New Mexico (NM) LP-3S Retail Sale of LP Gas
Practice Exam 2
Which of the following is a primary design requirement for vehicles
transporting LP-Gas?
A. High-speed capability
B. Reinforced cargo compartment
C. Enhanced fuel efficiency
D. Aesthetic design - CORRECT ANSWER-Answer: B
Explanation: LP-Gas cargo tank vehicles must have reinforced
compartments to safely contain the pressurized gas and protect against
impacts.
Cargo tank vehicles must be constructed using materials that are:
A. Lightweight and decorative
B. Resistant to corrosion and high pressure
C. Economical regardless of safety
D. Easily replaceable after minor damage - CORRECT ANSWER-
Answer: B
Explanation: Materials resistant to corrosion and capable of
withstanding high pressures are critical to prevent leaks and ensure
long-term structural integrity.
,What is the main purpose of safety relief valves in LP-Gas vehicles?
A. To increase the flow of gas during loading
B. To automatically vent pressure in the event of over-pressurization
C. To measure the quantity of gas delivered
D. To regulate engine performance - CORRECT ANSWER-Answer:
B Explanation: Safety relief valves are designed to release excess
pressure, thereby preventing damage or explosion.
Cargo tanks for LP-Gas must be designed to withstand:
A. Extreme cold only
B. Pressure surges and environmental factors
C. Overloading by excess gas
D. High-speed collisions exclusively - CORRECT ANSWER-Answer: B
Explanation: These tanks are built to handle pressure variations and
environmental challenges, ensuring safe operation under varying
conditions.
Which certification is often required for the design of LP-Gas cargo
tanks?
A. ISO 9001
B. DOT (Department of Transportation) approval
,C. EPA certification
D. OSHA compliance only - CORRECT ANSWER-Answer: B
Explanation: DOT approval is critical to verify that the design and
construction meet federal safety standards for hazardous materials.
A vehicle transporting LP-Gas should be equipped with which of the
following to ensure safety?
A. Extra seating capacity
B. Secure, labeled storage compartments
C. Multimedia navigation systems
D. Aesthetic modifications - CORRECT ANSWER-Answer: B
Explanation: Proper labeling and secure storage help in quickly
identifying the cargo and ensuring that it is safely secured during transit
Why is proper insulation important in the construction of LP-Gas cargo
tanks? A. To reduce noise during transport
B. To maintain a consistent internal temperature and prevent
condensation
C. To make the vehicle more attractive
D. To increase the tank's weight - CORRECT ANSWER-Answer: B
Explanation: Insulation helps in maintaining a stable temperature,
which is critical for the safety and stability of LP-Gas.
, Which of the following best describes the construction requirement for
the welds on an LP-Gas cargo tank?
A. Decorative and robust
B. High-quality, continuous, and inspected
C. Quick and inexpensive
D. Minimal, to reduce production costs - CORRECT ANSWER-Answer:
B
Explanation: Weld quality is paramount; continuous and properly
inspected welds ensure the tank's integrity under pressure.
What role does the tank's design play in the event of an impact?
A. It minimizes the vehicle's overall cost
B. It disperses energy and reduces the risk of rupture
C. It maximizes the gas capacity
D. It provides better aerodynamics - CORRECT ANSWER-Answer: B
Explanation: A robust design helps in absorbing and dispersing impact
energy, reducing the risk of tank rupture.
Cargo tank vehicles must meet which of the following structural integrity
tests?
A. Speed and acceleration tests
B. Pressure and leak tests
C. Fuel consumption tests
