Propane Fill Certification Practice Test
Questions And Answers Latest Update
Characteristics of Propane - ✔✔✔-is a colorless and odorless gas. Since propane is
odorless, it is intentionally odorized so leaks can be detected. The odor is similar to
rotten eggs.
What affect ambient temperatures have on the expansion of propane - ✔✔✔-
Propane volume rises as temperature rises and falls as temperature falls. Being
temperature dependent, propane becomes more dense as temperature falls and
expands as temperature increases.
The formula used to set the scale of proper filling - ✔✔✔-W.C. (water capacity)
x .42 + T.W. (tare weight)
What affect anhydrous ammonia has on brass - ✔✔✔-NH3 is corrosive to brass,
copper and galvanized components/fittings. When these components/fittings come
in contact with NH3 liquid or vapor, the metal will corrode and will fail.
The propane procedures for filling an rv - ✔✔✔-Set the propane meter to zero.
Connect the motor fuel hose to the tank fill valve.
Open the vent value on the fixed maximum liquid level gauge.
Start the pump and slowly open the hose and valve.
When a steady white mist is emitted, close the hose and valve.
Close the fixed maximum liquid level gauge.
Shut off the pump.
Slowly loosen the filler adapter to prevent any loose propane. Wait until propane
stops venting.
Disconnect and stow the hose assembly once venting has stopped.
Replace the filler valve cap.
