(a) Automatic fuel dispensers shall be
				  fabricated of material suitable for LNG and resistant to the action of LNG
				  under service conditions. Pressure containing parts shall be stainless steel,
				  brass, or other equivalent cryogenic material. Aluminum may be used for
				  approved meters.
(b) Electric
				  installations within dispenser enclosures and the entire pit or open space
				  beneath dispensers shall comply with NEC, Class 1, Group D, Division 1, except
				  for dispenser components located at least 48 inches above the dispenser base

										RSA
				  14.2101 of this title (relating to System
				  Protection Requirements).
(e) A
				  device shall be installed in the liquid piping so that displacement of an
				  automatic dispenser will result in the displacement of such piping on the
				  downstream side of the device.
(f)
				  The fueling nozzle shall prevent LNG from being discharged unless the nozzle is
				  connected to the vehicle.
(g) A
				  key, card, or code system shall be used to activate the automatic
				  dispenser.
(h) Automatic dispensers
				  shall incorporate cutoff valves with opening and closing devices which ensure
				  the valves are in a closed position when dispensers are deactivated.
(i) LNG fuel storage installations which
				  include automatic dispensers shall be equipped with an emergency shut-down
				  device for the entire LNG installation located at least 20 feet from the
				  nearest dispenser or storage area. The emergency shut-down device shall be
				  distinctly marked for easy recognition in compliance with the requirements of
				  §
										RSA
				  14.2101 of this title.
(j) If automatic dispensers are to be used
				  during hours of darkness, permanent adequate lighting shall be provided to
				  facilitate proper operations.
(k)
				  Fuel dispensers, including automatic dispensers, may be operated only by an
				  individual who has been properly trained.
(1)
				  The licensee owning, operating, or servicing a CNG fuel dispensing facility
				  shall ensure the safe operation of the system and provide training to
				  users.
(2) Step-by-step operating
				  instructions provided by the manufacturer shall be posted at or on each
				  automatic dispenser, readily visible to the operator during transfer
				  operations. The instructions shall describe each action necessary to operate
				  the automatic dispenser and include the location of and procedure for
				  activating emergency shutoff equipment.
(3) Each person or entity who operates a fuel
				  dispenser, excluding an automatic dispenser, shall be provided with written
				  instructions and safe operating procedures by the licensee. The person
				  operating the dispenser should be cautioned to study and preserve such
				  instructions and procedures.
