## Narrative

EE got on his knees to check the oil in the water truck.  When he tried to stand up his right knee locked up.  We think this is an occupational illness because he didn't do anything to cause a tear in his knee.  There is nothing he or anyone could have done to prevent this.  There is no accident.  This shouldn't be considered a work injury but an illness.
