic films on cellulose nitrate base (nitrocellulose) were introduced by Eastman Kodak Company in 1889. This film base had excellent physical properties, but it suffered from poor chemical stability and high flammability. In 1948, cellulose triacetate support was introduced; it met the performance requirements of motion picture films and provided added safety. After 1951, no cellulose nitrate motion picture film was manufactured by Kodak.
Actual use of cellulose nitrate films in theaters has virtually ceased. However, large quantities of cellulose nitrate film for archival or other purposes still exist in storage. These films are typically kept in vaults and removed for limited projection, reprinting and restoration on safety films, or destruction.
This publication will help you recognize and avoid the hazards associated with cellulose nitrate motion picture films. To safely handle, store, transport, and destroy these films, you must understand these hazards. The information in this publication is based on requirements in the United States; requirements may differ in other countries.
The storage and handling requirements presented are primarily from the National Fire Protection
Association (NFPA), Standard for the Storage and Handling of Cellulose Nitrate Motion Picture Film, 1994 Edition (NFPA 40). The NFPA standards are not laws; however, states or local authorities, such as a government agency, local fire department, or a building/ electrical inspector may require compliance with the NFPA standard.
IDENTIFICATION
Depending on the age of cellulose nitrate films, the edge of the film may be marked as nitrate film (“NITRATE FILM” or “ N ”).
The words “SAFETY FILM” may appear in the
