Definition

What is staff & worker safety location?

Canonical definition

Staff and worker safety location is the real-time monitoring of people and their safety alerts within a facility using wireless infrastructure. It enables security and operations teams to locate a worker instantly when they raise a duress alarm, fall, or fail to check in - and to account for everyone during an evacuation. Pole Star delivers it on your existing BLE and Wi-Fi network.

What

It locates people and their alerts in real time - duress, man-down and mustering - on a live map.

Who

It protects nurses, lone workers and site teams in hospitals, industrial plants, transport and maritime environments.

Why now

Violence against staff and lone-worker risk are rising, and response time is the difference between a scare and a serious incident.

How

Pole Star reads BLE badges and phones on existing infrastructure and turns an alert into a name, a location and an instant dispatch.

Three ways Pole Star protects your teams

Staff duress

A nurse or worker presses their badge or phone - you get their identity and exact location, and dispatch help in seconds.

Lone worker protection

Badges and phones detect workers in isolated or restricted areas, with automatic man-down and fall detection.

CO₂ mustering

Counts workers in machinery and engine rooms and confirms everyone is out before CO₂ fire suppression is released.


The business challenge: when help is too slow, or in the wrong place

Violence against staff and risk to lone workers are rising - and when an incident happens, the alarm alone is not enough. Without real-time location, responders know something is wrong but not who, or exactly where, wasting the minutes that matter most.

Nurses face assaults in wards and corridors; technicians work alone in plant rooms, tunnels and restricted areas where a fall can go unnoticed; and in machinery spaces, you cannot release CO2 fire suppression until every worker is confirmed out. Each of these is a location problem before it is a response problem.

The consequences are serious: injured staff, failed duty-of-care, regulatory exposure, and teams who no longer feel safe at work. Response time is the metric that decides the outcome.

Business outcomes

What changes when every alert has a location

Concrete outcomes safety and operations teams see with real-time worker-safety location.

01

Faster emergency response

An alert arrives with a name and an exact location, so help reaches the right place immediately.

02

Staff who feel protected

Confidence rises when teams know a single press brings located, verified help.

03

Lone workers never invisible

Man-down and no-check-in alerts catch incidents even when no one is around to see them.

04

Safe, confident mustering

Confirm every worker is clear of a machinery space before CO2 suppression is released.

05

Cleaner escalation

Alerts route to the right team with context, cutting confusion and false-alarm fatigue.

06

Auditable duty-of-care

Every alert, location and response is logged - evidence for compliance and continuous improvement.

Common pain points

Sound familiar?

What teams say before they put real-time location behind their safety alerts.

By the time security arrives, they don't know which room I'm in.

A raised alarm without a location wastes the minutes that decide how an incident ends.

Our panic buttons are fixed to the wall - useless if I'm attacked in a corridor.

Fixed alarms don't cover the places where staff are actually at risk.

Technicians work alone in plant rooms with no way to call for help if they fall.

A lone-worker injury can go unnoticed for far too long.

We can't release CO2 until we're sure everyone's out - and we're never sure.

Uncertainty over headcount delays fire suppression and puts lives at risk.

Every alert is a blind alarm - we know something happened, not where.

Responders run the wrong way while the clock keeps ticking.

We'd need a whole parallel network to add safety - we can't justify that.

Cost and complexity stall protection projects before they start.

How Pole Star solves it

From a single press to a located, verified response

1

Wireless infrastructure

BLE / Wi-Fi

Badges and phones are read by the network you already run - no dedicated parallel system.

2

Badges & mobile

Duress · man-down

A worker presses for help, or a fall is detected automatically - the alert carries their identity.

3

Positioning engine

Real-time location

Pole Star computes exactly where the alert came from, including floor and zone.

4

Alert & escalation

Rules & routing

The right team is notified with context, and escalation follows if no one acknowledges.

5

Response & dashboards

Live map

Responders see the exact location on a live map and move straight to the worker.

6

Auditable outcome

Logged

Every alert, location and response time is recorded for duty-of-care and compliance.

In practice

When a nurse is threatened in a ward, she presses the button on her badge. Within seconds, the security team sees her name and her exact room on a live map, and moves directly to her - no calling out, no guessing which floor. The whole event is logged, from the press to the response.

How the technology works

A badge or a phone, located by the beacons around it

Workers carry a BLE badge or the NAO Mobile app. Beacons and access points around them pick up the signal, Pole Star computes the exact position, and the location appears live on your dashboard - all on existing infrastructure.

CO₂ mustering

Confirm every worker is out before CO₂ is released

CO₂ fire suppression systems in engine rooms and machinery spaces are lethal if anyone remains inside. Pole Star verifies that every worker has evacuated - in real time, automatically - before the suppression system can be released, and alerts responders to the exact location of anyone still inside.

How it works
1
Fire alarm triggers in the engine room

The CO₂ suppression system is armed and a mandatory evacuation is declared. The mustering countdown begins automatically in NAO® Track.

2
Worker positions tracked in real time

BLE badges worn by all workers continuously report their indoor position. NAO® Track monitors who is still inside each CO₂ zone and who has exited.

3
Missing workers located instantly

If anyone remains inside after the evacuation deadline, their exact location is displayed on the dashboard - enabling a targeted rescue before suppression is activated.

4
All clear confirmed - CO₂ authorized

Only when every worker in every zone is confirmed outside does the system display an all-clear - giving the safety officer the certainty needed to authorize CO₂ release.

Lone worker protection

Detect a fall, locate the worker, dispatch help - automatically

Workers in isolated areas - tunnels, plant rooms, rooftops, night shifts - face real risk with no one nearby to help if something goes wrong. Pole Star detects falls, immobility and distress automatically, locates the worker at room level and alerts the nearest responder before a situation becomes critical.

How it works
1
Worker enters an isolated or high-risk area

The worker's BLE badge or smartphone continuously tracks their indoor position via NAO® Mobile. Their zone, floor and status are visible on the NAO® Track dashboard in real time.

2
Fall or immobility detected automatically

The badge or smartphone's accelerometer detects a sudden fall or unexpected loss of movement. An alert is triggered without any action from the worker - critical when they are unable to press a button.

3
Geolocated alert dispatched immediately

The alert reaches the supervision desk and the nearest available responder with the worker's identity and precise indoor location - no radio calls, no guesswork.

4
Responder guided to exact location

NAO® Track shows the worker's last confirmed position on the indoor map. If the worker moves or is moved, their position updates continuously until the alert is closed and logged.

Mobile staff duress

One tap - instant alert with room-level location

When a staff member faces aggression, a medical emergency or any life-threatening situation, the response time depends on how quickly help can reach them. Pole Star delivers a geolocated panic alert to the nearest responder the moment a button is pressed - from the smartphone or badge the worker already carries.

How it works
1
Staff member triggers a duress alert

A single tap on the smartphone app or a press of the badge button fires an immediate alert. No unlock, no navigation - one action is all it takes.

2
Room-level location captured instantly

NAO® Track captures the staff member's precise indoor position at the moment of the alert - room, floor and zone - using the BLE infrastructure already installed in the building.

3
Alert dispatched to the nearest responder

The supervision desk and the closest available colleague receive the alert simultaneously - with the staff member's name, location on the indoor map and time elapsed since trigger.

4
Response tracked, alert closed and logged

Responder arrival and resolution are confirmed on NAO® Track. The entire incident - trigger time, location, responder, resolution - is stored automatically for HR, compliance and post-incident review.

FAQ

Worker safety, answered

How it works · technical
How does staff duress work?

A worker presses a button on their badge or phone. Pole Star reads the signal on your existing network, computes the exact location, and sends an alert carrying the person's identity and position to responders - so help goes straight to the right place.

How does man-down and fall detection work?

Badges and phones carry motion sensors that detect a fall or a prolonged lack of movement. When triggered, the device raises an automatic alert with location - protecting lone workers even when no one is around to call for help.

How accurate is worker-safety location with BLE?

BLE delivers zone or room-level accuracy, on the order of 1-5 meters, including the correct floor - enough for a responder to go straight to the worker. Underground, Pole Star combines LTE and BLE to keep coverage where GNSS is unavailable.

Can staff raise an alert from both a phone and a badge?

Yes. Duress and man-down work from the NAO Mobile app on the phone workers already carry, or from a dedicated BlueSpot safety badge for hands-busy, phone-free or rugged environments. You can mix both across a site.

How does CO2 mustering headcount work?

Pole Star counts the workers inside a machinery or engine space in real time and confirms when it is clear. That confirmation is what allows CO2 fire suppression to be released safely, without risking anyone still inside.

Does it work underground where GPS is unavailable?

Yes. In tunnels, stations and technical areas where GNSS does not reach, Pole Star combines LTE and BLE positioning - the approach deployed across the Grand Paris Express metro lines.

Deployment & infrastructure
Does it require a dedicated safety network?

No. Pole Star runs on your existing BLE-enabled Wi-Fi and Cisco Spaces, so you add worker safety without building a parallel network - the model used at Wantirna across a four-floor facility.

Does it work with our Cisco or HPE Aruba access points?

Yes. Pole Star integrates with Cisco (including Cisco Spaces) and HPE Aruba to read BLE from your existing access points, which keeps deployment fast and avoids new cabling.

How long does deployment take?

Because it uses existing infrastructure, deployments are typically measured in weeks rather than months. Timelines depend on site size, the number of floors and how the network is configured.

What happens if the Wi-Fi goes down?

Live location depends on the network reading the devices, so an outage pauses updates. For environments that demand continuous availability, Pole Star offers on-premise deployment so the engine keeps running locally.

Can it cover multiple floors and buildings?

Yes. Location includes the correct floor, and coverage extends across multi-floor facilities and multi-site estates - proven across a four-floor aged-care facility and four metro lines.

ROI & business case
What is the ROI of a worker-safety system?

The return is faster, better-targeted response, fewer serious incidents, and defensible duty-of-care. Because it reuses existing infrastructure and can also power asset tracking, the same investment covers more than safety alone.

How does it reduce response time?

An alert arrives with identity and exact location, so responders skip the search and go straight to the worker. Removing the "where are they?" step is where most of the time is saved.

Does it help with duty-of-care and compliance?

Yes. Every alert, location and response is logged, giving you an audit trail that demonstrates duty-of-care and supports workplace-violence and lone-worker compliance obligations.

Can we reuse the same system for asset tracking?

Yes. The same BLE infrastructure and platform power asset tracking, so worker safety and equipment location share one deployment.

Who benefits most from worker-safety location?

Hospitals and aged care exposed to violence, industrial sites with lone workers, transport networks working underground, and maritime operations that need mustering all see the clearest benefit.

Privacy, security & data
Is worker location tracked all the time, or only during alerts?

This is configurable. Many deployments surface a worker's location only when they raise a duress alarm or a man-down event fires, rather than tracking continuously - protecting privacy while still enabling fast response.

Is worker location data private and secure?

Yes. Data is access-controlled and role-based, follows enterprise security practices, and can be kept on-premise. Worker safety is configured with privacy in mind and separately from any asset data.

Can location data stay on-premise?

Yes. Pole Star supports fully on-premise deployment, so the location engine and data remain inside your own infrastructure - important for sites with strict data or connectivity constraints.

Does it create an audit trail?

Yes. Every alert, location and response time is recorded, which supports incident review, duty-of-care evidence and continuous improvement of response procedures.

Who can see worker location data?

Access is role-based. Administrators control which teams - typically security and safety responders - can view alerts and locations, so visibility matches each role's responsibilities.
