What does a gas odor test involve?

A gas odor test specifically involves assessing the presence of added odorants in natural gas. Natural gas is inherently odorless, and to ensure safety, a distinctive odorant (usually mercaptan) is added so that leaks can be easily detected. During the gas odor test, personnel will check for this odor to confirm that the gas has been treated with the appropriate additive and to ascertain that there are no leaks.

While temperature measurement, pressure testing, and visual inspections are important aspects of overall gas maintenance and safety checks, they do not directly pertain to the specific purpose of the gas odor test, which is focused solely on detecting odorants in the gas.
