Hi all, Just a quick question, Looking at vibration measurements for a rail saw. Front handle is 5.5m/s and the rear handle is 4.2m/s. Do i add these together and take measurements as if it would be 9.7m/s or take them as 2 separate ones and add the exposure together? Both results are miles apart. Cheers Karl

I would have only take the higher value of the two and base your exposure levels, risk assessment and controls on the 5.5m/s2

On a similar note, a jack hammer is used with both hands, expriencing the same vibration exposure levels. One hand is clenched to keep the jammer working - does this affect blod flow / health hazard?
