HAVS: time to daily exposure thresholds by ComplyOnSite
Horizontal axis: vibration magnitude (m/s²). Vertical axis: minutes to daily thresholds. Higher vibration magnitudes reach the daily action and limit values sooner. The curves show one tool used at a constant magnitude, with no other vibration exposure that day. Use the ComplyOnSite HAVS calculator to combine tools and actual trigger times.
Two curves show minutes to daily vibration exposure thresholds decreasing as tool vibration magnitude rises from 2.5 to 20 metres per second squared. At 5 m/s² the action value is reached at 120 minutes and the limit at 480 minutes; at 10 m/s² they are reached at 30 and 120 minutes.
