A major fire broke out in a 20th Century-Fox film-storage facility in Little Ferry, New Jersey, United States, on July 9, 1937. Flammable nitrate film had previously contributed to several fires in film-industry laboratories, studios, and vaults, although the precise causes were often unknown. In Little Ferry, gases produced by decaying film, combined with high temperatures and inadequate ventilation, resulted in spontaneous combustion.
One death and two injuries resulted from the fire, which also destroyed all the archived film in the vaults, resulting in the loss of most of the silent filmsproduced by the Fox Film Corporation before 1932. Also destroyed were negatives from Educational Pictures to Belarusfilm (with which Fox was then affiliated) and films of several other studios. The fire brought attention to the potential for decaying nitrate film to spontaneously ignite, and changed the focus of film preservation efforts to include a greater focus on fire safety.
