What are some examples of critical incidents in the workplace?

A traumatic incident is anything that was unlikely or unexpected, not preventable or uncontrollable.
This might include:

• Experiencing or witnessing a serious accident, either during, outside of, or on the way to, work
• Being verbally, physically or sexually assaulted
• Other acts of violence (e.g. armed robbery)
• Being threatened with physical harm
• An unexpected death or suicide
• Vicarious trauma (e.g., hearing or witnessing traumatic events)
• Natural disasters such as bushfires or floods
