Safe Handling, Storage, and Destruction of Nitrate-Based Motion Picture Films

H-182 (ENG) $1.00

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 non-image area of a motion picture film. This usually indicates that the base is made of a material, such as cellulose triacetate, that passes the ISO 435 test for burning and ignition. However, early motion picture films marked “SAFETY FILM” may have been printed on cellulose nitrate film, which would also carry the “SAFETY FILM” markings from print through. If a film cannot be clearly identified by markings, testing may be required to determine the composition of the film base.

This publication will help you understand the requirements to safely handle, store, transport, and destroy cellulose nitrate-based films.
