• *Note: Use the above ‘ready reckoner’ table by finding the vibration magnitude (m/s) and going across to where it reaches EAV, this will give you the exposure action value. We should be aiming not to go over this level. Alternatively punch the information into the exposure calculator

  

• Vibration Magnitude m/s (if over 2.5 m/s2) ?

• EAV time allowed on tool (use the table* or online calculator https://www.hse.gov.uk/vibration/hav/vibrationcalc.htm#:~:text=arm%20vibration%20calculator-,Hand%2Darm%20vibration%20exposure%20calculator,-If%20you%20have) ?

• Duration on tool in hrs & Min ?

• Over/under exposure?

  Under

  Over

If exposure is above the action value of 2.5m/2 (A8), Control measures to be implemented as followed
