16 Tex. Admin. Code § 9.141 - Uniform Safety Requirements
(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.
