So to summarize, the grinder vibration value is decreased from 6.0 m/s² to 3.5 m/s² and the trigger time is reduced from 2 hours to 1 hour and 30 minutes. The hammer vibration value would be decreased from 30 m/s² to 10 m/s², and the exposure duration remains unchanged at 15 minutes per 8-hours. Let’s now enter these values into the HAV exposure calculator to determine the HAVS risk.
