(a) Stationary LP-gas installations, including LP-gas
transfer systems, dispensing systems, and storage containers, shall
be protected from tampering and damage as specified in this section.
(b) LP-gas storage containers located on a rural consumer's
property from which motor or mobile fuel containers are filled are
not required to comply with the fencing and vehicular barrier protection
requirements in subsections (c) and (d) of this section.
(c) In addition to NFPA 58, §§6.21.4.2, 6.22.3.2(3),
6.27.3.7, 8.2.1.1, and 6.5.4.5, fencing at LP-gas installations shall
comply with the following:
(1) Uprights, braces, and cornerposts of the fence
shall be composed of noncombustible material and shall be anchored
in concrete a minimum of 12 inches below the ground.
(2) Gates in fences where bulkheads are installed shall
be located directly in front of the bulkhead. Gates shall be locked
whenever the area enclosed is unattended. Gate posts on gates installed
directly in front of the bulkhead shall be located at 45-degree angles
to the nearest corner of the bulkhead.
(3) ASME containers or manual dispensers originally
manufactured to or modified to be considered by AFS as self-contained
units are exempt from the fencing requirements. Self-contained units
shall be protected as specified in subsection (d) of this section.
(4) LP-gas containers located at a private residence
are exempt from the fencing requirements.
(d) In addition to NFPA 58, §§6.8.1.2, 6.8.6.1(A)-(E),
6.8.6.2(F), 6.27.3.13 and 6.27.3.14, vehicular barrier protection
at LP-gas installations, except as noted in this section, shall comply
with the following:
(1) Vertical supports for vehicular barrier protection
shall be at least three-inch schedule 40 steel pipe or other material
with equal or greater strength. The vertical supports shall be capped
on the top or otherwise protected to prevent the entrance of water
or debris; anchored in concrete at least 18 inches below the ground;
and rise at least 30 inches above the ground. Supports shall be spaced
four feet apart or less.
(2) The horizontal guardrailing for vehicular barrier
protection shall be secured to the top of the vertical supports at
least 30 inches above the ground. The railing shall be at least three-inch
schedule 40 steel pipe or other material with equal or greater strength.
The railing shall be capped on the ends or otherwise protected to
prevent the entrance of water or debris; and welded or bolted to the
vertical supports with bolts of sufficient size and strength to prevent
damage to the protected equipment under normal conditions, including
the nature of the traffic to which the protected equipment is subjected.
(3) Locations which have a perimeter fence prohibiting
public traffic to the container or cylinder storage area shall not
be required to have guardrailing if the vertical supports are located
no more than three feet apart.
(4) Openings in horizontal guardrailing, except the
opening that is permitted directly in front of a bulkhead, shall not
exceed three feet. Only one opening is allowed on each side of the
guardrailing. A means of temporarily removing the horizontal guardrailing
and vertical supports to facilitate the handling of heavy equipment
may be incorporated into the horizontal guardrailing and vertical
supports. In no case shall the protection provided by the horizontal
guardrailing and vertical supports be decreased. Transfer hoses from
the bulkhead shall be routed only through the 45-degree opening in
front of the bulkhead or over the horizontal guardrailing.
(5) Clearance of at least three feet shall be maintained
between the vehicular barrier protection and any part of an LP-gas
transfer system or container or clearance of two feet for retail service
station installations. The two vertical supports at the ends of any
vehicular barrier protection which protects a bulkhead shall be located
a minimum of 24 and a maximum of 36 inches at 45-degree angles to
the nearest corner of the bulkhead.
(6) Vehicular barrier protection shall extend at least
three feet beyond any part of the LP-gas transfer system or container
which is exposed to collision damage or vehicular traffic.
(7) Installations which have highway barriers located
between vehicular traffic and the container and material handling
equipment shall not be required to have vehicular barrier protection
installed.
(e) If exceptional circumstances exist or will exist
at an installation which would require additional protection such
as larger-diameter horizontal railing, then the licensee or operator
shall install such additional protection. In addition, AFS at its
own discretion may require an installation to be protected with added
safeguards to adequately protect the health, safety, and welfare of
the general public. AFS shall notify the person in writing of the
additional protection needed and shall establish a reasonable time
period during which the additional protection shall be installed.
The licensee shall ensure that any necessary extra protection is installed.
If a person owning or operating such an installation disagrees with
AFS' determination made under this subsection, that person may request
a public hearing on the matter. The installation shall either be protected
in the manner prescribed by AFS or removed from service with all product
withdrawn from it until AFS' final decision.
(f) In addition to NFPA 58 §5.2.8.1, LP-gas installations
shall comply with the sign and lettering requirements specified in
Table 1 of this section. An asterisk indicates that the requirement
applies to the equipment or location listed in that column.
Attached Graphic
(1) Unless colors are specified, lettering shall be
in a color that sharply contrasts to the background color of the sign,
and shall be readily visible to the public.
(2) Items 1, 2, and 3 in Table 1 may be combined on
one sign.
(3) Items 1, 2, and 3 in the column entitled "Licensee
or Non-Licensee ASME 4001+ Gal. A.W.C." in Table 1 apply to installations
with 4,001 gallons or more aggregate water capacity protected only
by vehicular barrier protection as required in subsection (d) of this
section, and bulkheads as required by §9.143 of this title (relating
to Bulkhead, Internal Valve, API 607 Ball Valve, and ESV Protection
for Stationary LP-Gas Installations with Individual or Aggregate Water
Capacities of 4,001 Gallons or More) for commercial, bulk storage,
cylinder filling, or forklift installations.
(4) Item 7 in the column entitled "Storage Racks for
DOT Portable or Forklift Containers" in Table 1 may be met with lettering
only one rack when multiple racks are installed.
(5) Item 11 in the column entitled "Requirements" in
Table 1 applies to facilities which have two or more containers.
(6) Item 13 in the column entitled "Requirements" in
Table 1 applies to outlets where an LP-gas certified employee is responsible
for the LP-gas activities at that outlet, when a licensee's employee
is the operations supervisor at more than one outlet as required by §9.17(a)
of this title (relating to Designation and Responsibilities of Company
Representative and Operations Supervisor).
(7) Any information in Table 1 of this subsection required
for an underground container shall be mounted on a sign posted within
15 feet horizontally of the manway or the container shroud.

and/or procedural actions specified by the signage requirements of
this section.
(9) Any 24-hour emergency telephone numbers shall be:
(A) monitored at all times; and
(B) be answered by a person who is knowledgeable of
the hazards of LP-gas and who has comprehensive LP-gas emergency response
and incident information, or has immediate access to a person who
possesses such knowledge and information. A telephone number that
requires a call back (such as an answering service, answering machine,
or beeper device) does not meet the requirements of this section.
(g) In addition to NFPA 58, §8.4.2.2, storage
racks used to store DOT cylinders in the horizontal position located
in areas frequented by the public shall be protected against vehicular
damage by:
(1) the use of concrete curbs and/or wheel stops provided:
(A) the cylinder storage rack is located a minimum
of 48 inches behind a curb or wheel stop that is a minimum of five
inches in height above the grade of the driveway or parking area;
(B) if the requirements of subparagraph (A) of this
paragraph cannot be met, the cylinder storage rack must be installed
a minimum of 48 inches behind a curb or wheel stop that is a minimum
of four inches in height above the grade of the driveway or parking
area, and a wheel stop at least four inches in height must be installed
at least 12 inches from the curb or first wheel stop; and
