Hand, Arm, Vibration Testing (HAVS)

HAVS testing involves measuring an appliance that vibrates to ensure it is safe to use based on its application and duration of use

HAVS Measurement Services

Our engineers have been trained to use specialist equipment to measure the vibration of a tool when it operated in a way that is representative of the task it is to be used for. So if a drill is to be used for drilling into concrete then the measurement should take place when it is actually drilling concrete.

HAVS is commonly seen in people who regularly use high vibration equipment. Groups of employees especially at risk are those that regularly use hand tools or machines that produce high levels of vibration e.g..

  • concrete pokers
  • chainsaws
  • circular saws
  • concrete breakers
  • sanders
  • grinders
  • disc cutters
  • hammer drills

Our services include:

  • Testing, tagging and re-certification
  • Creating and maintaining a HAVS equipment register / database
  • Tracking when equipment is due a re-test and sending out a reminder when that date approaches


The Control of Vibration at Work Regulations 2005 sets an Exposure Action Value (EAV). This is the daily amount of occupational exposure an operator can absorb, above which employers are required to take action. It is based on vibration readings for equipment that varies for different types of tool, the operating conditions, how well maintained the tool is and the amount of time spent operating the tool.

Depending on the vibrations readings the tool is identified as:

  • Red - more then 5m/s²

  • Amber - between 2.5m/s² and 5m/s²

  • Green - less then 2.5m/s²
