The NFPA code that applies to propane dispensers located at multiple fuel
refueling stations is _____
,30A
The valves and fittings required by NFPA 58 for ASME tanks typically used to
supply propane dispensers include a double backflow check filler valve, a spring-
type relief valve, a fixed maximum liquid level gauge, and a _______
Float Gauge
Two additional ASME tank fittings (devices) required for ASME tanks a over
4,000 gallons water capacity that are not required by NFPA 58 for ASME tanks
typically used to supply propane dispenser are a ______
Pressure gauge, Temperature gauge
An ASME tanks ______ is used to determine the discharge capacity requirements
for its relief valve(s)
Data Place
Means such as a _______ (designed to remain in place, except during pressure
relief device operation, and not restrict pressure relief device flow) shall be
provided to minimize the possibility of the entrance of water or other extraneous
matter into the tank's relief device or any discharge piping.
Rain Cap
Dispenser supply tank over 4,000 gallons water capacity or having a filling
opening ______ diameter or larger require a transfer bulkhead equipped with an
emergency shutdown valve (ESV) for the vapor equalizing connection (if 1 1/4
inch or larger), and an ESV for the liquid fill connection. A backflow check valve
may be used for the liquid line if flow of liquid is limited to one direction (into the
dispenser supply tank).

LP-Gas Code for ignition source control and those of ______ for hazardous
NFPA 70
_______ in electrical area classifications are based upon the likelihood of the
presence of a flammable mixture of materials located in the area.
Divisions
Which of these items is not a primary component of a dispenser electrical system?
Sealing Fitting; Remote Shute off Switch; Explosion Proof Switch; Octagon
Electrical Box
Octagon Electrical Box
If no sealing fitting is provided at the boundary between classified and non-
classified areas, or if the lower portion of the fitting is not properly sealed with
sealing compound, the entire system ______ as an explosion-proof system
Does not meet the code
The primary consideration in selecting a pump for a dispenser that will be
primarily used to fill smaller cylinders is to select a pump with minimal gallon per
minute to minimize the risk of ______
Overfilling
If a dispenser installation is primarily used to fill larger, vehicle mounted mobile,
or motor fuel tanks at a filling station or fleet service center, a ______ pump
should be considered to reduce filling time and minimize operator waiting that
could contribute to lack of attention during the filling operation.
Large
If the power supply at the site will only support low-voltage, single phase electric
motors, the pump size and volume must be matched to the _____
Electrical Supply
