(151) (Unchanged) The storage of motion picture film, not in process or being worked upon, and except as hereinafter specifically provided shall be in accordancewith the following rules:
(a) Except as provided in paragraph (6):
(1) Amounts in excess of 25 pounds (5 standard rolls but not in excess of 1000 pounds (200 standard rolls) shall be kept in approved cabinets if not in vaults;
(2) Amounts in excess of 1000 pounds shall be kept in vaults;
(3) Storage for any considerable length of time should be in vaults only.

C. regulation with each roll in a separate container, shall be kept in a sprinkler room, and if over 5 cases aggregating in excess of 750 pounds (150 standard rolls) shall be kept in a sprinklered room used for no other purpose.
Section 18— Handling of Film
(181) (Unchanged) Film shall be in containers. All film shall be kept in closed containers except during the actual time it is being worked upon or examined. This is very essential from the standpoint of fire hazard and safety to life. I. C. C. shipping containers and individual containers for each roll of film with proper corrugations on each side are recommended.
(182) (Unchanged) Film shall not be placed or kept under benches, tables, or other surfaces that would shield it from the discharge of sprinklers.
(183) (Unchanged) Scrap Film. — Scrap film shall be kept separate from waste paper and other rubbish, and shall be kept under water at all times. It shall be collected from work rooms at least once daily, and removed to a room used for no other purpose, where it shall be kept under water in steel drums with tight covers. These drums shall be disposed of at frequent intervals. Discarded film in full or part rolls shall be kept in vaults. Scrap film shall not be baled or burned.
Note. — Motion picture film in the form of clippings and short lengths is in a very hazardous form. Safe precautions in the handling of such scraps are most essential. Baling and burning of film are processes offering a distinct fire hazard. Sending film to a central reclaiming plant is recommended in lieu of burning.
