| (a) In addition to NFPA 58, §6.8.1.4, containers
shall be painted as follows:
(1) ASME containers, except vaporizers, shall be painted
white or aluminum, or any other heat-reflective color (such as light
green, light blue, etc.). Darker, heat-absorbing colors (such as black,
navy blue, etc.) shall not be permitted.
(2) If AFS disapproves of a certain color, the licensee
or ultimate consumer shall provide to AFS information from the container
or paint manufacturer stating specific reasons why the color is heat-reflective
and should be approved. The AFS director shall make the final determination
and shall notify the licensee or ultimate consumer.
(b) In addition to NFPA 58, §6.27.4.2, each LP-gas
private or public motor/mobile or forklift refueling installation
which includes a liquid dispensing system shall incorporate into that
dispensing system a breakaway device.
(1) Any vapor return hose installed at such installations
shall also be equipped with a breakaway device.
(2) LP-gas installations at which forklift cylinders
are completely removed from the forklift before being filled are not
required to have a breakaway device.
(3) In addition to NFPA 58, §6.27.4.1, the overall
length of hose on vehicle fuel dispensers used to transfer LP-gas
into engine fuel and mobile containers on vehicles shall not exceed
18 feet measured from the point where the hose attaches to rigid piping
downstream of the pump to the end of the dispensing hose. If a section
of hose not exceeding 36 inches in length is installed for flexibility
between the listed emergency breakaway device and the rigid piping
downstream of the pump, then the 18 feet of dispensing hose will be
measured from the outlet of the emergency breakaway device.
(c) Any ball-type shutoff valve less than two inches
in size shall have a locking handle. If a ball-type shutoff valve
of any size has a locking handle installed at the terminal end of
the hose, the main liquid and/or vapor valves or main shutoff valves
on the stationary container at an attended installation may remain
open as long as the locking handle on the transfer hose remains locked
until the transfer hose is properly connected. If a ball-type shutoff
valve two inches or larger in size does not have a locking handle,
the main liquid and/or vapor valves or main shutoff valves on the
stationary container shall remain closed at all times and shall not
be opened until the transfer hose is properly connected or disconnected.
(d) A retail operated service station installation
shall be equipped with a pump.
(e) In addition to NFPA 58, §5.2.8.1, all containers
shall be numbered in accordance with the requirements set forth in
Table 1 of §9.140 of this title (relating to System Protection
Requirements).
(f) In addition to NFPA 58, §6.5.4.1, no canopies
or coverings are allowed over any stationary ASME container of 125
gallons or more or over loading and unloading areas where LP-gas transport
transfer operations are performed. Non-combustible wind breaks and
other weather protection may be installed in accordance with NFPA
58, §6.7.1.1 and §6.25.3.3 to provide employees and customers
protection against the elements of weather, but shall not be installed
over any portion of an LP-gas container.
(g) Any container that may have contained product other
than LP-gas shall be thoroughly cleaned and purged prior to introducing
LP-gas into such container. Only grades of LP-gas determined to be
noncorrosive may be introduced into any container. LP-gas may not
contain anhydrous ammonia, hydrogen sulfide, or any other contaminant.
(1) If it is known or suspected that the LP-gas has
been or may be contaminated, the person responsible for the contamination
shall have one or more of the tests contained in "Liquefied Petroleum
Gas Specifications for Test Methods, Gas Processors Association (GPA)
2140" performed by a testing laboratory or individual qualified to
perform the tests. AFS may request information necessary to determine
the qualification of any testing laboratory or individual.
(2) The results of the tests shall certify whether
the LP-gas is contaminated or corrosive, whether the use of the LP-gas
in the containers will damage either the stationary or non-stationary
containers or the container valves, fittings, or appurtenances, or
whether the contaminated product or container or container valves,
fittings, or appurtenance will endanger the health, safety, and welfare
of the general public.
(3) Based on the results of the tests, AFS may require
that the LP-gas be removed immediately from the container or that
the container be removed immediately from LP-gas service.
(h) A container designed for underground installation
only shall not contain liquid fuel at any time the container is aboveground
or uncovered.
(i) Racks used to store cylinders awaiting use or resale
shall be installed on firm, level ground. In addition to NFPA 58 §8.4.1.1,
a distance of five feet shall be maintained between the rack and any
sources of ignition and combustible materials.
