Section 35.72. Construction

(a) New structures. Booths and room booths shall be constructed of noncombustible material. If the booths contain windows or glass panels, wire glass shall be used if the face area of the booth is more than 4 square feet. Unless the floor outside the booth is constructed of noncombustible materials, such floor shall be protected with nonsparking metal for a distance of 2 feet from the face of the booth, except in the case of small booths having bottoms 2 feet or more above the building floor. Floors in front of booths shall be so constructed and maintained that they are not a slipping hazard.

(b) Wooden structures. All existing wooden booths, with the exception of those having a working face area of 4 square feet or less, shall be replaced by booths constructed in accordance with subsection (a); unless, in the judgment of the Department, the hazard warrants the immediate discontinuance of such booths, or when they have been satisfactorily lined with noncombustible material.
