Hand-arm vibration (HAVS) exposure calculator

Enter each tool's vibration magnitude and how long it is used (the trigger time). Using the HSE exposure points system, this works out the exposure points, your daily exposure A(8), and whether you are approaching the exposure action value (2.5 m/s²) or the exposure limit value (5 m/s²). Free, no account needed.

Trigger time is the actual contact ("trigger") time, not the whole task. Use the manufacturer's declared or a measured magnitude — the examples are rough guides only.

Enter at least one tool's magnitude and trigger time to see the result.

Indicative only. This uses the HSE exposure points method (EAV = 100 points / 2.5 m/s² A(8); ELV = 400 points / 5 m/s² A(8)) and is a screening estimate, not a substitute for a proper vibration risk assessment. Confirm figures against the HSE guidance and, where needed, a competent assessment.

Manage vibration exposure properly

Complys keeps your hand-arm vibration assessments, exposure records and the health surveillance those exposures require — so nothing is missed and the programme can be evidenced.
