When something stops working, you rarely get a heads-up.  When was the last time you flipped a switch, only for your light bulb to give up the ghost?  Or have you had a cold, frosty morning this winter when your car simply won’t start?

Deadly sin no.1- not calibrating

We recently ran a series of articles call the “Seven Deadly Sins of Gas Detection”. By highlighting the most common causes and effects of each ”sin”, we wanted to provide managers and employees with a greater awareness of what we believe are the Seven Deadly Sins of gas detection, how to avoid them and save lives. For the same reason, we are sharing them as our blog posts for the next seven weeks.

Detecting VOCs with PID – how it works

Having recently shared our video on pellistors and how they work, we thought it would make sense to also post our video about PID (photo-ionisation detection). This is the technology of choice for monitoring exposure to toxic levels of another group of important gases – volatile organic compounds (VOCs).

Pellistor sensors – how they work

Pellistor gas sensors (or catalytic bead gas sensors) have been the primary technology for detecting flammable gases since the ‘60s. Despite having discussed a number of issues relating to the detection of flammable gases and VOC, we have not yet looked at how pellistors work. To make up for this, we are including a video explanation, which we hope you will download and use as part of any training you are conducting

Getting yourself out of a hole

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.
