All activities involving, and all storage of, inflammable and explosive materials shall be provided with adequate safety devices against the hazard of fire and explosion and with adequate fire-fighting and fire-suppression equipment and devices standard in industry and as approved by the Fire Department. All incineration shall be prohibited.

Any device which radiates radio frequency energy shall be so operated as not to cause interference with any activity carried on beyond the boundary line of the property upon which the device is located. No radiation of any kind shall be emitted which is dangerous to human beings.

No emission shall be permitted at any point from any chimney or otherwise of visible gray smoke of a shade equal to or darker than No. 2 on the Power's Micro-Ringlemann Chart, copyrighted 1954, published by the McGraw-Hill Publishing Co., Inc. (being a direct facsimile reduction of a Standard Ringlemann Chart as issued by the United States Bureau of Mines), except that visible gray smoke of a shade equal to No. 3 on said chart may be emitted for four minutes in any 30 minute period.

No emission shall be permitted of odorous gases or other odorous matter in such quantities as to be readily detectable when diluted in the ratio of one volume of odorous air to four volumes of clean air at the lot line. Any process which may involve the creation or emission of any odors shall be provided with a secondary safeguard system so that control will be maintained if the primary safeguard system should fail. Table III, "Odor Thresholds," of Chapter 5, "Air Pollution Abatement Manual," copyrighted 1951, published by the Manufacturing Chemists' Association, Inc., Washington, D.C., is hereby established as a guide for determining quantities of offensive odors.

No emission shall be permitted which can cause any damage to health, animals, vegetation, or other forms of property or which can cause any excessive soiling at any point. No emission shall be permitted in excess of the standards set forth in Table I of Chapter 5, "Industrial Hygiene Standards, Maximum Allowable Concentrations" of the "Air Pollution Abatement Manual," copyrighted 1951, published by the Manufacturing Chemists' Association, Inc., Washington, D.C. In no event shall any emission from any chimney or otherwise of any solid or liquid particles in concentrations exceed three-tenths grains per cubic foot of the conveying gas at any point. For the measurement of the amount of particles in gases resulting from combustion, standard corrections shall be applied to a stack temperature of 500 degrees Fahrenheit and 50% excess air.

No direct or reflected glare, whether produced by floodlight, high temperature processes, such as combustion or welding, or other processes, so as to be visible from any boundary line of property on which the same is produced shall be permitted. Sky-reflected glare from buildings, or portions thereof, shall be so controlled by such reasonable means as are practical to the end that the sky-reflected glare will not inconvenience or annoy persons or interfere with the use and enjoyment of property in and about the area where such glare occurs.

No discharge at any point into any public sewer, private sewage disposal system, or stream, or into the ground of any materials of such nature or temperature as can contaminate any water supply, interfere with bacterial processes in sewage treatment, or otherwise cause the emission of dangerous or offensive elements shall be permitted except in accordance with standards approved by the Department of Public Health of the State or such other governmental agency as shall have jurisdiction over such activities.
