Do any of your good selves know if acetylene training is part of a plumbers NVQ or is this a separate training course. My suspicion is that additional training is required!!! Regards.

It is unlikely that the basic NVQ at level 2 for plumbers , which would include soldering would include the use of acetylene as soldering can be done with propane torches.

I would say additional training is certainly required. This would need to include things like the hazards and properties of gases including oxygen (which is presumably used with the acetylene) the safe use of compressed gas cylinders, flashback arrestors etc. also would need to cover pre use inspection of hoses, cylinders, regulators, torches etc. and that's before you start getting into any practical training which would need to include correct start up/shut down procedures. Most of the compressed gas suppliers can provide this training or put you in touch with their own preferred training providers.
