EXAM — 220 PRACTICE MCQs |
questions , answers & rationales | latest
update
1. Under Florida law, which agency is responsible for licensing and regulating LP gas
dealers and master qualifiers?
A. Florida Department of Agriculture and Consumer Services (FDACS)
B. Florida Department of Agriculture and Consumer Services (FDACS) through the
Bureau of LP Gas Inspection (correct answer)
C. Florida Department of Environmental Protection
D. Florida Public Service Commission
Rationale: FDACS, through its Bureau of LP Gas Inspection, is the state agency responsible for
licensing LP gas dealers, qualifying agents, and master qualifiers, and for enforcing Florida's
LP gas laws and rules.
2. The Florida LP Gas Law is found in which Florida Statute?
A. Chapter 509, F.S.
B. Chapter 527, F.S. (correct answer)
C. Chapter 553, F.S.
D. Chapter 489, F.S.
Rationale: Chapter 527, Florida Statutes, governs the manufacture, storage, distribution, sale,
and use of LP gas in Florida, including licensing of dealers and master qualifiers.
,3. LP gas is primarily composed of which of the following?
A. Methane and ethane
B. Propane and butane (correct answer)
C. Natural gas and hydrogen
D. Acetylene and oxygen
Rationale: Liquefied petroleum (LP) gas is primarily composed of propane (C3H8) and butane
(C4H10), which are byproducts of natural gas processing and crude oil refining.
4. The specific gravity of propane vapor compared to air is approximately:
A. 0.5 — lighter than air
B. 1.5 — heavier than air (correct answer)
C. 1.0 — equal to air
D. 2.5 — much heavier than air
Rationale: Propane vapor has a specific gravity of approximately 1.5 relative to air (which is
1.0), meaning propane vapor sinks to the lowest point and can accumulate in low-lying areas,
creating explosion and fire hazards.
5. The boiling point of propane at atmospheric pressure is approximately:
A. +32°F (0°C)
B. -44°F (-42°C) (correct answer)
C. -100°F (-73°C)
D. +14°F (-10°C)
Rationale: Propane boils at approximately -44°F (-42°C) at atmospheric pressure. This means it
vaporizes readily at normal ambient temperatures, making it suitable for use as a fuel in most
climates.
,6. When LP gas is in liquid form inside a container, the pressure above the liquid is called:
A. Operating pressure B. Vapor pressure (correct answer) C. Static pressure D. Atmospheric
pressure
Rationale: Vapor pressure is the pressure exerted by the gas phase of LP gas above the liquid
surface within a closed container. It varies with temperature — increasing as temperature rises.
7. What is the approximate BTU content per gallon of propane?
A. 62,000 BTU B. 91,502 BTU (correct answer) C. 1,020 BTU D. 50,000 BTU
Rationale: One gallon of propane contains approximately 91,502 BTUs of heat energy. This
value is important for sizing LP gas systems and calculating consumption rates.
8. Under NFPA 58, the minimum distance from a container of 500 gallons water capacity to
a building or line of adjoining property is:
A. 5 feet B. 10 feet (correct answer) C. 25 feet D. 50 feet
Rationale: NFPA 58 (Liquefied Petroleum Gas Code) requires that containers of 500 gallons
water capacity be located at least 10 feet from buildings or adjoining property lines.
9. The "water capacity" (WC) of an LP gas container refers to:
A. The amount of water used to cool the container B. The weight of water in pounds the
container would hold if completely filled with water (correct answer) C. The maximum LP
gas content in gallons D. The cooling water jacket volume
Rationale: Water capacity is used as a standard measure for LP container sizing. Since LP gas
containers should not be filled to 100% liquid full, WC provides a basis for calculating fill
limits.
10. LP gas containers should be filled to a maximum of what percentage of their water
capacity?
A. 100% B. 80% at 60°F, using the appropriate fixed liquid level gauge or variable gauge
(correct answer) C. 90% D. 70%
, Rationale: NFPA 58 requires LP gas containers be filled to a maximum of 80% of water
capacity at 60°F to allow for liquid expansion due to temperature increases, preventing
container overpressure.
11. A "master qualifier" under Florida law is best described as:
A. A licensed plumber who installs gas lines B. An individual who has passed the Florida LP
Gas Master Qualifier examination and is responsible for the LP gas activities of a licensed
dealer (correct answer) C. A federal inspector from the DOT D. A licensed contractor with a
general license
Rationale: A master qualifier is an individual who has demonstrated competency by examination
and is designated as the responsible party for the LP gas dealer's compliance with Florida LP
gas laws and regulations.
12. The qualifying agent of an LP gas dealership is responsible for:
A. Only the financial operations of the dealership B. All LP gas activities conducted by the
dealer, including compliance with safety standards and Florida law (correct answer) C.
Only the training of delivery drivers D. Only container installation
Rationale: Under Florida law, the qualifying agent (master qualifier) is personally responsible
for ensuring the dealer's LP gas operations comply with Chapter 527 F.S. and applicable codes
and standards.
13. Which standard is adopted by Florida as the primary LP gas code for installation and
safety requirements?
A. NFPA 54 B. NFPA 58 (correct answer) C. NFPA 70 D. NFPA 101
Rationale: Florida adopts NFPA 58, the Liquefied Petroleum Gas Code, as the primary
standard governing LP gas storage, handling, installation, and distribution in the state.
14. The relief valve on an LP gas container is designed to:
A. Prevent the container from being overfilled B. Open and release vapor if internal pressure
exceeds a safe level, preventing container rupture (correct answer) C. Allow liquid
withdrawal from the container D. Measure the pressure inside the container
