- An incident that had a likelihood of causing serious injury or illness, where corrective action may be needed to prevent a recurrence (a potentially serious incident), is investigated and reported the same way; the report is submitted online after the investigation is complete, and the scene does not have to be securedOHS Act, s. 33 (5) · Alberta.ca, Report potentially serious incidents
- Unless a Director, OHS officer or police officer directs otherwise, no one disturbs or works at the scene of a reportable injury, illness or incident, or alters, moves or removes related equipment, documents or information, except to attend to the ill, injured or killed, prevent further harm, or protect endangered propertyOHS Act, s. 33 (9)

Serious injuries and incidents: call OHS as soon as possible
The prime contractor, or the employer when there is none, calls the OHS Contact Centre at 1-866-415-8690 as soon as possible when a worker dies, when a worker has been or will be admitted to hospital (treatment in an emergency room or urgent care does not count), after an unplanned explosion, fire or flood that caused or could cause serious harm, when a crane, derrick or hoist collapses or upsets, or when part of a building or structure fails.
The scene stays as it is, equipment and documents included, until an OHS officer, Director or police officer says otherwise, except to help the injured, prevent more harm or protect property.
Potentially serious incidents
A near miss that was likely to cause serious injury or illness, and may need corrective action, is a potentially serious incident. It is investigated the same way, and its report is submitted online once the investigation is complete. The scene does not have to be secured.
The investigation report
The investigation report outlines the circumstances and the corrective action taken to prevent a recurrence. It goes to a Director and to the joint health and safety committee or representative, or is made available to workers when there is neither, and is handed to an OHS officer on demand. It is kept for at least 2 years, and it cannot be used as evidence in a trial or inquiry about the incident, except for perjury.
From notes to an Alberta incident report
Note what happened, who was involved and what you changed. ReportDraft marks whether the incident is serious, potentially serious or internal only, names the prime contractor and the investigators, records when OHS was called, and lists every step to prevent a recurrence as a corrective action.
Common mistakes
- Treating an emergency room visit as a hospital admission, or missing a real admission.
- Not calling the OHS Contact Centre right away after a serious incident.
- Cleaning up the scene before an officer gives permission.
- Skipping the investigation report for a near miss that could have seriously injured someone.
- Not giving the report to the joint committee or health and safety representative.
