Home - Safety - Vibration - Vibration Exposure Limits - DEWALT

Exposure limits are calculated as a combination of the vibration level (magnitude) of the tool and the Daily Exposure Time (Trigger Time). E.g. A product with 5m/s² vibration can be used up to 2 hours/day to reach the EAV and up to 8 hours/day to reach the ELV. Exposure Action Value (EAV) - Daily vibration exposure A(8) = 2.5m/s²
