ยง 19.03. Construction  of booth; approval of plans and specifications.
  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:
1.  Dimensions.  Such booths shall be at least six feet in height.  If
  one machine is to be operated in such booth the floor space shall be not
  less than forty-eight square feet. If more than one  machine  is  to  be
  operated  therein,  an  additional  twenty-four  square  feet  shall  be
  provided for each such additional machine.
2. General specifications. In case such booth is  not  constructed  of
  concrete,  brick,  hollow tile or other approved fireproof material than
  asbestos, such booth shall be constructed with  an  angle  framework  of
  approved  fireproof  material,  the  angles  to be not less than one and
  one-quarter inches by three-sixteenths of an inch  thick,  the  adjacent
  members  being  joined  firmly  with  angle  plates  of metal. The angle
  members of the framework shall be spaced not more than four  feet  apart
  on  the  sides  and not more than three feet apart on the front and back
  and top of such booth. The sheets of asbestos board  or  other  approved
  fire-resisting  material  shall  be  at  least one-quarter of an inch in
  thickness and shall be securely attached to the framework  by  means  of
  metal  bolts  and  rivets.  The fire-resisting material shall completely
  cover the sides, top and all joints  of  such  booth.  The  floor  space
  occupied  by the booth shall be covered with fire-resisting material not
  less than three-eighths of an inch in  thickness.  The  booth  shall  be
  insulated  so  that it will not conduct electricity to any other portion
  of the building. There shall be provided for the booth a door  not  less
  than two feet wide and five feet ten inches high, consisting of an angle
  frame  of  approved  fireproof  material covered with sheets of approved
  fireproof material one-quarter of an inch thick,  and  attached  to  the
  framework  of  the booth by hinges, in such a manner that the door shall
  be kept closed at all times, when not used for ingress or egress.
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.
