Every person owning, leasing or operating a line of wires over streets,
ways or buildings in the City shall use only wires that are suitable and strong,
shall suitably and safely attach them to strong and sufficient supports, and
insulate them at all points of attachment, shall remove promptly all wires
the use of which has been permanently discontinued, shall not permit an unused
piece of electric wire to be left on the surface of any street or sidewalk,
nor an unused coil or loose end of an electric wire to remain attached to
a post, pole or crossarm for more than 24 hours, shall suitably and safely
insulate every wire where it enters a building and, if such wire is other
than a wire designed to carry an electric light or power current, shall attach
to it at suitable and convenient places along the circuit, and especially
near the place of its entry into the building, an appliance calculated to
prevent, beyond the point at which such appliance is attached, the continuance
of, and to prevent at all times from entering the building, a current of electricity
of such intensity or volume as to be capable of injuring electrical instruments
or causing fire within the building.
No wire shall be installed or operated over or across any street, way,
building or structure in the City which may at any time seriously interfere
with or obstruct the work or convenience of the Fire Department in the use
of ladders or of other fire apparatus, or which may at any time obstruct or
render hazardous the use of fire escapes. On complaint of the Chief of the
Fire Department, the Inspector of Wires shall see that all such interfering,
obstructing or hazardous wires are removed or safely and properly rearranged.
Except where impossible or inexpedient, signal wires shall not be carried
on the same pole or supports with or in other dangerous proximity to high
potential electric light or power wires, and where a joint occupancy pole
or support carrying wires of these two classes is necessary, or where routes
traversed by wires of these two classes cross each other, high potential electric
light or power wires shall be placed and maintained not less than four feet
apart from any such signal wires, and where it is impossible to provide for
such separation, it shall be the duty of the Inspector of Wires to arrange
and enforce a safe and equitable alternative plan.
