Investigation of Accidents, Injuries, and Illnesses


Preventing injuries, illnesses, and harmful exposure before they occur is an important goal in the workplace. However, when accidents or “near misses” do occur, they provide a good opportunity to identify health and safety problems and target prevention efforts. 

Accident investigations must be conducted by:

  • Trained supervisors
  • Managers
  • Other knowledgeable persons

Goals of the investigation:

  • Understand why the incident or near miss occurred
  • What actions can be taken to prevent recurrence
  • Timeframe of when actions will be completed
  • Involve work leaders, such as those on the health and safety committee, to participate in the investigations 

The investigation report must be in writing and must adequately identify:

  • Who was injured 
  • Names of any witnesses
  • Cause(s) of the incident or near miss
  • Description of the underlying factors that may have contributed to it
  • What can be done to prevent the incident in the future

Taking the necessary steps after an incident or near miss occurs will help prevent future accidents and will also ensure that workers see the importance of safe practices in the workplace.
