Control of Vibration at Work Regulations 2005 (SI 2005/1093)

WBV Daily Exposure Calculator

Calculate a worker's daily whole-body vibration exposure for plant operators and vehicle drivers. Choose the A(8) method for continuous or regular vibration, or the VDV method for shocks and intermittent vibration. Compare against the legal Exposure Action Value (EAV: 0.5 m/s², 100 points) and Exposure Limit Value (ELV: 1.15 m/s², 529 points).
