HAVS Exposure Calculator

A(8), action value and limit value explained

Enter the vibration magnitude and daily trigger time for each tool your team uses. We calculate HAV exposure points and the daily A(8) value for each tool and in total, and show you where you stand against the action value (100 points) and the limit value (400 points).

The old way of assessing vibration risk

Skip the spreadsheet. Let the sensor do the risk assessment.

Manual calculations rely on manufacturer figures and estimated trigger times, and have to be redone every time a tool or task changes. The HAVS Protect sensor measures each worker's actual exposure on every tool, all day, and keeps the documentation up to date automatically.
