As used in this article, the following terms
shall have the meanings indicated:
The process of removing dirt, grease, paints and other foreign
matter from wearing apparel, textiles, fabrics, rugs and similar materials
by the use of nonaqueous liquid solvents. Wherever reference is made
to "dry cleaning," same shall be construed as applying to both dry-cleaning
and dry-dyeing operations.
The process of dyeing clothes, other fabrics or textiles
in a solution of dye colors and flammable liquids.
For the purposes of this article, dry-cleaning
installations shall be classified as follows:
A.
Class I. Class I installations shall be those utilizing
a solvent having a flash point below 100° F., closed cup tester.
B.
Class II. Class II installations shall be those utilizing
a solvent having a flash point between 100° and 138° F., closed
cup tester.
C.
Class III. Class III installations shall be those
utilizing a solvent having a flash point of 138° F. or higher,
closed cup tester, provided that an installation utilizing such a
solvent with equipment other than equipment which, according to accepted
good practice, is designed and adapted for use with such solvents,
shall be regarded as a Class II installation for the purpose of this
article.
D.
Class IV. Class IV installations shall be those utilizing
solvents classified as nonflammable or as nonflammable at ordinary
temperatures and only slightly flammable at high temperatures.
No person shall engage in the business of dry
cleaning or dry dyeing until he shall have reported to the Fire Chief
the location, class of installation, flash point of solvent and type
of equipment to be used, nor shall he change the class of solvent
or equipment without reporting the same.
No solvent shall be used in any equipment other
than the class of solvent for which such equipment was designed.
Class I installations shall be located only
in one-story, flat-roofed, noncombustible-type buildings, without
attic or concealed roof space, having window openings in at least
two sides and with concrete or equivalent floors above grade and without
pits, wells, pockets or basement. Buildings with brick walls not less
than 12 inches thick or equivalent construction and without openings
may be located on property lines; otherwise buildings shall not be
closer than 10 feet to a property line. Wired glass, metal frame skylights
and wired glass, metal frame windows shall be provided, with all sashes
arranged to swing outward in case of an explosion. Any drying room,
if under the same roof, shall be separated from any dry-cleaning room
by partitions having a fire-resistance rating of not less than two
hours. Entrances to any drying room shall be protected by self-closing
fire doors. There shall be at least two doors leading outside the
building from any room used for dry-cleaning purposes. Doors shall
swing in the direction of exit travel. Buildings employing Class I
installations shall not be used for any other purpose.
Class II installations shall be located in buildings
having walls of masonry or noncombustible construction. The wall finish
shall be plain or plastered without furring or concealed spaces. Floors
shall be of fire-resistant construction, without pits, wells or pockets;
and where located over a basement, the floor shall be vapor- and liquidtight.
Roofs and floors above grade floor, if of combustible construction,
shall have the ceilings over the dry-cleaning areas protected by cement
or gypsum plaster on metal lath or equivalent construction having
a one-hour fire-resistance rating. Buildings used for dry-cleaning
purposes shall not be closer than 10 feet to the line of adjoining
property, except that if exterior walls are without openings, the
building may be located on the property line. Dry-cleaning operations
shall not be located on any floor below grade nor in the same building
with other occupancies. Operations incidental to the business, such
as laundering, pressing, ironing and kindred operations, may be in
an adjoining and connected building or located on the same floor with
the dry-cleaning plant, provided the dry-cleaning operations are separated
therefrom by fire partitions capable of providing one hour's resistance
to fire and the communicating openings are protected by fire doors.
Class III installations may be located in buildings;
of any class of construction, but in no case shall they be located
in a basement or in a building also used as a place of assembly or
public assembly. If located in the same building with other occupancies,
such operations shall be cut off from the remainder of the building
vertically and horizontally by construction providing one hour's resistance
to fire. All openings in interior fire partitions shall be protected
by fire doors.
Class IV installations shall be excepted from
the provisions of this article.
Boilers for plants employing Class I, Class
II or Class III installations shall be located in a detached building
or in a boiler room cut off from the dry-cleaning room by a partition
having a fire-resistance rating of not less than two hours, with openings
protected by self-closing fire doors and having sills raised at least
six inches above the dry-cleaning room floor, provided that where
a Class I installation is used, such a separating partition shall
be an unpierced brick wall at least 12 inches thick or equivalent
construction.
A mechanical system of ventilation shall be
provided in the dry-cleaning rooms of plants employing Class I or
Class II installations; such system shall be of sufficient capacity
to ensure complete and continuous change of air once every three minutes
for Class I installations and once every six minutes for Class II
installations and shall be provided with means of remote control.
For Class III installations, satisfactory ventilation shall consist
of fans, pipes and ducts properly arranged to vent the drying tumblers
and drying cabinets to the outside air.
Aboveground containers comprising purifiers,
clarifiers, filter and other reclaiming equipment in Class I and Class
II installations shall not exceed 350 gallons' individual capacity.
Solvent storage tanks for Class I installations shall be underground
and installed in accordance with this article. Solvent storage tanks
for Class II and Class III installations may be aboveground if the
individual capacity of tanks does not exceed 275 gallons and the aggregate
capacity of storage tanks does not exceed 550 gallons. Quantities
of solvents for Class II and Class III installations in excess of
the above shall be in buried tanks. The handling of solvents from
storage tanks through the various machines and back to the settling
and clear solvent tanks shall be through a closed circuit of piping.
The cylinders and shells of all washing machines,
drying tumblers, walls of drying cabinets, outside shells of extractors
and all aboveground containers shall be permanently and effectively
grounded.
A.
Class I. Where Class I installations are used, all
electrical equipment in dry-cleaning rooms or other sections subject
to vapors shall conform to generally accepted good practice for similar
hazardous locations, and compliance with the requirements of the electrical
standards of the Village for Class I, Group D hazardous locations
shall be deemed to be conformance with generally accepted good practice.[1]
B.
Class II. Where Class II installations are used, all
electrical equipment within eight feet of the floor in dry-cleaning
rooms or other sections subject to flammable vapors shall conform
to generally accepted good practice for similar hazardous locations,
