No person, firm or corporation owning or operating a dry cleaning business or laundry business, and no person having charge of the operation of such business, shall operate or permit the operation of such business except in compliance with the following requirements:
(a) No coin-operated dry cleaning machine or coin-operated laundry machine shall at any time be accessible to use by any person who is not the owner, operator or employee of such dry cleaning business or laundry business in which such machine is situated unless an owner, operator or employee of such business is present and is available to directly supervise the use of machines accessible to public use and is directly supervising the use of such machine in use.
(b) All coin-operated-dry cleaning machines and coin-operated laundry machines shall be fitted with a device which prevents the opening of the door of any such machine while such machine is in operation. A coin-operated dry cleaning machine shall be so constructed that a failure or malfunction of such machine shall cause it to stop in a safe position and only machines approved by the National Board of Fire Underwriters shall be permitted.
(c) In the event that perchlorethylene or any chlorinated hydrocarbon or any other chemical or solvent is a component part of any solvent used in a coin-operated dry cleaning machine, then such dry cleaning machine may not be used if the odor of perchlorethylene or any chlorinated hydrocarbon or any other chemical or solvent vapor of such perchlorethylene 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) 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. The gutters shall be so arranged as to cause solvent to drain into such tank by means of gravity flow.
(e) 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) 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) All sludge removed from dry cleaning filters must be placed and stored in tightly covered containers.
(h) Rooms in which coin-operated dry cleaning machines are installed shall be equipped with ventilating systems capable of changing the air in the room once every three minutes. This ventilating 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) 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.
