Employer incident investigations: the preliminary and full reports the Act requires
An excavation contractor’s operator needs medical treatment after a hand injury. The owner records the incident in the daily diary but has not assigned the employer investigation or checked the preliminary-report clock.
Check the investigation duty immediately. WorkSafeBC identifies incidents requiring employer investigation, including medical-treatment injuries and events with serious-injury potential even without serious harm. Its process distinguishes preliminary investigation, interim corrective actions, full investigation and final corrective actions. The preliminary investigation and report are due within 48 hours unless WorkSafeBC grants an extension; the full investigation and report must be completed and submitted within 30 days. Read the current requirements, including participation and report distribution, for the actual incident.
Keep four stages and their receiving records connected
- Establish the duty and capable participants. Identify the actual employer and event, using the current investigation categories and appropriate advice for uncertain application. Receive people knowledgeable about the work and the required employer and worker-representative participation, if or as available. Keep the separate immediate serious-incident report in view. A team investigating for the employer does not replace the regulator’s investigation or establish technical permission to restart affected work.
- Receive the preliminary findings and interim response. Record the available sequence, observations and significant contributing conditions without presenting speculation as cause. Use the required report content and record the preliminary completion against the actual clock. Interim measures address recurrence while the full investigation proceeds. Assign and verify the appropriate response under qualified direction; completing a report cannot make an unresolved hazard acceptable until the final analysis is ready.
- Develop the full investigation with supported causes. Analyze the facts and underlying factors with the appropriate people, retaining changed findings transparently. Use the current WorkSafeBC form or another format containing all required information. Keep evidence, conclusions and recommended actions distinct. The full report’s required submission needs an actual receiving record; saving a draft in a company folder does not establish submission or satisfy its deadline.
- Distribute reports and check corrective actions. Follow the applicable committee, worker-representative or workplace-posting requirements and protect personal information appropriately. Record final corrective actions, responsible people, completion and follow-up through the required process. Keep incomplete actions visible after the full investigation is submitted. A deadline reminder supports the process; it does not grant an extension, replace missing content or prove that the implemented response addresses the investigated conditions.
Common mistakes
- Treating the diary entry as every required report.
- Waiting for the full analysis before necessary interim action.
- Calling a saved draft a submitted full report.
- Closing corrective actions when the investigation is submitted.

Check your understanding
The full report was submitted on time, but two required corrective actions remain incomplete. Is the investigation response finished?
