I use to work in the oil industry onshore , retired in 2013 , I know you could wear a watch with a battery but weren’t allowed a mobile phone, things need to be intrinsically safe I guess , maybe worth asking the safety department , they should be able to give you some info .might have to get some technical info from Abbott
After getting confused responses from people at Libre, I finally answered the question myself working with Technical experts where I work…
The FreeStyle Libre 2 sensor is powered by an SR626w battery. This battery type has a discharge rate which is below the minimum value ignition capability wattage. Therefore the sensor is safe to wear in a hazardous area offshore (oil/gas platform) - but wearers should always check with their own technical authorities and get approval for their specific location.
