Occupational violence in healthcare.

Healthcare is one of the most exposed sectors for occupational violence and aggression. This is what OVA means, how the Code Grey and Code Black responses work, and where a staff duress alarm fits within them.

The terms

Code Grey and Code Black

Australian hospitals use emergency colour codes (aligned to the Australian Standard AS 4083). Two relate to personal threats:

Code Grey

In the Victorian Department of Health's Code Grey Standards, Code Grey is "an organisation-level response to actual or potential violent, aggressive, abusive or threatening behaviour, exhibited by patients or visitors, towards others or themselves, which creates a risk to health and safety." In short: an unarmed aggression response.

Code Black

Code Black is treated as a separate, escalated response - for an armed or personal threat involving a weapon. The Victorian standards require a Code Grey alert to be separate from Code Black.

A caveat that matters: the labels are not applied identically across states. NSW health services, for example, commonly use "Code Black" for the aggression/personal-threat response that Victoria calls "Code Grey." Always follow your own health service's standard.

This is general information, not legal or clinical advice. The definitions above are drawn from the Victorian Department of Health's Code Grey and Code Black resources; terminology and standards vary by state and health service - follow your own organisation's policy.

The gap

Where the trigger fails

The weak point in many aggression-response systems is the trigger, not the response plan. Wall-mounted duress buttons assume the incident happens near a wall. Overhead announcements assume a worker can reach a phone and speak. Neither helps a clinician pinned in a bed bay, a nurse in a car park, or a community health worker in a client's home.

A wearable staff duress alarm closes that gap: a worker can raise the alarm silently, from anywhere, with their exact location attached - effectively calling a Code Grey from wherever they are. On camera-equipped devices, the responder sees the situation as well as the location. That's the difference between a response that goes to the right corridor and one that goes to the front desk.

Beyond hospitals, the same pattern applies wherever aggression response is formalised - emergency departments, mental health units, corrections, and increasingly community and in-home care, where the responder is a monitored centre rather than on-site security.

Questions

Common questions

What is occupational violence and aggression (OVA)?

OVA is any incident where a worker is abused, threatened or assaulted in circumstances arising from their work - from verbal abuse and threats through to physical assault. In healthcare it commonly comes from patients, their families, or the public, and it is treated as a foreseeable workplace hazard employers must control.

What's the difference between Code Grey and Code Black?

In Victoria, Code Grey is the response to unarmed aggression or threatening behaviour; Code Black is the separate, escalated response to an armed or weapon-based threat. Note that other states apply the labels differently - NSW commonly uses Code Black for aggression responses - so follow your own health service's standard.

How do staff duress alarms fit a Code Grey response?

A wearable duress alarm lets a worker raise the alarm silently and from anywhere, with their exact location - in practice, calling a Code Grey from wherever the incident happens, rather than depending on reaching a wall button or a phone. It's the trigger layer of the response, not a replacement for the response plan.
