(a) Fire hazard. No operation shall involve the use of highly flammable gases, acids, liquids, grinding processors or other inherent fire hazards. This provision shall not be construed to prohibit the use of normal heating fuels, motor fuels and welding gases when handled in accordance with other ordinances of the city.
(b) Noise.

(c) Sewage and liquefied wastes. No operation shall be carried on which involves the discharge into the sewer, watercourse or liquid wastes of chemical nature which are detrimental to normal sewage plant operations or corrosive and damaging to sewer pipes and installations.
(d) Air contaminates or pollutants.
1. Air contaminates and smoke shall be less dark than designated Number One on the Ringleman Chart as published by the United States Bureau of Mines, except that smoke of a density designated as Number One shall be permitted for one four-minute period in each one-half hour. Light colored contaminates of such an opacity as to obscure an observer’s view to a degree equal to or greater than the aforesaid shall not be permitted.
2. Particulate matter or dust as measured at the point of emission by any generally accepted method shall not be emitted in excess of two-tenths grains per cubic foot as corrected to a temperature of 500°F, except for a period of four minutes in any one-half hour, at which time it may equal but not exceed six-tenths grains per cubic foot as corrected to a temperature of 500°F.
3. Due to the fact that the possibilities of air contamination cannot reasonably be comprehensively covered in this section there shall be applied the general rule that there shall not be discharged from any sources whatsoever such quantities of air contaminates as constitute a detriment, nuisance or annoyance to any considerable number of persons or to the public in general or endanger the comfort, repose, health or safety of any such considerable number of persons or have a natural tendency to cause injury or damage to business, vegetation or property.
(e) Odor. The emission of odors that are generally agreed to be obnoxious to any considerable number of persons, shall be prohibited. Observations of odor shall be made at the property line of the establishment causing the odor. As a guide to classification of odor, it shall be deemed that strong odors of putrefaction and fermentation tend to be obnoxious and that such odors as associated with baking or the roasting of nuts and coffee shall not normally be considered obnoxious within the meaning of this ordinance.
(f) Gases. The gases sulphur dioxide and hydrogen sulphide shall not exceed five parts per million, carbon monoxide shall not exceed 25 parts per million and nitrous fumes shall not exceed five parts per million. All measurements shall be taken at the property line.
(g) Vibration. All machines including punch presses and stamping machines shall be so mounted as to minimize vibration and in no case shall such vibration exceed a displacement of three-thousands of a inch measured at the property line. The use of steam or broad hammers shall not be permitted.
(h) Glare and heat. All glare, such as welding arcs and open furnaces shall be shielded so that they shall not be visible from the property line. No heat from the furnaces or processing equipment shall be sensed at the tot line to the extent of raising the temperature of air or materials more than 5°F.
(11) Fence regulations. All fences, walls and hedges shall be in conformance with the regulations provided herein and with the provisions of § 11-515.
