On 7-30-19, EE was emptying 2A bin at old plant when dust blew into eye. EE self-treated by flushing eyes with water. (Note: Prior to this, EE experienced weld flash burn to eyes at EE's residence the weekend of July 27-28, 2019.) EE worked remainder of day on 7-30-19, as well as 7-31-19. Still having burning in eye, EE went to ER on evening of 7-31-19 & received treatment.
