Alone in a chamber or substation
An engineer works down a chamber or inside a remote substation — around live systems, in a confined space, with no colleague within earshot if something goes wrong.
Utilities & Field Teams
Water, gas, power and telecoms engineers, meter readers and field technicians spend their days at remote sites, down chambers and out on rural rounds — often where phone signal is patchy and the nearest colleague is miles away. Not A Lone Worker keeps track of every job so a missed check-in in the middle of nowhere gets noticed straight away.
Where it goes wrong
Distance, poor signal and out-of-hours callouts are what make field engineering a lone-worker risk. These are the situations UK utilities teams plan for.
An engineer works down a chamber or inside a remote substation — around live systems, in a confined space, with no colleague within earshot if something goes wrong.
A meter reader or field tech covers a scattered rural round where the phone drops to no bars for long stretches — so no one can easily reach them, or know if they’ve moved on.
A technician is called out on their own to a fault in the middle of the night. The depot’s closed, the office has gone home, and no one is actively expecting them to report back.
A field worker slips, is hurt, or their van breaks down on a remote stretch. They may be able to raise the alarm — or they may need the system to notice for them.
How NALW fits
Each of those maps to something the platform already does — and because it fails safe, patchy signal counts against being safe, not for it.
Alone in a chamber or substation: a check-in timed for when a job should be done means an engineer who doesn’t resurface is quickly missed. A grace window and nudge come first, then escalation — so a quiet confined space doesn’t stay quiet unnoticed.
A rural round with no signal: the system treats no clear “I’m safe” as a reason to worry, not to assume the best. If a check can’t be answered because a worker’s out of coverage and stays out, it escalates rather than quietly ignoring it.
An overnight fault callout: the technician clocks on with START and an expected finish. Run past it with no DONE and it flags overdue and raises the escalation ladder on its own — no one has to be watching the depot phone.
An injury miles from anywhere: a one-tap SOS — or a texted HELP — sends an alert with the worker’s last-known location, so a mate or manager knows the last spot the engineer confirmed themselves, even out on a remote patch.
Start here
Checks timed around each job by SMS, email or the no-install link — and they fail safe when a reply can’t get through.

See panic & SOSA day in the life
Picture a field team spread across a regional patch. Each engineer texts START with an expected finish as they reach a job, and the coordinator can see on the Locations map where each one last checked in safe — nothing more, no live trail down the roads.
One engineer heads down a chamber in a dead spot and the job overruns. The shift flags overdue, the check-in can’t be answered from underground, and Zoe’s call goes unanswered — so the escalation ladder reaches a supervisor with the engineer’s last-known location, instead of the silence being put down to “no signal” and left until morning.
This is an illustration of how the pieces fit together, not a real client story — but every step in it is something the platform does today.
