Struck by flying object
Had a problem with the stacker, went to shut machine down. When running under the belt, the operator lost footing and fell resulting in EE's hard hat to fall off. When EE stood back up to put the hard hat on, a rock came off the belt hitting EE in the head. Went to urgent care, just an open laceration. No stitches required, but did go home for the rest of the day.
