Reactive or “sticky” gases pose additional issues when it comes to gas detection. As their name suggests, they react with many of the surfaces with which they make contact. This becomes a particular problem if the atmosphere to be tested is being “sampled” rather than tested directly.
A common question we encounter at Crowcon is when to use a pump or aspirator with a portable gas detection device. I’d like to share some thoughts about the use of personal detectors with pumps or aspirators as part of an effective confined space pre-entry check.
