The accident occurred on 9/25/19, but it didn't become reportable until EE went to doctor on 10/03/19. EE first noticed pain while pulling wrenches on the Haver bag placer, one in each hand, to either loosen or tighten. Then moved to hammer to help move a bolt. Moved back to wrenches and pain got worse. Pain present along forearm to palm near thumb on right hand.
