The equipment shall be installed such that only the front of the machine shall be exposed in the customer area. The working or maintenance portion of the equipment should be separated from the front of the machine by a solid partition. As a means of minimizing any solvent or vapor buildup in the customer area and also to control any minor solvent leakage, it is required that there be a minimum air flow rate from the customer area through the partition as follows:
No. of Machines
| Minimum Air Flow Rate Per Machine (cfm)1 |
1 - 3 | 500 |
4 - 8 | 400 |
9 - 16 | 375 |
17 or more | 360 |
1 Each cleaning cell shall constitute one machine.
The exhaust ventilation as described above shall be provided on a continuous basis while the establishment 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.
Where grille openings are to be installed in the partition to facilitate air movement, they should be sized on the basis of about five hundred (500) cfm per square foot of net grille area and should be placed as close to the machine as possible. An example would be the use of a thirty inch by six inch (30" x 6") grille located directly over a machine.
A supply of tempered make-up air shall be provided for the customer service area in an amount approximately equal to the exhaust ventilation required in the table on minimum air flow rate per machine in this Section. The device shall be capable of providing the above amount of make-up air at room design temperature with an outside air temperature equal to the mean winter temperature. In all cases it is required that the exhaust rate be slightly greater than the make-up rate which will at all times maintain a slight negative pressure in the customer service area.
Access doors to the maintenance area shall be kept locked.
Where there is no air flow through the partition between the customer and service area, the exhaust ventilation required in the table on minimum air flow rate per machine in this Section is sufficient provided that it is operated continuously with a satisfactory source of tempered make-up air in the service area. The volume of make-up air provided in the service area should be slightly less than the exhaust capacity in order that a slight negative pressure be maintained in the service area at all times. A supply of suitably tempered make-up air should be supplied for the customer area.
Auxiliary Fan -- Where there is air flow between the customer and the service area, it is also required that a general ventilation fan be installed in the back room or maintenance area to be used in case of serious solvent leakage. This fan may be installed in the rear wall and when combined with the system required in this Section should enable the exhausting of twice the amount of air required in the table on minimum air flow rate per machine in this Section.
Prevention of Leaks -- A satisfactory means of preventing liquid leaks from escaping the enclosure must be provided. The floor of the enclosure or machine base shall be diked so as to hold a liquid volume equal to the maximum quantity of solvent which might possibly escape from machines in the system. A method shall be provided for draining and containing solvent in the event of a leak. Tanks so provided for containing leaks shall be vented to the outside.
In lieu of the diking aforesaid, the integral pan and piping system may be used provided that the piping system is connected to a properly sized and vented holding tank as described above.
Use as Dwelling -- Equipment shall not be installed in a building occupied solely as a dwelling place.
Plans -- Any person establishing an automatic dry cleaning establishment shall be required to submit to the Director of Building and Zoning a complete set of plans and specifications of the building in which such dry cleaning establishment is to be located and also a complete diagram of the floor plan of each room to be occupied, correctly showing the area of all machinery and ventilating equipment to be installed therein.
A. Attendant: Automatic dry cleaning establishments may not be operated unless an attendant is on the premises at all times when such equipment is available for use by the public. Such attendant shall be trained and well qualified in the procedures relative to the safe operation of such equipment. The attendant as well as the owner shall be responsible for the enforcement of the provisions of this Article.
B. Instructions: In addition to the general machine operating instructions required by 8-16-3K there shall be posted a warning to the effect that garments or materials bearing the odor of the solvent are dangerous if enclosed in an automobile or other tightly enclosed place.
C. Warning Signs: Signs shall be posted requesting evacuation of the establishment in the presence of noticeable vapor odor or in the presence of such symptoms as irritation of the eyes, nose or throat, lacrimation or dizziness.
D. Age of Operator: No person under the age of sixteen (16) years shall be permitted to operate any automatic dry cleaning machine.
E. Hours of Operation: No automatic dry cleaning establishment shall be operated between the hours of ten o'clock (10:00) P.M. and seven o'clock (7:00) A.M.
A. Exhausts: Servicing of the machines shall be done only during operation of all exhaust ventilation functions required in Section 8-16-5 of this Article.
B. Storage: The solvent shall be stored in closed containers, and should be transferred from the containers in a line free of leaks. All storage facilities for solvent, external from the equipment, must be adequately and properly labeled.
C. Residues: Filter residue and other residues containing solvent shall be disposed of so as not to create a health hazard or nuisance. A covered metal container shall be used for temporary storage outside the building.
D. Protective Equipment: Respiratory protective equipment shall be provided for maintenance personnel and must be kept in good repair and available for immediate use. Chemical cartridge respirators are approved for light solvent concentrations and the wearer should replace the cartridges immediately upon noting odor.
Safety goggles, rubber gloves and rubber safety aprons shall be provided for the use of the service personnel.
