✔✔place marking/metallic tape, place cooper wire with ends exposed, Before backfilling
underground piping, document the actual location of piping in as-built drawings as
follows: - ✔✔Take pictures
✔✔When making a transition from steel to nonmetallic piping: - ✔✔Loin female steel
threads to male non-metallic threads
✔✔Riser piping for fill side typically shall be of __ in. diameter schedule 40 steel piping.
- ✔✔4
✔✔Dispenser risers are commonly how many inches? Schedule 40 pipe or flex
connectors. - ✔✔3
✔✔When air testing newly installed vapor piping, it shall be tested at psig for a period of
___ - ✔✔ hour
✔✔Before air testing piping, as a safety precaution you shall: - ✔✔Isolate piping from
tanks and dispensers
✔✔Lines or tanks that have previously contained hazardous, flammable, or combustible
liquids/vapors shall be tested - ✔✔Shall be tested only after lines are purged and
inerted
✔✔When using a digital manometer, it shall be warmed up for ____ minutes prior to
use. - ✔✔15 (must be calibrated every 90 days)
✔✔A low pressure testing method that evaluates all vapor recovery system components
from the nozzle, through the hanging hardware, the dispenser, the piping, the tank &
tank risers, the vent pipe, & vent cap. - ✔✔Pressure Decay Test
✔✔When performing the Pressure Decay Test, use commercial grade Nitrogen in a
high pressure cylinder capable of maintaining at least __ PSIG of pressure. - ✔✔2000
(2 pressure gauges recommended)
✔✔Hanging hardware does not contain what? - ✔✔Vapor switch
✔✔A test of Stage II vapor-recovery piping that measures the resistance to flow in the
vapor path between the nozzle or dispenser riser and the storage tank. The purpose of
the test is to verify that there are no physical or liquid blockages obstructing the flow of
, vapors in the piping system. (FOR VACUUM ASSIST SYSTEMS ONLY) - ✔✔Dynamic
Pressure Test
✔✔A test procedure that measures the volume of air returned to a storage tank when a
specified volume of gasoline is dispensed from a vacuum-assist vapor-recovery nozzle.
- ✔✔Air to Liquid (A/L) Ratio Test
✔✔A nozzle face seal is located. - ✔✔At the end of the nozzle bellows
✔✔Motor fuels are_a complex mixture of chemicals, many of which are toxic. Before
working around a fuel dispenser, workers should read and understand what? -
✔✔MSDS
✔✔When performing activities that may result in accidental contact with motor fuel, use
the following hand protection: - ✔✔Nitrile Gloves
✔✔If motor fuel accidentally comes in contact with your eyes, ensure you flush your
eyes with water for ____ min and seek medical attention. - ✔✔15
✔✔The shear section of the Vapor Shear Valve must be positioned within ___ in above
or below the level of the top surface of the dispenser island. - ✔✔½ in
✔✔if the flow rate at the dispenser is less than 6.5 GPM replace the following. - ✔✔Fuel
filters
✔✔ESO does not disconnect power to the following: - ✔✔Monitoring Device
✔✔A space that is not designed for continuous employee occupancy. - ✔✔Confined
Space
✔✔Where should the PV vent be tightened? - ✔✔With a suitable wrench from the screw
above the cap
✔✔A Phil Tite rotatable adaptor shall be tightened to a torque between ___ and ___ lbs.
- ✔✔50 to 75 foot lbs
✔✔When installing the OPW drop tube seal the following shall be observed: - ✔✔Install
the install with the special designed drop tube o-ring seal with the flat side against the
drop tube flare
✔✔Where should the OPW drop tube be installed? - ✔✔6 inches from the bottom of the
tank
