Abstract

The method includes the following steps: (i) About a reference point, a sensor is exposed to the atmosphere in a plurality of different directions until the sensor registers the transient presence of a critical component of the leaking gas above a threshold level, thereby to indicate a suspect direction, the sensor being exposed without mixing of the atmosphere; (ii) A second reference point is then selected in the suspect direction relative to the first reference point. Step (i) is then repeated about the second reference point.
