The booths provided for in section 19.01 of this article shall be constructed according to plans and specifications which shall have been first approved, in a city, by the mayor or chief executive officer of the city department having supervision of the erection of buildings in such city; in a village, by the mayor of such village; in a town outside the boundaries of a city or village, by the supervisor of such town. Provided, however, that no plans and specifications for the construction of such booths shall be approved by any public official, unless the following requirements are substantially provided for in such plans and specifications:
The operating windows, one for each machine to be operated therein and one for the operator thereof, shall be no larger than reasonably necessary, to secure the desired service, and shutters of approved fireproof material shall be provided for each window. When the windows are open, the shutters shall be so suspended and arranged that they will automatically close the window openings, upon the operating of some suitable fusible or mechanical releasing device.
Where a booth is so built that it may be constructed to open directly on the outside of the building through a window, such window shall be permitted for the comfort of the operator, but such booth shall not be exempted from the requirement of the installation of a vent flue as hereinafter prescribed. Said booth shall contain an approved fireproof box for the storage of films not on the projecting machine. Films shall not be stored in any other place on the premises; they shall be rewound and repaired either in the booth or in some other fireproof inclosure. The booth in which the picture machine is operated shall be provided with an opening or vent flue in its roof or upper part of its side wall leading to the outdoor air. The vent flue shall have a minimum cross-sectional area of fifty square inches and shall be fireproof. When the booth is in use there shall be a constant current of air passing outward through said opening or vent flue at the rate of not less than thirty cubic feet per minute.
