1. What is the primary purpose of a gas pressure regulator in a
distribution system?
A. To increase gas flow
B. To measure gas purity
C. To maintain safe and consistent gas pressure
D. To detect leaks
The regulator ensures that downstream equipment receives gas at
a safe and consistent pressure.
2. Which gas odorant is commonly added to natural gas for leak
detection?
A. Chlorine
B. Mercaptan
C. Sulfur dioxide
D. Ammonia
Mercaptans have a strong odor and are added to otherwise
odorless natural gas for safety.
3. What is the typical maximum allowable operating pressure
(MAOP) for a low-pressure distribution system?
A. 5 psi
B. 15 psi
, C. 60 psi
D. 100 psi
Low-pressure distribution systems are designed to operate below
the MAOP to ensure safety.
4. What is the primary hazard associated with natural gas leaks?
A. Frostbite
B. Explosion and fire
C. Corrosion
D. Noise pollution
Natural gas is highly flammable and can cause explosions if it
accumulates in confined areas.
5. Which method is most commonly used to detect underground gas
leaks?
A. Thermal imaging
B. X-ray scanning
C. Electronic leak detection
D. Acoustic vibration analysis
Electronic detectors sense gas concentrations and are widely used
for underground leak detection.
6. In a cathodically protected steel pipeline, what is the function of
the anode?
A. To measure gas flow
B. To corrode instead of the pipeline
C. To seal the pipeline
D. To regulate pressure
The anode sacrifices itself to prevent corrosion of the steel pipe.
, 7. What is the main purpose of a gas meter?
A. To compress gas
B. To measure gas consumption
C. To add odorant
D. To reduce pressure
Gas meters track customer usage for billing and monitoring
purposes.
8. Which personal protective equipment (PPE) is essential when
working near a live gas pipeline?
A. Gloves only
B. Hard hat only
C. Flame-resistant clothing and gloves
D. Safety glasses only
Flame-resistant clothing protects against fire hazards in case of
leaks or ignition.
9. What is the primary factor that affects the flow rate in a gas
distribution pipeline?
A. Color of the pipe
B. Pipe length only
C. Pressure and pipe diameter
D. Ambient temperature only
Flow rate depends on the pressure differential and the pipe’s
diameter and length.
10. How often should a gas distribution pipeline be inspected for
leaks?
A. Every 5 years
B. Every 10 years
