The Chief of the Fire Department

adjacent property, shall require
each container to be surrounded by
a dixie of such capacity as may be
considered necessary but not more
than the capacity of the container.
SECTION x: Piping shall be
wrought iron, steel, brass or cop
per pipe; or approved seamless
copper, brass or other approved
non-ferrous tubing which shall have
a wall thickness of not less than
0049 inch. All piping for conveying
gas or liquid shall be suitable for a
safe working pressure of not less
than 125 pounds. All piping for con-
veying gas or liquid shall be tested
and proven free from leaks at l1a
times the pressure to which it ma"
be subjected.
Joints in wrought iron and steel
piping shall be of welded con-
struction, or shall be made with
fittings capable of Withstanding a
pressure of at least 1875 pounds per
square inch for pressure less than
100 pounds per square inch; extra
heavy fittings shall be used for
pressureS exceeding 100 pounds per
square inch. Cast-iron fittings shall
not be used. Joints on brass or cop
per pipe, or approved seamless cop
per, brass or other approved nom

Piping or tubing shall be run as
directly as practicable without says,
or traps; provision shall be made
for expansion, contraction, jarring
and vibration and for settling of
container. At points where piping
passes through walls, suitable pro-
vision shall be made to insure gas
tightness and all piping and tubing
shall be tested and proven tight
after all connections have been
made.
Piping outside buildings shall be
protected against mechanical in
jury.
SECTION XI: The filling pipe
inlet terminal shall not be located
inside a building. On all containers
where inlet terminal prevents its
location adjacent to the container,
the inlet terminal shall be enclosed
in a substantial manner so as to
prevent mechanical injury and
tampering by unauthorized persons.
Such terminal shall be located not
less than 10 feet from any building
and where practicable not less than
5 feet from any driveway and shall
be kept locked when not in use.
All containers, other than cylin-
ders and drums complying with I.
C. c. specifications, shall have all
connections, except relief connec-
tions, equipped with approved au-
tomato excess flow valves, provided,
however, that fill connections shall
be equipped with approved back
pressure check valves, to prevent
discharge of contents in case con-
nections are broken. These excess
] flow and back-pressure check valves
shall be located inside of the con-
tainer or at point outside where
the line enters the containers; in
