NFPA NFPA 40 Handbook 2022 Free Download: Storage and Handling of Cellulose Nitrate Film

NFPA 40 is a comprehensive standard that provides guidance on the safe storage and handling of cellulose nitrate-based film, which was widely used in cinema until the early 1950s. Despite its obsolescence, the material is highly flammable and poses significant safety risks, making the standard relevant for archival collections. The standard covers various aspects including: - Construction Requirements and Arrangements of Buildings: It details the construction of buildings, exits, explosion venting, space for workers, tables and racks, electrical equipment, heating, cooling, and refrigeration equipment, and duct systems. - Fire Protection: It provides guidelines for automatic sprinklers, water supplies, and portable fire extinguishers. - Storage of Nitrate Film: It outlines the general rules for film cabinets, vaults, extended term storage cabinets and vaults. The 2019 edition of NFPA 40 includes new definitions reflecting modern archivist terminology, updated requirements for extended term storage vaults, revised requirements for projection booths, and added requirements for temperature and humidity control. The standard continues to evolve to ensure safety around flammable film.
