Critical incident

Also known as: CISD · CISM · PFA

A critical incident is a workplace event with the potential to cause significant psychological distress — fatality, serious injury witnessed by colleagues, armed robbery, assault, near-miss to self or co-worker, large-scale evacuation. The PCBU's response triggers Critical Incident Stress Management (CISM) processes including EAP activation, structured debrief and return-to-work follow-up.

Legal context

Critical-incident response is the SDA s47C / ISO 45003-aligned process by which a PCBU manages the psychosocial aftermath of a significant event. The accepted models include CISD (Critical Incident Stress Debriefing), CISM (Critical Incident Stress Management), PFA (Psychological First Aid), structured Defusing and Informal Conversation. The choice depends on incident severity, time elapsed and worker preference. The PCBU's duty is not to provide therapy — it is to activate EAP, assign peer support, run a structured debrief, monitor for delayed-onset trauma, and coordinate with the return-to-work pathway. Failure to manage critical-incident response is now treated as a psychosocial-hazard control failure under the Model Code 2022.
