EAV & ELV

Overview

take action and the absolute limits that must not be exceeded. The EAV is the level at which employers must begin to reduce exposure and provide health surveillance — the ELV is the maximum permissible daily exposure. Thes e values are expressed in metres per second squared — m/s² — and are calculated as an eight-hour energy -equivalent exposure — A(8) — accounting for both the vibration magnitude and the duration of exposure.
