Current through Register 2024 Notice Reg. No. 38, September 20, 2024
S.1.
Design of Liquefied Petroleum Gas Tanks.
S.1.1. Tank Requirements. Liquefied petroleum
gas tanks when used as measures shall be so constructed and marked to fully
comply with all requirements of the California State Department of Industrial
Relations whenever such Department has jurisdiction pertaining to liquefied
petroleum gas tanks.
S.1.2.
Completeness of Delivery. A tank shall be so constructed that, when it is
standing on a level surface, complete delivery can be made.
S.2. Design and Location of Liquefied
Petroleum Gas Tank Gaging Devices.
S.2.1.
General. A dip pipe shall be so designed that it will distinctly and
unmistakably define a capacity point when liquid is in contact with the lowest
portion of the dip pipe.
S.2.2.
Number of Dip Pipes. When any tank is used as a measure, it shall be provided
with one or more dip pipes, one of which shall indicate between 86 percent and
87 percent of the actual total capacity of the tank.
S.2.3. Permanently Installed. Except as
provided in S.2.5. and S.2.6., dip pipes shall be permanently installed as an
integral part of the tank.
S.2.3.1.
Cylindrical Tanks. Dip pipes on a cylindrical tank shall be installed with the
location of the internal opening of the dip pipe or dip pipes on a line with
the longitudinal axis of the tank midway between the ends. For the purpose of
this article, "midway" means that the internal opening of the dip pipe or dip
pipes shall not be more than 6 inches from the actual midway distance between
the ends of the tank.
S.2.3.2.
Spherical Tanks. The dip pipe or dip pipes on a spherical tank shall be
installed with the location of the internal opening or openings of the dip pipe
or dip pipes in line with the vertical axis of the tank.
S.2.4. Openings. The internal opening of a
dip pipe shall be not less than one-quarter inch standard iron pipe size, for
at least the first two inches above the liquid, and the internal opening of the
dip pipe shall be parallel to the surface of the liquid and shall approach the
liquid through the vapor space when the tank is plumb and level. The maximum
opening of the bleeder valve shall be a number fifty-four drill size.
S.2.5. Dip Pipes on Valves. Dip pipes which
are fastened to a valve or valves and are so installed as to be removable from
the container and which are less than one-quarter inch standard iron pipe size
shall be permitted only on containers of five hundred pounds water capacity or
less.
S.2.6. Removable Dip Pipes.
Removable dip pipes may be used on containers having a capacity in excess of
five hundred pounds if the opening and at least the first two inches of the dip
pipe above the liquid is not less than one-quarter inch standard iron pipe
size. Provision shall be made so the dip pipe or dip pipes may be sealed in
place by a weights and measures official in such a manner their position cannot
be changed or the dip pipe or dip pipes be removed without destroying or
mutilating the seal or seals.
S.3. Marking of Capacity. Each liquefied
petroleum gas tank used as a measure shall be plainly and conspicuously marked
with its capacity. This marking shall appear on the rear or side of the tank,
adjacent to the outage indicator valve, in letters, figures, or numerals not
less than 3/4 inch in height and not less than 1/2 inch in width. On
tanks having one calibrated capacity, the marking shall indicate the tank
capacity to the nearest gallon and shall also indicate without qualification
that the capacity is measured to the dip pipe. In the case of a liquefied
petroleum gas tank having more than one calibrated capacity, the marking
required by this section shall indicate the capacity applicable to the
respective dip pipe.
A marking statement may be expressed in terms of percentage
of fill (i.e., 86 1/2%), if followed by the required marking which states the
calibrated capacity in terms of gallons to the dip pipe.
Each and all letters, figures or numerals required by this
section shall be of like color or tint and shall contrast with the background
of such sign or designation. The required markings shall be the responsibility
of the owner of the liquefied petroleum gas tank.
