tine, 1931] STORAGE AND HANDLING OF FILM 785 Laboratory film dryers of the drum type are being replaced by the generally less hazardous cabinet dryers. Such dryers should be heated by heaters that are thermostatically controlled to keep the temperature from reaching a dangerous degree. Heating elements should also be protected so that no film can come in contact with them. The care and handling of scrap film in laboratories, as well as in exchanges and elsewhere, is a matter of vital importance. The only safe place to keep scrap film is under water. Its form renders it very FIG. 6. Portion of positive assembly room in Hollywood laboratory after fire. Racks shown against wall contained 750 reels of film. Small racks each had capicity of 100 reels. This laboratory was not sprinklered. liable to ignition, and wax and other coatings on the film appear to make it more hazardous than new film. Room heating systems in laboratories, etc., may cause ignition of the film. Heating systems should be of the low-temperature type, steam or hot water. It is possible that even at the temperature of low-pressure steam heating radiators, film will become ignited upon long-continued contact. Hence all steam or hot water pipes and radiators must be protected by guards to keep film from touching them.
