Disconnecting Regulator(s).
(Amd) 4-2.2.1 Cylinders or tanks shall be filled, evacuated, disconnected or transported
and regulator(s) disconnected only by the owner or upon the owner's authorization.
At consumer premises where the fixed container is owned by the LP Gas supplier, no
person other than the owner and those authorized by the owner shall connect or disconnect
any cylinder or tank or regulator(s) containing liquefied petroleum gas, whether in
the liquid or vapor state unless the following requirements are met:
(a) Sufficient notice shall be given to the LP-Gas supplier to disconnect and remove
its cylinder or tank or regulator(s) prior to the installation of another cylinder
or tank by the person, firm, corporation or LP-Gas supplier requesting the disconnection.
Sufficient notice shall be in writing received by the LP-Gas supplier or owner a minimum
of four business days prior to the scheduled disconnection on the fourth day. Written
notice shall include the person, firm, corporation or LP-Gas supplier requesting the
disconnection, the address and name of the consumer, and the scheduled date and time
of disconnection. Disconnection by the owner or the owner's authorized agent shall
be coordinated so as not to cause an interruption of service greater than the time
required to disconnect the notified supplier's equipment and reconnect the replacement
equipment of the notifying owner, unless the user authorizes an extended interruption
of service to the notified supplier.
(b) After providing sufficient notice, the person, firm, corporation or LP-Gas supplier
requesting disconnection or transportation may then disconnect the LP-Gas supplier-owned
cylinder(s), tank(s) or regulator(s) downstream of a meter or upstream of a non-LP-Gas
supplier or downstream of a regulator(s) owned by the LP-Gas supplier if connected
to the gas stream, in a manner that renders the cylinder or tank free of leaks, with
valves turned off and all openings plugged, and move on the consumer premises the
cylinder(s) or tank(s), whether empty or full, to a safe location meeting the separation
distance requirements between tanks and cylinders in Table 3-2.2.2.
(c) No person, firm or corporation, other than the owner and those authorized to do
so, shall transport or carry by any means of conveyance whatsoever over public highways
and roads, any cylinder or tank containing liquefied petroleum gas, whether in the
liquid or vapor state.
(d) The owner of the cylinder or tank shall remove the disconnected cylinder, tank
or regulator(s) from the consumer premises within 15 business days after the actual
date and time of disconnection.
(e) If the person, firm, corporation or LP-Gas supplier who requested disconnection
does not disconnect the cylinder(s), tank(s) or regulator(s) on the day of the scheduled
disconnection, the person, firm, corporation or LP-Gas supplier shall be required
to reschedule the disconnection giving sufficient notice to the owner of the cylinder(s),
tank(s) or regulator(s) as described in Section 4-2.2.1 (a).
(f) In the event of an emergency such as the need for domestic heating during extreme
cold weather conditions, leak or fire involving a cylinder, tank or regulator(s),
an LP-Gas supplier is authorized to disconnect or evacuate the cylinder or tank at
the direction of a public emergency response agency such as the fire department.
(Amd) 4-3.3 Emergency Venting. When conditions at any location indicate the need for emergency venting of LP-Gas
into the environment, the local fire department within that jurisdiction or a regional
fire dispatching facility shall be notified prior to any emergency venting activities.
(Amd) CHAPTER 5 STORAGE OF PORTABLE CONTAINERS AWAITING USE, RESALE OR EXCHANGE
(Amd) 5-4.1 Location of Storage Outside of Buildings.
Storage outside of buildings for containers awaiting use, resale or part of a cylinder
exchange point shall be located at least 10 feet from any doorway or opening in a
building frequented by the public; 20 feet from any automotive service station fuel
dispenser and in accordance with Table 5-4.1 with respect to:
(a) Nearest important building or group of buildings;
(b) Line of adjoining property that may be built upon;
(c) Busy thoroughfares or sidewalks;
(d) Line of adjoining property occupied by schools, churches, hospitals, athletic

(Amd) 5-4.2.2 To minimize the possibility of damage to systems, where DOT or ASME container(s)
are stored in any location exposed to vehicular traffic, such as in or near parking
lots, entrances to driveways, streets or construction sites, the systems and containers
shall be protected from motor vehicles and other motorized equipment including but
not limited to cranes, forklift operations and other common hazards by means of a
non-combustible peripheral fence, guardrail or post of metal or concrete, building
walls, or natural or artificial barriers enclosing containers and piping.The presence
of such protection from damage shall not create significant hazards such as pocketing
of LP-Gas, interference with application of cooling water by fire departments, redirection
of flames against containers and impeding egress of personnel in an emergency.
CHAPTER 8 ENGINE FUEL SYSTEMS
(Amd) 8-1.1 This chapter applies to fuel systems and the use of LP-Gas as a fuel for internal
combustion engines. Included are provisions for containers, container appurtenances,
carburetion equipment, piping, hose and fittings and provisions for their installation.
This chapter covers engine fuel systems for engines installed on vehicles for any
purpose, as well as fuel systems for stationary and portable engines. It also includes
provisions for garaging vehicles upon which such systems are installed.
