Hi, I'm looking for advice on plasma cutters. training requirements, RA's etc. I'm looking into using them on cast iron tanks to reduce Vibration and noise as we are currently using reciprocating saws which are not ideal. Any help very welcome!

I can probably help with the risk assessment (but not today). However, I would be cautious - what was in the tanks?

In my experience - Do NOT underestimate the sheer quantity of smoke and fume which will be generated, it is huge. And even if done outside expect possible calls to emergency services. Whilst you will reduce the risk to HAVS make sure you dont increase other health risks - inhalation. Im guessing your recip saws are likely giving you 15m/s (on paper) and 25+ in practice. Grinders may give 5m/s and 8m/s but take longer and generate more noise and dust. Depending on the budget and location you also have the option of UHP water cutting or wire cut (I have seen some massive metal structures being cut using a near silent and clean wire cutting machine) - google gave me this (not affiliated) http://www.bdnuclear.co.uk/metal-wire-sawing/18/ Des

Don't underestimate the material changes that you could impart into Cast Iron with a hot cut as opposed to a cold cut either, if the process is not metallurgically compatible, and will not give you the desired end product then removing the HAVS risk is irrelevant as the work will no longer be possible.
