What is Incident Investigation?


If a workplace incident results in an injury, or could have caused a serious injury, both employers and WorkSafeBC have certain responsibilities. Incident investigations help identify the cause and hazards, while finding ways to prevent similar incidents from happening in the future.

Employer investigations


  • Employers are responsible for conducting investigations related to incidents that happen in their workplaces and submitting employer incident investigation reports (EIIRs) to WorkSafeBC.
  • Depending on the incident and how serious it is, employers may also need to immediately report the incident to WorkSafeBC.
  • Employers are responsible for completing reports to represent the four stages of an investigation: preliminary investigation, interim corrective actions, full investigation, and full corrective actions.


Incidents requiring an investigation


Employers are responsible for immediately conducting an investigation into any incident that involves:

  • Serious injury to a worker or a worker's death
  • Injury requiring medical treatment
  • Minor injury, or no injury, but had the potential for causing serious injury
  • Major structural failure or collapse
  • Major release of hazardous substances
  • Diving incident, as defined by the Occupational Health and Safety (OHS) Regulation
  • Dangerous incident involving explosive materials
  • Blasting incident causing personal injury

Investigating Serious Injuries and Fatalities in the Workplace


Unfortunately, the consequences of workplace injuries and deaths are always tragic. The focus of our investigations is to ensure that as investigators we see beyond the tragedy so that we can determine the cause of the incident and establish whether or not it was the result of criminal negligence.
