Critical Injuries are defined in the Ontario Occupational Health and Safety Act (OHSA).
McMaster departments should contact EOHSS (x24352) for assistance and clarification.
In the Event of a Critical Injury
The OHSA defines how all organizations must react in the event of a critical injury. At McMaster, the EOHSS department is delegated the responsibility of ensuring that all legally binding reporting requirements are fulfilled.
In the event of a critical injury at McMaster, workers must:
- render immediate emergency assistance
- notify the workplace supervisor
- ensure the scene remains undisturbed until investigated by a Ministry inspector
The supervisor then:
- immediately notifies EOHSS
- ensures the scene remains undisturbed until investigated by a Ministry inspector
- completes an incident report
- immediately notifies the Ontario Ministry of Labour (MOL)
- immediately notifies the Joint Health and Safety Committee (JHSC) and employee’s union
- issues a written report to the MOL within 48 hours
The scene of the critical injury is then subject to an investigation.
Critical Injury Investigation
The scene of a critical injury must be inspected by an MOL inspector, as well as by a worker representative from the JHSC.
