Generate a risk assessment for noise and vibration exposure in UK construction. Covers action values, HAV, WBV, hearing protection, and health surveillance.
Frequently asked questions
- What are the noise exposure action values?
- The lower exposure action value is 80 dB(A) daily — requiring hearing protection availability and information. The upper action value is 85 dB(A) — requiring mandatory hearing protection, hearing protection zones, and health surveillance.
- How do I calculate HAV exposure?
- You need the vibration magnitude of each tool (available from manufacturers or the HSE's vibration database) and the daily trigger time. The HSE's ready-reckoner or online calculator converts these into a daily exposure value.
- What is health surveillance for noise and vibration?
- For noise, it means regular audiometry (hearing tests) for workers above the upper action value. For vibration, it means regular questionnaires and, where indicated, medical assessment of hands and fingers.
