When a Serious Incident Occurs

The scene of a serious incident must not be disturbed until WSH has been notified and has released the scene. Where WSH will be conducting an investigation, WSH may require the scene to be persevered for at least 24 hours after WSH has been notified.

In order to preserve the scene, no equipment or materials that were involved in an incident may be altered or moved, unless it is necessary to free an injured or trapped person, to avoid creating additional hazards, or to provide immediate/critical care.

If you are unsure whether an incident is reportable under the requirements of the Workplace Safety and Health Regulation, contact WSH for clarification.

Whether or not an incident or other dangerous occurrence is required to be reported to WSH, the employer must conduct an internal investigation with the workplace safety and health committee co-chairs (or their designates). This investigation is to assist in determining the cause(s) of the incident so that measures can be put in place to reduce the likelihood that a similar incident will occur again.

When reporting an incident to WSH, please have the following information ready:

  • the name and address of each person involved in the incident;
  • the name and address of the employer, or any other employers involved;
  • the name and address of each person who witnessed the incident;
  • the date, time and location of the incident;
  • the apparent cause of the incident and the circumstances that gave rise to it

If you realize that any of the above information you provided was incorrect or incomplete, you must immediately contact WSH again with the new information.
