located at least 5 ft horizontally from any opening in the building below the level of
discharge. - correct answer-
Above ground ASME tanks must be positioned so that the relief valve discharge is
located at least 5 ft horizontally from any opening in the building below the level of
discharge. - correct answer-
Above ground tanks with less than ____ gallons water capacity may be placed next
to a building in must be at least ____ feet horizontally from any building opening that
is below the level discharge. - correct answer-125/5

According to DOT requirements, which of the following containers cannot be
transported on public roadways to the customer site? - correct answer-A 1000 gallon
ASME tank containing 100 gallons of liquid propane.
According to NFPA 54 a pressure test applies pressure of not less than __ times the
proposed maximum working pressure of the interior piping, but in no case less than
__ psig. - correct answer-1 and 1/2
, 3
According to NFPA 58 requirements for above ground lines, you can use PE pipe,
tubing, and fittings in above ground line installations. True or false? - correct
answer-False
According to NFPA 58, if any underground tank isn't protected from damage due to
vehicle traffic, then how many inches below grade mass in underground tank beware
vehicle traffic is expected to cross the location of the tank? - correct answer-18
inches
According to the NFPA 58 requirements, which of the following is a requirement for
piping installation? - correct answer-Vapor distribution system piping can never be
used as a grounding electrode.
After the interior distribution system is installed, inspected for NFPA 54 code
requirements, and is ready to be placed into operation, the meter or regulator will
have to be connected to the interior system. This assessment will be conducted after
the connections are made between the exterior and interior portions of the system,
subsequent to the installation of the container, piping, and regulators. True or false? -
correct answer-False
All containers filled on site at the point of use must be positioned so that the filling
connection, the relief valve discharge and the fixed maximum liquid level gauge vent
discharge are situated at least 10 ft from: - correct answer-any source of ignition
such as window air conditioners or pool heaters.
An opening into direct-vent appliances
