The following rerequirements concerning the installation, storage, tank capacity and fire limitations of liquefied petroleum gas (LPG) are hereby established and shall be adhered to:
(a) No LPG system shall be permitted in the Fire Limit Zone, as defined in subsection (v) hereof.
(b) All LPG tanks shall be approved by either A.S.M.E. (American Society of Mechanical Engineers), D.O.T. (Department of Transportation) or B.T.C. (Board of Transit Commissioner of Canada). It will not be necessary for the Fire Department to witness air tests on these tanks. Certification shall be stamped on the tanks.

(d) Tank(s) in excess of 500-gallon aggregate water capacity (w/c), where the LPG is removed as a gas, shall be installed with two regulators.
(e) The installation of a 500-gallon aggregate w/c tank, shall be a minimum distance of ten feet from any building and a minimum distance of ten feet from any property line which may be built upon.
(f) To aid in preventing LPG leaks at the tank, piping and regulator(s) shall be installed as rigidly as possible.
(g) To aid in preventing LPG leaks at buildings, all piping and regulators shall be anchored to the building to prevent their movement.
(h) The opening going through any building wall for LPG piping shall be sleeved for each individual pipe.
(i) All copper piping or tubing shall be Type "K" and one-half inch maximum size only.

(o) Piping shall not be covered until it has been inspected and approved by the Fire Department and after having passed an observed pressure test for thirty minutes using nitrogen or other inert gas or compressed air at a pressure of 200 pounds.
(p) All installations shall be inspected and approved by the Fire Department. This inspection and approval also includes temporary installations. A final inspection of the entire system shall be made by the Fire Department. Under no circumstances shall any LPG product be placed into tanks until this final inspection and approval has been made and a permit has been issued by the Fire Department.
Depending upon the size of LPG tank, a test pressure of 125 pounds shall be accomplished by using compressed air (bottle or compressor) or other inert gas.

The completed fence shall be six feet in height, composed of five-foot high chain link fencing topped by three strands of barbed wire at a forty-five degree angle pointing toward the tank. Fencing shall be a minimum of three feet from the tank(s). Other fencing materials may be used if prior approval of the installation is obtained. Plans of optional fencing must be submitted to the Fire Department for prior approval.
These same installations, when installed in an area subject to damage by motor vehicles, shall be protected by minimum four-inch hollow steel-type heavy duty posts, concrete filled and sloped to shed water, four feet in height, with a minimum of thirty inches embedded below grade and set in concrete. The posts shall be spaced a maximum distance of sixty inches apart and shall be a minimum of ten feet from the tank(s).
