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

HAVS Daily Exposure Calculator

Calculate a worker's daily hand-arm vibration exposure in m/s² A(8) and HSE exposure points. Compare against the legal Exposure Action Value (EAV: 2.5 m/s², 100 points) and Exposure Limit Value (ELV: 5.0 m/s², 400 points). Select from all 41 HSE reference tools or enter your own measured values.

Above action value (EAV). Control measures required. Health surveillance needed.

·Risk assessment required.
·Investigate lower-vibration tool alternatives and anti-vibration gloves.
·Limit trigger time — rotate tasks between workers.
·Establish a health surveillance programme for exposed workers.
·Provide information and training.
