NFPA 40 provides guidelines for the storage and handling of cellulose nitrate motion picture film. Coverage includes information on film cabinets, vaults, archival vaults, projection rooms, and film exchanges. The 2001 Code has been expanded to include requirements for flat (still) cellulose nitrate film as well as motion picture cellulose nitrate film. This expanded coverage consolidates all cellulose nitrate film storage requirements into one document.
