Question 1
Compared with air, how does natural gas normally behave after a leak in an open room?
Correct Answer:
It tends to rise because it is lighter than air
Explanation:
Natural gas has a specific gravity lower than air, so leaked natural gas generally tends to rise and disperse upward when ventilation is available.
Question 2
Inside a typical LP storage cylinder or tank, propane is stored primarily in what form?
Correct Answer:
Primarily as a liquid with vapor above it
Explanation:
LP gas is stored primarily as a liquid under pressure. Vapor above the liquid is drawn off, and more liquid vaporizes as vapor is used.
Question 3
Why is an odorant added to commercially supplied natural gas?
Correct Answer:
To make leaks detectable by smell
Explanation:
Processed natural gas is naturally odorless, so an odorant is added to help people detect a leak by smell.
Question 4
Which approximate heating value is commonly used for quick field calculations with natural gas?
Correct Answer:
1000 Btu per cubic foot
Explanation:
A common field approximation is about 1000 Btu per cubic foot for natural gas, although the actual utility-supplied value can vary.
Question 5
Which method is appropriate for checking a gas fitting for leakage after service?
Correct Answer:
Apply an approved leak-detection solution or use an electronic detector
Explanation:
Gas joints should be checked with an approved leak-detection solution or suitable electronic leak detector. An open flame must never be used for leak testing.
