1. What is the primary purpose of regulations governing liquefied
petroleum gas (LPG) dealers?
A. To increase fuel prices
B. To control customer usage only
C. To ensure safe handling, storage, and distribution of LPG
D. To eliminate all competition
Answer: C. To ensure safe handling, storage, and distribution of LPG
Rationale: LPG regulations exist to protect the public, employees, and
property by establishing requirements for safe storage, transportation,
installation, and dispensing of propane and other liquefied petroleum
gases.
, 2. Liquefied petroleum gas is commonly stored as a liquid because:
A. It becomes nonflammable when liquid
B. It occupies less space under pressure
C. It loses its energy value when vaporized
D. It cannot be transported as a gas
Answer: B. It occupies less space under pressure
Rationale: LPG is compressed into a liquid state to reduce volume, allowing
practical storage and transportation while maintaining usable fuel energy.
3. The main component of commercial propane odorant is added to:
A. Increase pressure
B. Improve combustion
C. Help detect leaks
D. Reduce vapor formation
Answer: C. Help detect leaks
Rationale: Propane is naturally odorless, so an odorant such as mercaptan
is added to help people recognize gas leaks.
4. The boiling point of propane at atmospheric pressure is
approximately:
,A. 32°F
B. -44°F
C. 100°F
D. 212°F
Answer: B. -44°F
Rationale: Propane boils at approximately -44°F, allowing it to vaporize
readily under normal environmental conditions.
5. A propane dealer’s primary responsibility when delivering fuel is to:
A. Fill tanks beyond capacity
B. Follow safe delivery procedures
C. Ignore equipment condition
D. Avoid customer communication
Answer: B. Follow safe delivery procedures
Rationale: Dealers must ensure safe delivery practices, including
inspections, proper filling procedures, and compliance with safety rules.
6. The maximum filling level of a propane container is limited mainly to:
A. Prevent corrosion
B. Allow liquid expansion
, C. Increase fuel pressure
D. Reduce fuel quality
Answer: B. Allow liquid expansion
Rationale: Containers are not filled completely because propane expands
when temperature increases, creating dangerous pressure conditions.
7. The liquid expansion of propane can cause:
A. Lower tank pressure
B. Container rupture
C. Loss of odorant
D. Fuel freezing
Answer: B. Container rupture
Rationale: Liquid propane expands significantly with temperature changes
and requires vapor space to prevent excessive pressure buildup.
8. The vapor pressure of propane increases when:
A. Temperature decreases
B. Temperature increases
C. The container is emptied
D. The odorant is removed
Answer: B. Temperature increases
