Sept., 1930] STORAGE OF MOTION PICTURE FILM 291 earthquakes, vandalism, or destruction in time of war, but in this respect protection can be insured by making duplicate copies and storing these in places widely separated geographically. STORAGE DEVICES INVESTIGATED (1) The approved type of storage vault for motion picture positive film consists of a fireproof room with open racks for supporting the rolls of film which stand on edge in separate cans, each containing 1000 feet of film.3 Ample sprinkler equipment precludes the burning of large quantities of film or the explosion of decomposition fumes, FIG. 1. Plain wood experimental cabinet (front view). but if one roll becomes ignited, a number of others near it usually are decomposed or burned. Also in the event of fire a large quantity of film is apt to be damaged by water. These conditions make this type of storage vault undesirable for valuable film. (2) Steel lockers with sprinkler heads fitted at the top are likewise unsatisfactory because the surroundings are imperfectly protected. (3) Cabinets are available on the market in which the rolls of film are contained in separate vented compartments insulated from each other and from the outside. These cabinets afford satisfactory protection but the film rolls are stored on edge.
