[1972 Code § 227.001]
To insure that all self-service or coin-operated dry cleaning establishments using solvents classified as nonflammable or as flammable at ordinary temperatures are maintained at safe and orderly places in which the public of this community may dry clean their clothing or other garments, and in order to prevent hazards that might otherwise be present in the public use of mechanically operated machines in such establishments, all self-service or coin-operated dry cleaning establishments are required to comply with the provisions of this chapter.
[1972 Code § 227.002]
No persons, firms, partnerships or corporations shall install or operate a coin-operated dry cleaning machine or machines, or make changes in any existing installations if such changes may affect health, until plans and specifications in duplicate shall first have been submitted to and received the approval of the Board of Health.
[1972 Code § 227.003]
Plans and requirements shall include:
Proposed arrangement including:
A diagram of that portion of the building in which the coin-operated dry cleaning machines are to be installed.
Location of the dry cleaning machines, the manufacturer and the model number.
Layout in plan and elevation views of the exhaust duct work. This shall be drawn to scale and shall show the ducts by double lines, supports, and the point of discharge out-of-doors.
Location and specifications of all general ventilating equipment including window or roof exhaust fans, supply fans and local exhaust fans. Fan specifications must include manufacturer, type, design, size, capacity, static pressure, speed and motor horsepower. Information substantiating compliance with the ventilation requirements must be included. The means by which the make-up air enters the building must also be shown.
The partitions which physically separate the customer area from the service area shall be so constructed as to allow the ventilation to flow from the customer area to the service area and then to the outside.
The curbed impervious floor in the service area shall be curbed to a height sufficient to retain the entire volume of solvent in the system, including auxiliary storage with the service area.
Solvent storage and control. Drains from the service area must be installed to drain the entire volume of solvent to a storage tank of proper size by gravity or by means of an automatic pump. This tank shall be vented to the out-of-doors. Solvent shall be stored only in closed containers which are properly labeled. The transfer of solvent from the containers should be accomplished in a line free of leaks. Filter residue and other residues and sludges shall be temporarily stored for safe disposal in tightly covered containers so as not to create a health hazard or nuisance.
A Bureau of Mines approved canister type gas mask with canister for the solvent used shall be provided. This gas mask shall be kept in good repair and available for immediate use with the canister seal removed. Canisters shall be replaced at the expiration of their shelf life or when the odor of the solvent can be detected through it. The attendant shall be trained in the use of this gas mask.
A solvent vapor sensing device within the tumbler is desirable to control the drying cycle and to prevent the removal of solvent laden garments. The machine design must be such that essentially no solvent is retained in the cleaned items upon completion of the dry cleaning cycle. A simple performance test is the lack of any solvent odor in a closed automobile containing a newly cleaned load.
A utility fire extinguisher of either the carbon dioxide or dry chemical type must be provided for use against electrical or oil fires.
Ventilation requirements are:
The working or maintenance portion of the machines shall not be readily accessible to the customers in the store.
As a means of minimizing any solvent vapor buildup in the customer area and in the service area resulting from any minor solvent leakage, it is required that there be a minimum flow rate of air away from the customer area, through the service area to the outside as follows:
Number of Machines
Minimum Flow Rate Per Machine
1 to 3
4 to 8
9 to 16
17 or more
The exhaust ventilation as described above shall be provided on a continuous basis while the store is open for business. The fan wiring shall be such that the dry cleaning equipment cannot be operated unless the fan system is in operation.
The cleaning equipment must be provided with an exhaust system capable of maintaining a minimum of 100 feet per minute face velocity through the loading door whenever the door is open. The ductwork connections from this system must be sealed (soldered or taped) and the discharge stack extended above the roof line.
A supply of tempered (heated to 60° to 65° F.) make-up air equal to or greater than the total volume of air exhausted from the plant shall be provided in order to eliminate any negative pressure conditions which might otherwise develop.
Exhaust ventilation stacks from dry cleaning machines shall not be located in proximity to combustion air intakes on gas-fired equipment or drier air intakes.
Machine exhaust vents shall terminate at least five feet above the building roof, shall not create a nuisance, and shall be located so as to prevent recirculations.
Air to replace the air exhausted shall be admitted to the building through openings designed for this purpose or through air supply systems.
Exhaust piping shall comply with the American Standards 29.2, currently approved by the American Standards Association "design and operation of local exhaust system."
It is important that solvent contaminated air even in very low concentrations (5-20 ppm) be kept out of the air intakes of all combustion equipment, so as to minimize the thermal decomposition of the solvent. Breakdown products such as hydrochloric acid, free chlorine and phosgene corrode metal surfaces, including flues and heater components, can seriously damage cloth through acid burns or weakening of fibers.
Where grille openings are to be installed in the partition to facilitate air movements, they shall be sized on the basis of at least 500 cfm per square foot of net grille area and shall be placed as close to the machines as possible. An example would be the use of a thirty-inch by six-inch grille located directly over a machine.
[1972 Code § 227.004]
A trained operator shall be in attendance at all times when the coin-operated dry cleaning establishment is open. The training of this attendant shall include knowledge of the safe operation of the machines installed and the handling of emergency situations. His telephone number shall be posted conspicuously for emergencies.
The machines shall be inspected daily and kept in good repair. All maintenance personnel shall be familiar with the necessary machine repairs and instructed as to proper methods of handling perchlorethylene. Access doors to the maintenance area shall be kept locked.
A step-by-step instruction list must be posted in a conspicuous location near the machine for customer use. Included shall be a list of items not to be dry cleaned.
Only the solvent and supplies specified by the equipment manufacturer shall be used. No spotting solvents other than water shall be permitted.
An interlock system must be provided on the machine to prevent the loading door from being opened during the normal cycle.
This system may be either electrical and/or mechanical and so connected that in the event of a power failure or other stoppage during the operating cycle the machine fails safe and the door remains locked and is not operable by a customer.
The drying time of the operating cycle shall be sufficient so that odor detectable concentrations of solvent vapors are not dispersed with the cleaned garments.
No open flames or surfaces heated to a temperature over 75° shall be allowed in the service area. Gas appliances may be used in the remainder of the building if they are vented to the outside by noncorrodible pipes.
