we also did some Oxygen cleaning and Bruno has his own idea of how that can be achieved. Good thinking Bruno!

As part of the
equipment repair course and the
Gas Blender course we used the sonic bath to clean parts of a 1st stage of a regulator. Usually I conduct the
equipment repair course simultaneously with the blender course, since it takes time in between Nitrox tanks to fill up, time we use for having a closer look at some pieces of equipment.

After a long day of academics, exams, hands on cleaning and tank fills we were glad to get the group picture out of the way and finish the day, from left to right, Olivier, Bruno, me, David and Craig.
