A recent International Marine Contractors Association (IMCA) safety flash (01/16) contains details of an incident where a commercial diver collapsed due to low oxygen content of what was believed to be air which was supplied to him. Fortunately this occurred on the surface and there was no long term impact.
This incident is a useful reminder of the importance of testing diving gas before use.
As most service divers should be aware, it is mandatory for testing of Compressed Natural Breathing Air (CNBA) used by AT divers to be completed using a FACTAIR F2235. As part of this test, the oxygen content should also be tested using an Analox Oxygen Analyser and this forms part of the FACTAIR F2235 kit.
It is hoped that by the use of the FACTAIR F2235 and Analox Oxygen Analyser incidents like that above can be avoided by AT divers.
