GENERAL REQUIREELU TS -- Dry cleaning by immersion and agitation in open vessels is prohibited. - 4 - Dry cleaning by immersion and agitation in closed machines should be carried on with approved machinery and equipment installed and operated in accordance with the following standards. Before any dry cleaning; plant is established or before an existing plant is remodeled, complete drawings shall be submitted to the inspection department having jurisdiction for examination and approval. These drawings should be drawn to an indicated scale, give relative location of dry cleaning building, boiler room, finishing building or depart- ment, storage tanks for solvents, pumps, washers, drying tumblers, extractors, filter traps, stills, condensers, piping, etc., show sectional elevation of the buildings (including lowest floors or pits, tanks, their fittings, de- vices, etc. ). Specifications based on the following rules should accompany the drawings. As a means of determining the class of installation into which a dry cleaning system may fall, the following schedule developed by Underwriters ' Laboratories for the rating of hazards of flammable liquids shall be employed; Ether rates - - - - - - - - - - - 100 Gasoline rates - - - - - - - - - 90 - 100 Alcohol (ethyl) rates - - - - - 60 - 70 Kerosene rates - - - - - - - - - 30 - 40 Paraffin oil rates - - - - - - - 10 - 20 For the purpose of these standards, dry cleaning installations shall be arranged in four classes according to the foregoing hazard scale as follows: Class I - Systems utilizing solvents rated above 40 are prohibited. Class IT - Systems utilizing solvents rated 30 - 40 which do not comply with Class III or Class IV requirements. • Class III - Systems employing equipment approved by Underwriters ) Laboratories utilizing listed solvents having specified characteristics and rated at 25 or below. Class IV - Systems utilizing solvents classified as non- flammable, or as non-flammable at ordinary temperatures and only slightly flammable at higher temperatures (rated not over 5). (5). CLASS IT SYSMIS -- Systems utilizing solvents rated 40 or below but which do not comply with Class III or Class IV require- ments shall be designated as Class TI installations, and shall comply with the following requirements: NO`.I'E: Systems employing solvents rated 25 or below, but not provided with approved equipment as required under Class III, or where such solvents are not listed specifically for use with such systems, shall auto- matically fall in Class II. (6). LOCATION -- The requirements of this section are based upon locations in unsprinklered buildings; at the discretion of the inspection department having jurisdiction they may be modified if the building is protected throughout by means of an approved automatic sprinkler system. Dry cleaning plants should preferably be located in outlying sparsely guilt sections, but when located in congested districts shall be not closer than ten feet to the line of adjoining property, unlessthe exposing; wall of the plant is of blank masonry construction.

NOTE: The requirements of the above paragraph may be waived at the discretion of the inspection department having jurisdiction based upon a consideration of such factors as type of building construction involved, nature of operations, and extent of private protection provided. Drying should preferably be conducted in suitably protected drying cabinets or tumblers, but where done in dry rooms, such rooms shall be con- structed with walls, partitions and ceilings of material capable of furnishing one hourts resistance to fire, and having self-closing doors of equivalent construction.

Systems employing solvents rated at 25 or below, but not provided with approved equipment as required under Class III, or where such solvents are not listed specifically for use • with such systems, shall automatically fall in Class II. (15). LOCATTON, GENERAL REQUIREMENTS, EQUIP!-1ERT, ETC. -- The regulations of the National Fire Code 's Volume I, 1951, for flammable liquids, chemical and gas explosives shall apply to all Class III dry cleaning systems regarding location, equipment, methods, operations, and general re- quirements and reference shall be made thereto. (16) CLASS IV -- Systems utilizing solvents classified as non-flammable or as non-flammable at ordinary temperatures and only slightly flammable at higher temperatures (rated not over 5) shall be designated as Class IV installations, and shall comply with the following requirements: Owing to the slight fire hazard inherent to dry cleaning systems of this class, installation and operating requirements are mainly unnecessary. It should be borne in mind, however, that this freedom from restriction and regulation is conditioned on the operation of such systems with solvents of the rating for which they are designed. When such conditions are violated, the system must be classed in accordance with the rating of the most hazardous solvent used, and the installation and operating re- quirements related thereto strictly complied with. Systems of this type should be so designed, installed and operated, that the casualty hazards incident to electrical features • and nature of solvents employed are safeguarded to a reasonable and acceptable degree. Such systems should not be installed in basements or other locations difficult to ventilate. Adequate ventilation is of urgent importance because of the toxic nature of the solvent vapors involved. The use of any flammable solvent for brushing, scouring or scrubbing shall be prohibited. The use of such liquids for spotting purposes shall be limited to one quart with storage in and application from an approved safety can. The provision of one or more fire extinguishers is recom- mended. SECTION 22. That by the term "person" as used herein shall mean any person or corporation or co-partnership or association or persons or their agents, servants or employees. SECTION 23. That if after the issuance of any permit to any person as provided herein such person may by sale or otherwise transfer the said business to any other person then it shall be the duty of the said person to whom the said permit was issued to furnish the name of the new person to whom the business is sold and a record shall be kept thereof in the Blilding Inspect- or Is Department. SECTION 24. That if for any reason any section or provision of this ordinance shall be held to be invalid the same shall not be construed to affect any other provision hereof. SECTION 25. PENALTY -- That any person violating any of the pro- visions of this ordinance shall be subject to a fine upon conviction in the Corporation Court in any sum not exceeding Two Hundred ($200.00) Dollars, and each and every act shall constitute a distinct offense; and violations of the terms of this ordinance shall be subject to the same fine for each and every day the same is kept in violation of the terms hereof. -- 13 - - a ;SECTION 26.
