1. 1. One of the significant causes of leaks in underground liquid storage
systems is : Improper Installation
2. 2. Written Plans are required to: obtain permits, solicit bids, and provide precise
guidance for installers.
3. 3. The plans should: Describe the property, identify the size and location of the
tanks, indicate the liquids to be stored and provide the location of the dispensers
and piping.
4. 4. Storage systems discussed in this recommended practice are usually
regulated by: Federal, state or local agencies.
5. 5. All owners should ensure that the equipment to be installed meets: applic-
able regulatory requirements before being installed
6. 6. Consult the local authorities who have jurisdiction in the area before
storage-system plans are: finalized or construction is initiated.
7. 7. All owners should ensure that the equipment to be installed meets all
applicable regulatory requirements before: Being installed.
8. 8. To avoid damage tanks must not be: dropped, dragged, or handled with
sharp objects.
9. 9. Tanks must not be dropped, dragged, or handled with sharp objects to
avoid: Damage to the tank
10. 10. The only time tanks really should be moved is when: for inspections and
testing.
11. 11. If a tanks is damaged at all throughout the moving process it must
be: Repaired in accordance with the manufacture's instructions.
12. 12. The proper way to move a tank is by lifting it, using the: Lift lugs that are
installed by the manufacturer.
13. 13. Tanks should be carefully lifted and lowered using: Cables or chains of
adequate length.
14. 14. When two lifting lugs are being used, the angle between the lifting cable
and vertical should be no more than: 30 degrees.
15. 15. Stockpile piping materials and equipment in a
on the job site: Secure area
16. 16. Confirm adherence to specifications by reporting to the owner about
any: detected damage that could result in leakage or premature corrosion.
17. 17. Pressure test single-walled tanks with to psig air pres-
sure, soaping all surfaces, seams and fittings while inspecting for bubbles.: 3
to 5
18. 18. Air testing with over psig (3 Psig for 12-Ft. Diameter FRP tanks) is
hazardous and may damage the tank: 5 psig
, U1 UST Installation/Retrofitting questions and answers
19. 19. Do not air test a tank that has previously contained: flammable or
combustible liquids
20. 20. Place barricades at the ends of tanks being tested.: Warning
21. 21. Avoid tank ends, man-ways, and fittings while the tank is under: Pres-
sure
22. 22. Release pressure in the tank before disconnecting any: gauges or test
fittings.
23. 23. Be aware some manufactures do not tighten fittings to allow for
during shipping and storage.: Temperature
changes
24. 24. True or False: Air tests are inconclusive without soaping and careful
inspection for bubbles?: True
25. 25. Tanks gauges must have a scale that will permit detection of
small changes in that might go undetected on gauges with a
.: Pressure, broader range.
26. 26. Since the best accuracy of gauges is at mid-range, and test pressures
must not exeed 5 psig, use a gauge with a maximum limit of or : 10
or 15 psig
27. 27. Check the gauges and before use: operation and
accuracy
28. 28. Underground storage systems may include vapor-recovery: Piping and
equipment
29. 29. What can cause premature storage-system failures : Debris
and other foreign materials
30. 30. Tank installers should have gone through training programs to improve
their skills and insure the install is : Successful
31. 31. kinds of plans are required to obtain permits, solicit bids,
and provide precise guidance for installers: written
32. 32. should insure that the equipment to be installed
meets all applicable regulatory requirements before beginning an installation-
: Owners
33. 33. Tanks should be inspected before installation: Visually
34. 34. 2 Gauges should be used to reduce : gauge
failure
35. 35. A pressure-relief device should e used to prevent
: Over pressurization
36. 36. True of False: Over pressurization could be a result of temperature
changes: True
