(a) The LP-Gas Safety Rules
apply to the location and operation of liquefied petroleum gas systems, equipment,
and appliances. These standards also apply to truck and railcar loading racks,
but do not apply to marine terminals, natural gasoline plants, refineries,
tank farms, gas manufacturing plants, plants engaged in processing liquefied
petroleum gases, or to railcar loading racks used in connection with these
excluded establishments.
(1) Subchapter A, General Requirements, applies to various
types of LP-gas activities, including licensing, examination, and training
requirements.
(2) Subchapter B, Stationary Installations and Container Requirements,
applies to proposed and existing stationary LP-gas installations and containers,
including cylinder exchange racks.
(3) Subchapter C, Vehicles and Vehicle Dispensers, applies
to transports and bobtails that deliver LP-gas, and school buses and other
vehicles that are powered by LP-gas.
(4) Subchapter D, Adoption by Reference of NFPA 54
(National Fuel Gas Code), applies to the adoption by reference of NFPA
54 and specifies additional or alternative requirements from those found in
NFPA 54.
(5) Subchapter E, Adoption by Reference of NFPA 58
(LP-Gas Code), applies to the adoption by reference of NFPA 58 and
specifies additional or alternative requirements from those found in NFPA
58.
(6) Subchapter F, Adoption by Reference of NFPA 51
(Standard for the Design and Installation of Oxygen-Fuel Gas Systems for Welding,
Cutting, and Allied Processes), applies to the use of LP-gas as a welding
fuel.
(b) Severability. If any term, clause, or provision of these
rules is for any reason declared invalid, the remainder of the provisions
shall remain in full force and effect, and shall in no way be affected, impaired,
or invalidated.
(c) Nothing in these rules shall be construed as requiring,
allowing, or approving the unlicensed practice of engineering or any other
professional occupation requiring licensure.
(d) Unless otherwise stated, the
LP-Gas Safety Rules are not retroactive.
(e) As stated in Texas Natural Resources Code, Chapter 113,
any LP-gas container with a water capacity of one gallon or less, or any LP-gas
piping system, or appliance attached or connected to such a container is exempt
from the LP-Gas Safety Rules, including any
adopted NFPA pamphlets. For the purpose of consistency, the figure of 4.20
lb is used to determine the weight of one gallon of LP-gas. The omission of
a specific NFPA 58 pamphlet or any other NFPA rule containing any such applicable
language from Table 1 of §9.403 of this title (relating to Sections in
NFPA 58 Not Adopted by Reference, and Adopted With Changes, Additional Requirements,
or Corrections) is inadvertent and shall not be read or understood as requiring
or allowing any such size of LP-gas container to comply with the adopted LP-gas
safety rule requirements.
