I am presently investigating the link between hand held washing guns and RSI injuries in relation to the trigger action.

I am finding it hard to source the equipment and what tool would be best to assess the equipment. I have Qec at present but the sourcing of specific had gun is the issue

Daniel,

there are lots of different makes of pressure washer, all with different ways of reducing the risk of RSI, for example, egonmic handles, locking buttons which allow the washer to operate and allows the operator to waggle his fingers at the same time, soft grip handles etc. Rather than limit your assessment to RSI (if thats what you have done), broaden it to include all WRULDs including those that may be triggered by vibration.
Pressure washers that just "spray" aren't too bad re vibration, hopwever, those that have a "pulse" mode do cause reasonably high levels of vibration. Add to that the probability of cold, wet, lack of movement in the hand etc????

Also, as a rule of thumb, dont believe manufacturers stated vibration levels, guidance recommends doubling these or carrying out your own monitoring. Check out the HSE website for the vibration matrix.
