<br />gallons capacity to conform to the
<br />National Fire
<br />Protective Assoca.tion
<br />standards.
<br />Tanks shall be riveted, welded or brazed, and shall be soldered, caulked
<br />or otherwise made tight in mechanical and workmanlike manner, and, if to be
<br />used with a pressure discharge system, shall safely sustain a hydrostatic test
<br />at least double the pressure to which the tank may be subjected; top of tank to
<br />be securely fastened to top ring with joints of equal tightness to those between
<br />rings. Said tanks shall be covered with asphaltum or other non -rusting paint
<br />or co��ting. All pipe connections shall be made through flanges or reinforced
<br />metal securely riveted, welded or bolted to tank and made thoroughly tight.
<br />The use of wooden top tanks is prohibited.
<br />Tanks shall be constructed entirely or metal, including top, sides, and
<br />bottom; all openings shall be gas tight, except beneath the vent which shall
<br />be screened. All tanks shall be electrically grounded by resting directly on
<br />moist earth or otherwise electrically grounded to permanent moisture, preferably
<br />to water piping and to the satisfaction of the City Electrician and Chief of
<br />the Fire Department. No insulated connection shall be permitted. Telephone or
<br />similar poles or other projections liable to act as discharge points shall be
<br />kept as far as practicable from tanks.
<br />' If buried underground, said tank or tanks shall be lower than floors,
<br />basements, cellars or pits of all buildings within a radius of 50 ft. The top
<br />of the tank shall also be at least 3 feet under the ground and below any piping
<br />to which the tank may be connected. Except in lieu of the three feet of earth,
<br />tanks may be buried under 1811 of earth and covered with reinforced concrete at
<br />least 6" in thickness which shall extend at least one foot beyond the outline of
<br />the tank in all directions; said concrete shall be set on a firm foundation and
<br />be surrounded with soft earth or sand, well stamped into place or encased in
<br />concrete. Tank may have a test well, provided the test well extends to near
<br />the bottom of the tank and twelve feet above the source of supply and top shall
<br />be hermetically sealed and locked except when necessarily open. The tank shall
<br />have a vent pipe at least lit in diameter which shall extend from the top of
<br />the tank to at least 12 feet above ground level and shall terminate in a goose
<br />neck protected in the outer end by a 40x40 mesh or equivalent non -corrodible wire
<br />screen.
<br />If erected above ground, said tank shall conform to the same specifications
<br />and requirements as heretofore outlined and in addition said tank shall be
<br />erected only on steel or metal supports of sufficient size and thickness for
<br />carrying the load to be im,_,osed thereon and on a concrete foundation.
<br />SEC. 320 (5) GASOLINE, BENZINE, NAPTHA, AND OTHER FLAMMABLE LIQUIDS -
<br />PERMIT.
<br />No tank for the storage of gasoline, benzine, natha or other highly volatile
<br />liquid of more than 10 gallons capacity shall be installed without a written permit
<br />from the City Manager. The fee for such permit shall be $1.00 for each tank
<br />installed.
<br />All above ground tanks shall, when deemed necessary by the City Manager,
<br />on account of proximity to streams or nearness to public property or buildings
<br />of high value, which may be endangered, be dyked or the entire yard, together
<br />with contiguous or adjoining yards upon approval by the City Manager, may be
<br />provided with a curb or retaining wall or other suitable means taken to prevent
<br />the discharge of liquids onto other property in case of a rupture in tank or piping.
<br />Said dykes or walls shall be of earth or masonry so constructed as to afford
<br />adequate protection. The capacity of the dykes shall be properly maintained and
<br />earthen dykes shall have a slope consistent with the angle of repose of the materials
<br />of which they are constructed.
<br />All installations under the authority of this section shall be under the
<br />'
<br />direction and meet with the approval of the City Manager, and all such installations
<br />shall be made in a workmanlike manner and in accordance with recognized standards
