Class II Plants. Those employing a solvent having a flash point above one hundred degrees Fahrenheit (100° F.) (closed cup test) but not meeting requirements as further outlined herein for Class III or Class IV Plants.
3. 
Class III Plants. Those employing a solvent complying with the following specifications in dry-cleaning systems and drying cabinets or tumblers which have been specifically approved by Underwriters Laboratories, Inc., or a similarly recognized testing laboratory as being suitable for use with such solvents.

A. 
New Class I dry-cleaning plants or systems shall be prohibited.
B. 
Existing Class I dry-cleaning plants or systems may be continued in use, provided the quantity of cleaning solvent having a flash point below one hundred degrees Fahrenheit (100° F.) (closed cup test) that is stored or handled is not increased.
[R.O. 2013 § 520.050; Ord. No. KK64 Art. VIII, 3-7-1961]
A. 
Class II plants shall be located only in one-story, flat-roof buildings having masonry walls and with concrete or equivalent floors, above grade, and without pits, wells, pockets or basements. If located within the fire limits, roof shall be of fire-resistive construction; if located outside of the fire limits, roof may be of combustible construction provided that it is protected on the under side with a ceiling of cement or gypsum plaster on metal lath, or equivalent construction. Dry-cleaning or dyeing buildings shall not be closer than ten (10) feet to a property line, except that if the roof is of fire-resistive construction, standard masonry walls without openings may be located on the property line.
B. 
Dry-cleaning and dyeing operations shall not be carried on in the same building with other occupancies except that incidental operations such as laundering, pressing, ironing, etc., may be in the same building, or a communicating building, if separated from the dry-cleaning room or dyeing room by partitions or walls having a fire-resistance rating of not less that two (2) hours, with any communicating openings protected by standard fire doors approved for the protection of openings in such walls. There shall be at least two (2) means of exit provided from the dry-cleaning or dyeing room.
C. 
A mechanical system of ventilation shall be installed in dry-cleaning areas and dyeing rooms. Such system shall have sufficient capacity to insure complete and continuous change of air once every six (6) minutes, shall be provided with means for remote control, and shall operate automatically when any dry-cleaning equipment is in use.
[R.O. 2013 § 520.060; Ord. No. KK64 Art. VIII, 3-7-1961]
Class III plants may be located in buildings of any class of construction. If in the same building with other tenants, the dry-cleaning or dyeing section shall be cut off from the remainder of the building vertically and horizontally in an approved manner, including approved automatic or self-closing fire doors. Vertical cutoffs shall be not less than floor assemblies of double seven-eighths (7/8) inches wood flooring protected underneath by cement or gypsum plaster ceiling on metal lath; horizontal cutoffs shall be not less than cement or gypsum plaster on metal lath on both sides of wood studs. In no case shall Class III plants be located in a basement nor in a building also used as a place of public assembly.
