Why smell is not enough to detect a natural gas leak

Natural gas is odorized to make a potential leak easier to detect. However, the odor is only a warning sign and not a measuring instrument.

Subjective perception

The ability to perceive odors varies from person to person and can decrease after prolonged exposure.

Air currents

The odor can be carried away from the actual leak point or diluted in a well-ventilated area.

Small leaks

A very small leak may not be consistently perceived, especially outdoors.

Correct confirmation

The presence and concentration of gas are confirmed with a suitable detector and, where required, with an additional control method.

Basic principle

If there is a suspicion of a leak, do not wait for the "smell to get stronger." Follow the facility's safety procedure.
