HAVS Vibration Calculator
Calculate your daily hand-arm vibration exposure A(8) and exposure points. Compare against the Exposure Action Value (EAV) of 2.5 m/s² and Exposure Limit Value (ELV) of 5.0 m/s².

Assumptions
Based on the HSE exposure-points ready-reckoner (approximate); values are guidance only.
EAV 2.5 m/s² A(8) = 100 points; ELV 5.0 m/s² A(8) = 400 points.

HSE Exposure Thresholds
Control of Vibration at Work Regulations 2005 — HAV exposure values.
| Threshold | A(8) | Points | Action required |
|---|---|---|---|
| Below EAV | < 2.5 m/s² | < 100 | Monitor and control |
| EAV — Exposure Action Value | 2.5 m/s² | 100 | Must introduce control measures |
| ELV — Exposure Limit Value | 5.0 m/s² | 400 | Must not be exceeded |
