Generate a risk assessment for hand-arm vibration (HAV) in UK construction. Covers exposure action values, tool selection, rotation schedules, and health surveillance.
Frequently asked questions
- What are the HAV action and limit values?
- The daily exposure action value (EAV) is 2.5 m/s² A(8) and the exposure limit value (ELV) is 5 m/s² A(8). Employers must take action to reduce exposure at the EAV and must not exceed the ELV.
- How do I calculate HAV exposure?
- You need the vibration magnitude of each tool and the daily trigger time. The HSE's online calculator or ready-reckoner tool converts these into a daily A(8) exposure value.
- What health surveillance is needed?
- Health surveillance includes regular questionnaires about symptoms and, where indicated, clinical assessment. Workers exceeding the EAV should be under health surveillance.
