OnCore Processing LLC · Caught in, under or between running or meshing objects

Injured employee (IE) attempted to provide maintenance on the PU 6 pump belt. As other employee was performing that task, IE removed the keeper that was in place and opened the guard gate to inspect the tension of the belts. The motor immediately began rotating as IE placed hand on the belt. This caused IE's left hand to pull into the belt, causing injury to IE's fingers.
