HAVS Calculator

The HAVS calculator is designed to help users assess the risk of HAVS by calculating the vibration exposure level of tools or processes.

EAV: 2.5 m/s² A(8), or 100 points. ELV: 5 m/s² A(8), or 400 points.

The HAVS calculator is designed to help users assess the risk of HAVS by calculating the vibration exposure level of tools or processes. It provides estimates on exposure points per hour, time to reach Exposure Action Value (EAV), and Exposure Limit Value (ELV), helping users manage and limit exposure to hand-arm vibration.

If you require an offline version of a HAVS Calculator, we recommend downloading the HSE HAVS Calculator.

What are EAV and ELV?

EAV (Exposure Action Value) and ELV (Exposure Limit Value) are thresholds set for vibration exposure. EAV is the level above which employees should be informed of the risks to health and preventive actions taken. ELV is the maximum amount of vibration an employee may be exposed to on any single day.

Measuring Vibration Magnitude

Vibration magnitude should be measured using a hand-arm vibration meter. Accurate measurements allow employers to calculate exposure and ensure compliance with vibration regulations.
