If the alarm continues for • onehour, e: it quitepossible thatthe monitorin, <br />environment or background has already been contaminated with certain toxic gas or hydroc& <br />bons. To verity whether the alarm is caused by contamination, simply remove the vapor sensc <br />from the monitoring well, and place it in clean air, if the alarm continues, then the alarm set poir <br />is •• sensitive and hence, should be readjusted. On other hand, if the alarm stops, <br />confirms that, indeed the monitoring well has been contaminated.
