Connecticut (CT) P-9 Contractor Gasoline Tank, Piping,
and Pump Exam | Latest Verified Questions and
Detailed Answers
OVERVIEW DESCRIPTION:
This comprehensive set of multiple-choice questions is designed for the Connecticut P-9
Contractor Gasoline Tank, Piping, and Pump Exam, a computer-based, open-book test
administered by PSI Exams. The exam assesses mastery of petroleum piping and tank
installation, safety standards, and environmental compliance, with emphasis on NFPA 30,
30A, 329, and OSHA 29 CFR 1926, as well as EPA and Connecticut DEEP requirements for
spill prevention, leak detection, secondary containment, and proper testing and
maintenance procedures.
QUESTION 1
According to NFPA 30, an aboveground storage tank with a capacity of 10,000 gallons
storing a Class I flammable liquid and equipped with emergency relief venting not
exceeding 2.5 psig must be separated from a property line that can be built upon by a
minimum of:
A. 5 ft
B. 10 ft
C. 15 ft
D. 25 ft
CORRECT ANSWER: C
EXPERT RATIONALE: NFPA 30 Table 22.4.1.1(b) mandates a 15 ft minimum separation
for Class I liquids in tanks of that capacity.
QUESTION 2
Which NFPA standard specifically addresses safeguards for motor fuel dispensing
facilities and repair garages?
,2|Page
A. NFPA 30
B. NFPA 30A
C. NFPA 31
D. NFPA 329
CORRECT ANSWER: B
EXPERT RATIONALE: NFPA 30A is the Code for Motor Fuel Dispensing Facilities and
Repair Garages, covering pumps, dispensers, and piping at service stations.
QUESTION 3
In a motor fuel dispensing area, an emergency shutoff button must be readily accessible
and located no more than what distance from each dispenser?
A. 20 ft
B. 50 ft
C. 75 ft
D. 100 ft
CORRECT ANSWER: D
EXPERT RATIONALE: NFPA 30A requires an emergency shutoff device located within 100
ft of the dispensers and clearly identified.
QUESTION 4
A shear valve (impact valve) installed at the base of a gasoline dispenser is designed
primarily to:
A. Regulate flow during fueling
B. Shut off fuel flow if the dispenser is struck or knocked over
C. Filter debris from the fuel stream
D. Vent excess pressure from the product line
CORRECT ANSWER: B
,3|Page
EXPERT RATIONALE: The shear valve automatically closes to prevent fuel release when
the dispenser is impacted, isolating the piping below the breakaway point.
QUESTION 5
When a breakaway coupling is required at the hose on a motor fuel dispenser, it must
separate without releasing more than which maximum amount of liquid?
A. 1 ounce
B. 5 fluid ounces
C. 1 pint
D. 1 gallon
CORRECT ANSWER: B
EXPERT RATIONALE: NFPA 30A allows no more than 5 fluid ounces of spillage upon
separation of the breakaway device to minimize fire risk.
QUESTION 6
NFPA 329 is best described as a recommended practice for:
A. Installing underground storage tanks
B. Handling releases of flammable and combustible liquids and gases
C. Vapor recovery system design
D. Electrical classification of dispensing areas
CORRECT ANSWER: B
EXPERT RATIONALE: NFPA 329 provides guidance on procedures for investigating and
mitigating releases of flammable and combustible liquids and gases.
QUESTION 7
According to OSHA 1926 Subpart P, which soil type requires a maximum allowable slope
of 1½:1 (34 degrees) for excavations less than 20 ft deep?
A. Stable rock
, 4|Page
B. Type A soil
C. Type B soil
D. Type C soil
CORRECT ANSWER: D
EXPERT RATIONALE: Type C soil is the least stable; OSHA mandates sloping at 1½:1
(34°) for excavations up to 20 ft unless other protective systems are used.
QUESTION 8
In an excavation greater than 4 ft deep where hazardous atmospheres exist or could
reasonably be expected, OSHA requires:
A. Daily visual inspection only
B. Atmospheric testing before entry and as needed
C. A ladder at the entry point only
D. No special precautions
CORRECT ANSWER: B
EXPERT RATIONALE: 1926.651(g) requires testing the atmosphere in excavations where
oxygen deficiency or a hazardous atmosphere is a possibility before employee entry.
QUESTION 9
Under EPA UST regulations (40 CFR 280), all new underground storage tanks must have
a leak detection method that monitors:
A. The tank’s exterior coating only
B. The interstitial space of a secondarily contained tank or a continuous electronic
monitoring system
C. Monthly inventory reconciliation alone
D. Visual inspection of tank surface every five years
CORRECT ANSWER: B
