These HAV tool tags are a practical, visual reminder that a particular tool produces vibration and will contribute to an operative’s daily hand–arm vibration exposure. They are intended to be fitted directly to individual tools so that vibration is considered before use, rather than after exposure has already accumulated.

The tags are colour-coded based on the measured vibration level of the tool. Green is typically used for tools measured below 2.5 m/s², orange for tools in the 2.5–4.9 m/s² range, and red for tools measured at 5 m/s² or above. A red tag does not mean a tool must not be used; it indicates that this is not a tool that can be used without considering what other vibration-producing tasks are being carried out during the day, whether the tool is appropriate for the job, and how long it is used for.

Each tag shows the measured vibration level for the tool, along with the maximum recommended usage time and HSE exposure points per hour. For tools that are typically used for short periods - such as impact wrenches or reciprocating saws - points per minute are also shown to support more realistic exposure tracking.

The tags are robust and suitable for use in demanding environments. Multiple fixing holes allow flexible attachment using cable ties, and the surface can be written on using a suitable marker without the information rubbing off.
