  • Happened;
  • Was the injury;
  • Was your employee doing when they had their accident; and
  • Equipment was the person using?


  • Did the incident happen;
  • Did your employee start the work they were doing;
  • Did their manager tell them to do the task; and
  • Did their manager last check how they were doing?


  • Did this incident injure your employee;
