What Manitoba requires
- When a serious incident occurs, the employer notifies the Workplace Safety and Health Branch immediately by the fastest means available, giving the name and address of each person involved, of the employer (and of any other employer of a person involved), and of each witness, the date, time and location, and the apparent cause and circumstances; inaccurate or incomplete information is corrected immediatelyWorkplace Safety and Health Regulation, M.R. 217/2006, s. 2.7
- A serious incident is one in which a worker is killed or suffers an injury from electrical contact, unconsciousness from a concussion, a fracture of the skull, spine, pelvis, arm, leg, hand or foot, an amputation of an arm, leg, hand, foot, finger or toe, third-degree burns, permanent or temporary loss of sight, a cut or laceration needing medical treatment at a hospital, or asphyxiation or poisoning; or one involving a structural collapse or failure (building, structure, crane, hoist, lift, temporary support or excavation), an explosion, fire or flood, an uncontrolled spill or escape of a hazardous substance, or the failure of an atmosphere-supplying respiratorM.R. 217/2006, s. 2.6
- Except to free a trapped person or avoid an additional hazard, and subject to a safety and health officer's directive, nothing involved in a serious incident is altered or moved until at least 24 hours after the notice to the branchM.R. 217/2006, s. 2.8
- As soon as reasonably practicable, the employer has each serious incident investigated, as well as any accident or dangerous occurrence that injures a person who then needs medical treatment or that could have caused a serious incident; the investigation is done by the committee co-chairpersons or their designates, or the employer and the workplace representative, or, where there is neither, the employer with a worker not associated with managementM.R. 217/2006, s. 2.9 (1), (2)
- After the investigation, the employer, consulting the co-chairpersons, representative or worker, prepares a written report with the name of anyone injured or killed; the date, time and place; a description; any graphics, photographs or other evidence that may help determine the cause; an explanation of the cause, including factors or events that indirectly contributed; any immediate corrective action taken; and any long-term action to prevent a similar occurrence, or the reasons for no actionM.R. 217/2006, s. 2.9 (3)
- Records required by the regulation are kept for the period it prescribes or, where none is prescribed, for five years after they are made or come into the employer's possessionM.R. 217/2006, s. 2.10
- Every workplace safety and health program includes a procedure for investigating incidents and dangerous occurrences and a procedure for worker participation in their investigationThe Workplace Safety and Health Act, C.C.S.M. c. W210, s. 7.4 (5) (i), (j)
Serious incidents: notify the branch immediately
A serious incident includes a death and injuries such as electrical contact, a concussion with unconsciousness, a fractured skull, spine, pelvis, arm, leg, hand or foot, any amputation including a finger or toe, third-degree burns, loss of sight, a cut treated at a hospital, and asphyxiation or poisoning. It also covers collapses, explosions, fires, floods, uncontrolled hazardous spills and air-supplied respirator failures.
The employer notifies the branch at once by the fastest means available, with the names and addresses of those involved, the employer (and any other employer), and the witnesses, plus when and where it happened and its apparent cause. Nothing involved is moved for at least 24 hours after that notice, except to free someone or prevent another hazard.
Who investigates
Serious incidents, injuries that need medical treatment, and dangerous occurrences that could have been serious are investigated as soon as reasonably practicable: by the committee co-chairpersons, or the employer and the worker representative, or the employer with a worker outside management where there is neither. The employer's safety and health program includes these procedures.
The written report
The employer writes the report in consultation with the investigators. It names anyone injured or killed, gives the date, time and place and a description, attaches photographs, drawings or other evidence, explains the cause including indirect factors, and lists the immediate corrective action and the long-term action to prevent a repeat, or why there will be none. Records are kept for five years unless the regulation sets another period.
From notes to a Manitoba incident report
Note what happened, who saw it and how to reach them, and what you changed right away and for the long term. ReportDraft sets the incident category, records the investigators and when the branch was notified, keeps witness addresses, attaches your photos, and separates immediate from long-term corrective actions.
Common mistakes
- Treating a finger amputation or a hospital-treated cut as minor; both are serious incidents in Manitoba.
- Moving equipment before 24 hours have passed since notifying the branch.
- Investigating without the committee co-chairs, the representative or a non-management worker.
- Stopping at the direct cause without the factors that indirectly contributed.
- Listing immediate fixes but no long-term action, or no reasons for taking none.
