We have identified a potential problem with vibration but this is a whole new area for me. We have several laboratory grinders which are transmitting vibration through the work surfce and floor to standing operatives.
As far as the CVaWR 2005 go our work fits the definition of WBV (2 (1) but all the HSE guidance I have found relates specifically to that caused by vehicles etc.
We clearly need to assess the risks and implement some controls but can any one point me in the right direction of further guidence. I assume we will need measure magnitude and exposure etc but I am unsure whether this can be acheived in house or we need to bring in a specilaist.

Only measuring arrangement for WBV I'm aware of involves seated operator. Perhaps a chat with an anti-vibration engineering solution company would be a better bet. You have some options, including isolating the floor or isolating the machines. Anti-fatigue floor matting might be enough. Could be something as simple as the washers on the grinder mountings needing replacement. Have operators reported any issue or discomfort?

Thanks Ron,
Its something that was considered on supply, in fact I obtained some AV foam and fitted to our first grinder along with enough for additional units. Installtion was signed over to the line managers. I have been involved in reviewing the risk assessments due to some other issues including dust and a possible HAV matter. While conducting observations and questioning it becam apparrent operators were feeling some discomfort thorough floor transmission (modular building with wooden floor).
I am currently looking at other controls including AV mounts and antifatigue mats, as we may reconfigure the benches I can also look at the bench - floor - wall interface.
My main concern was that I was missing some obvious duty to measure or something. I guess if new controls remove or reduce the discomfort then we have achieved our aim.
Thanks again
Jon

I suspect that AV mounts or matting may not be of much use on a floating type floor. It may well be necessary to brace the floor as well to provide a firmer foundation.

Thanks Colin, I will bear that in mind.
We have mats and mounts on one unit and this helps, but not clear at the moment if its enough. what this space!
