19.09 - Portable Booth for Temporary Exhibitions.

§ 19.09. Portable booth for temporary exhibitions. Where motion
pictures are exhibited daily for not more than one month, or not more
often than three times a week, in educational or religious institutions
or bona fide social, scientific, political or athletic clubs, a portable
booth may be substituted for the booth required in sections 19.01 and
19.03 of this article. Such booth shall have a height of not less than
six feet and an area of not less than twenty square feet and shall be
constructed of asbestos board, sheet steel of no less gauge than
twenty-four; or some other approved fireproof material. Such portable
booth shall conform to the specifications of section 19.03 of this
article with reference to windows and door, but not with reference to
vent flues. The floor of such booth shall be elevated above the
permanent support on which it is placed by a space of at least one-half
inch, sufficient to allow the passage of air between the floor of the
booth and the platform on which the booth rests, and the booth shall be
insulated so that it will not conduct electricity to any other portion
of the building.
