(a) Installation plans for self-service or coin-operated dry cleaning establishments shall be submitted to the Building Department at the time of making an application for the license required by this chapter and shall include information as to the number, make and model of the machines to be installed, the type of cleaning fluid to be used and the weight of clothing per load. All electrical equipment shall be installed in accordance with the requirements of the National Electrical Code for hazardous locations and special requirements of the local inspection authority.
(b) Coin-operated dry cleaning machines shall comply with the requirements set forth in this section. Satisfactory performance shall be verified by field tests. Manufacturers of dry cleaning machines shall provide the Building Department with detailed installation, operation and maintenance manuals. A complete description of the machine cycle, performance and location of all controls shall be included.
(c) The machine design shall be such that essentially no solvent is retained in the cleaned clothes upon completion of the dry cleaning cycle.
(d) a solvent vapor sensing device is desirable to control the drying cycle and to prevent the removal of solvent-laden garments.
(e) There shall be a lock on the machine to prevent the loading door from being opened during the complete cleaning cycle or in the event of a machine malfunction or power failure. This system may be either electrical or mechanical and so connected that the machine is fail-safe. The door lock shall be actuated by suitable safety controls to prevent the removal of solvent-laden clothing. Such controls shall sense malfunction of the solvent extraction, drying and deodorizing system resulting from:
(1) Improper drum rotation speed;
(2) Insufficient heat input;
(3) Inadequate airflow or circulation; or
(4) Unsatisfactory solvent condensation or recovery.
(f) The cleaning equipment shall be provided with an exhaust system to create a minimum of 100 feet per minute in-draft velocity through the loading door whenever the door is open. The ductwork connections from this system shall be sealed (soldered or taped) and the discharge stack extended to a minimum height of five feet above the roof of the building housing the cleaning equipment or above the roof line of any attached structure. Particular attention shall be given to discharge stack height and location where dwellings are located nearby.
(g) It is the responsibility of the proprietor to make certain that clothing which cannot be properly cleaned and dried will not be placed in the machines.
