of dry cleaning or dry dyeing unless he/she shall first obtain from
the Building Inspector a permit setting forth the location, class
of plant, flash point of solvent and type of equipment to be used.
All provisions of this Chapter must be complied with and no change
shall be made in class of solvent nor in equipment unless permission

A.
For the purpose of this Chapter, dry cleaning and dry dyeing plants
shall be divided into the following four (4) classes.
1.
Class I plants shall be those employing as solvent having a
flash point below one hundred degrees Fahrenheit (100° F.) (closed
cup test).
2.
Class II plants shall be 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 shall be 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.
Flash point (closed cup test) is not lower than one hundred
thirty-eight and two-tenths degrees Fahrenheit (138.2° F.).
b.
Initial boiling point is not lower than three hundred fifty-seven
and eight-tenths degrees Fahrenheit (357.8° F.).
c.
Ignition temperature is not lower than four hundred fifty-three
and two-tenths degrees Fahrenheit (453.2° F.).
d.
The lower limit of explosive range is not less than eight-tenths
percent, (0.8%), by volume in air at an initial temperature of three
hundred two degrees Fahrenheit (302° F.).
e.
Solvents shall not heat spontaneously.
4.
Class IV plants shall be those employing a solvent classified
by Underwriters' Laboratories, Inc., or a similarly recognized testing
laboratory as nonflammable or as nonflammable at ordinary temperatures
and only moderately flammable at higher temperatures.
[Ord. No. 687 §804, 11-1-1960]
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.
[Ord. No. 687 §805, 11-1-1960]
A.
Class II plants shall be located only in one story, flat roof buildings
having masonry walls and with concrete or equivalent floor, above
grade, and without puts, wells, pockets, or basements. If located
within the fire limits, the roof shall be of fire resistant construction;
if located outside of the fire limits, the 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 drying 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 drying 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 drying room by partitions or walls having a fire resistance rating
of not less than 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 drying room.
C.
A mechanical system of ventilation shall be installed in dry cleaning
areas and drying 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.
[Ord. No. 687 §806, 11-1-1960]
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 drying 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-inch wood
flooring protected underneath by cement or gypsum plaster ceiling
on metal late; 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.
[Ord. No. 687 §807, 11-1-1960]
Class IV plants shall not be restricted as to type of building[1]

Editor's Note: So in original.
[Ord. No. 687 §808, 11-1-1960]
Heat for Class II plants shall be by steam or hot water only.
For Class III plants, heating shall be by any approved means which
does not involve any open flame or ignition source in the dry cleaning
area. Steam and hot water pipes and radiators shall be at least one
(1) inch from all woodwork and shall be protected by substantial metal
screens so as to prevent combustible goods or materials from coming
in contact with pipes or radiators.
[Ord. No. 687 §809, 11-1-1960]
Boilers for Class I and Class II plants shall not be located
in a dry cleaning or drying building. If located in a building adjoining
a dry cleaning or drying room, the boiler room shall be separated
from such room by a standard masonry fire wall without openings. Boilers
may be located in the same building with Class III plants, but if
adjoining dry cleaning areas they shall be cut off by a partition
of noncombustible material, without openings, having a fire resistance
rating of not less than two (2) hours.
[Ord. No. 687 §810, 11-1-1960]

steam smothering system or a carbon dioxide flooding system; also,
that washers and drying tumblers in Class I and Class II plants be
protected by a steam smothering system or a carbon dioxide flooding
system; also, that drying cabinets in Class III plants be protected
