717.02 REQUIREMENTS.
   A coin-operated dry cleaning establishment shall comply with the following requirements:
   (a)   Supervision by Attendant. No coin-operated machine shall be used by the general public unless under the direct supervision of an employee of a coin-operated dry cleaning establishment or a person owning and operating such establishment.
   (b)   Machine Doors and Approval. All coin-operated dry cleaning machines shall be fitted with a device which would prevent the opening of the door of any such machine while such machine is in operation. The machine shall be so constructed that a failure or malfunction of such machine shall cause it to stop in a safe position. Only machines approved by the American Insurance Association shall be permitted.
   (c)   Solvent Vapor and Odor. In the event that perchloroethylene or any chlorinated hydrocarbon or any other chemical or solvent is used in a coin-operated dry cleaning machine, such dry cleaning machine may not be used if the odor of percloroethylene or any chlorinated hydrocarbon or any other chemical or solvent is masked or altered in any fashion, and if the concentration of solvent vapor of such perchloroethylene or chlorinated hydrocarbon or any other chemical or solvent is greater than seventy-five percent of the Threshold Limit Values as established and periodically revised by the American Conference of Governmental Industrial Hygienists at any time and anywhere in the establishment in which such coin-operated dry cleaning machines are in use.
   (d)   Gutters for Solvent Flow. No coin-operated dry cleaning machine may be used unless directly in front of and behind any such machine there are gutters leading to a buried drain tank of sufficient size to accept all solvent contained in all coin-operated dry cleaning machines in the establishment. Such gutters shall be so arranged as to cause solvent to drain into such tank by means of gravity flow.
   (e)   Installation Near Gas-Fired Devices. No coin-operated dry cleaning machine may be located within twenty-five feet of any gas-fired dryer or similar gas-fired device, unless the installation is such that the positive flow of air is away from the gas-fired device or if the flame in such a device is totally isolated from the atmosphere in the establishment and the combustion air and make-up air are brought directly to the gas-fired device from the outside.
   (f)   Sources of Danger. In any coin-operated dry cleaning establishment, solvent storage tanks, power boxes and other sources of danger shall be so situated as to be inaccessible to the general public.
   (g)   Sludge Storage. All sludge removed from dry cleaning filters must be placed and stored in tightly covered containers.
   (h)   Ventilating Systems. Rooms in which coin-operated dry cleaning machines are installed shall be equipped with ventilating systems capable of changing the air in such room once every three minutes. This ventilation system shall be so wired that the dry cleaning machines cannot be operated if the ventilating system is not in operation. Such ventilating system shall exhaust to the outside atmosphere and such exhaust outlet shall not be closer than twenty-five feet to any opening in any building or within 100 feet of a residential area unless the vapor concentration at the exhaust outlet does not exceed twenty percent of Threshold Limit Value as established by the American Conference of Governmental Industrial Hygienists.
   (i)   Posting Danger Signs. All coin-operated dry cleaning establishments shall prominently display lighted indoor signs warning the general public of the danger of excessive solvent vapor inhalation and skin irritation from unevaporated dry cleaning solvent.
   (j)   Waiver. The requirements of subsection (d) and (e) hereof may be waived by the Fire Chief if the enforcement of these requirements would force major remodeling or rebuilding of existing facilities.
