This SWMS covers the management of physical assault, verbal threats, and unpredictable behaviour from patients, relatives, and visitors in Australian hospitals, mental health units, emergency departments, aged-care facilities, community health centres, and correctional health settings. It is written for registered and enrolled nurses, personal care assistants, mental health clinicians, emergency department staff, security officers, social workers, and any worker whose duties involve direct patient or public contact in a clinical environment. Every task has been authored against the Model WHS Regulations Part 3.1 (Managing Risks), the Safe Work Australia — Work-Related Violence Prevention guidance (2021), and the therapeutic restraint provisions of the applicable state Mental Health Acts.
Work-related violence is the third-highest cause of serious workers' compensation claims in the Australian healthcare sector, behind body stressing and falls. Safe Work Australia data consistently shows that healthcare and social assistance workers experience the highest rate of occupational violence of any industry, with emergency department nurses recording the highest exposure frequency. The risks are compounded by inadequate staffing ratios during peak periods, solo community visits, the clinical imperative to not withdraw from a patient in medical need, and the legal and ethical constraints on restraint and seclusion. This SWMS applies a prevention-first hierarchy — environmental design, early behavioural detection, de-escalation — with escalation procedures that comply with state Mental Health Act provisions on restrictive practices and with the National Mental Health Consumer and Carer Forum standards on restraint minimisation.
Hazards identified
10 hazards covered, sorted by priority.
Soft-tissue injury, fracture, or laceration causing immediate harm; psychological trauma, hypervigilance, and PTSD from repeated assault exposure causing chronic psychological injury and workforce attrition.
Head injury, eye injury, or laceration from objects thrown by an acutely agitated or psychotic patient; risk is highest in confined spaces where workers cannot achieve safe exit distance.
Acute stress response, anxiety disorder, PTSD, and burnout from chronic exposure to verbal threats and degrading behaviour; psychological injury claims are increasing proportionally with physical injury claims in healthcare.
Worker left in an unsafe situation without backup if duress alarm is non-functional, not worn, or response team is unavailable; escalation to serious assault if support does not arrive promptly.
No safe exit route if patient blocks the door; no witness or immediate backup; highest risk for solo nursing assessments, medication rounds, and personal care tasks in closed rooms.
Musculoskeletal injury to worker during physical restraint attempts; patient injury, positional asphyxia, or cardiac event if restraint technique is incorrect or prolonged; litigation and regulatory investigation.
Worker assaulted by patient, household member, or dog in a private home with no security infrastructure, no witness, and delayed emergency response; highest risk for after-hours visits to new or high-risk clients.
Relatives or visitors join an aggressive patient in confronting staff; gang-type assault in waiting areas or car parks; highest risk in emergency departments during extended wait times.
Secondary psychological injury from insufficient post-incident support; workers who return to work without debriefing and counselling are at higher risk of PTSD, sick leave, and resignation.
Under-trained staff unable to apply Threat Assessment Triage or verbal de-escalation techniques; situation escalates to requiring physical restraint that could have been avoided with earlier intervention.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Environmental design — all patient assessment rooms equipped with two exit routes or a door that opens outward; nurse stations with sight lines to patient areas; duress alarm activation points at patient bedsides, nurse stations, and staff-only exits; CCTV coverage of all public waiting areas.
- 2Behavioural observation and Threat Assessment Triage (TAT) — all clinical staff trained to recognise early warning signs of escalating agitation (pacing, clenching, verbal escalation, dissociation); TAT score documented in patient record; any patient scoring high risk flagged to charge nurse and security.
- 3Verbal de-escalation training — mandatory for all staff with direct patient contact; covers calm tone, non-threatening posture, active listening, redirection, and when to exit. Refreshed annually. Training records retained.
- 4Duress alarm system — personal duress devices worn by all staff in high-risk areas (ED, mental health, acute wards); devices tested monthly; response team response time target 90 seconds; device battery-low alert monitored by security operations.
- 5Lone-worker protection for community staff — GPS-enabled check-in protocol before entering any home visit; buddy system or remote monitoring for after-hours visits to clients flagged as violence risk; escalation procedure if worker misses check-in.
- 6Therapeutic restraint — only authorised under state Mental Health Act provisions, as a last resort, following failed de-escalation, documented in the patient record, and reviewed by the treating clinician within 15 minutes; restrictive practice is prohibited as a response to behaviour that is not an immediate safety risk.
- 7Break Away self-protection techniques — all staff in high-risk areas trained in safe release from grabs (wrist, collar, hair) using minimum-force techniques that do not escalate the situation; training conducted by accredited provider and refreshed annually.
- 8Security team response protocol — security responds to all duress alarms and visible altercations within 90 seconds; security staff trained in verbal de-escalation and physical intervention as a last resort; radio communication with charge nurse for all responses.
- 9Post-incident support — mandatory structured debriefing within 4 hours of any assault or near-miss; Employee Assistance Program (EAP) referral offered to all involved workers; incident report completed within 24 hours; WHS investigation commenced within 48 hours.
- 10Visitor management — all visitors screened at entry points during high-risk periods; CCTV in public areas; security authorised to request removal of threatening visitors from the premises; police called for any criminal assault.

Worked example
At 14:30 in a metropolitan Sydney emergency department a triage nurse observes a male patient (waiting 3 hours, presenting with acute psychosis) begin pacing, raising his voice, and making threatening gestures toward the triage desk. She activates the duress alarm on her wrist device and moves to an open area with two exit routes. A second nurse joins and they both adopt a non-threatening side-on posture at two metres distance. The charge nurse initiates verbal de-escalation: calm tone, uses the patient's name, acknowledges his frustration, and offers a quiet room. The patient does not respond and begins throwing a chair. Security arrives within 75 seconds. With a four-person response, verbal de-escalation continues for 90 seconds until the patient sits. A treating psychiatrist is called; medication is offered and accepted. The patient is moved to a mental health assessment room. Post-incident, all five involved staff participate in a structured 30-minute debriefing with the clinical nurse manager; EAP contact details are distributed; an incident report is completed within two hours.

Frequently asked questions
Are workers legally required to submit to a patient assault without defending themselves?
No. Workers have a legal right to self-defence under common law — they may use reasonable force to protect themselves from assault. This SWMS provides trained Break Away techniques as the preferred self-protection method because they minimise risk of injury to both parties. Workers should never feel legally compelled to remain in a physically dangerous situation without using reasonable self-protection measures. The clinical imperative to care for a patient does not override a worker's right to personal safety.
What are the legal boundaries on therapeutic restraint?
Restraint may only be used under state Mental Health Act provisions as a last resort when a patient presents an imminent risk of serious harm to themselves or others, after verbal de-escalation has failed. It must be the minimum necessary, for the minimum duration, documented immediately in the patient record, and reviewed by the treating clinician within the statutory timeframe (typically 15 minutes). Restraint used as a management strategy for challenging behaviour — rather than immediate safety risk — is prohibited and may constitute assault.
What do we do if a community worker does not make a scheduled check-in call?
If a community worker misses a scheduled check-in, the supervisor initiates the escalation protocol: attempt contact by phone (2 attempts, 5 minutes apart), then contact the client's address by phone, then dispatch a welfare check by a second worker or request a police welfare check. Time from missed check-in to police welfare check request should not exceed 30 minutes for high-risk visits. The threshold is reduced to 15 minutes if the visit was to a client with a documented history of violence.
Is mandatory debriefing after an assault a WHS legal obligation?
The model WHS framework requires PCBUs to manage psychological risks at work, which includes post-incident psychological support. While mandatory structured debriefing is not specified in the WHS Regulation by name, failing to provide post-incident support constitutes a failure to manage a foreseeable psychological health risk and may support a negligence claim. Safe Work Australia's work-related violence guidance explicitly recommends mandatory post-incident debriefing as best practice.
