Lone Worker Safety · COMAH Sites
Lone Worker Safety for comah sites sites.
Welfare monitoring that raises an alert when a worker stops moving or misses a check-in — before a bad day becomes a fatality. Purpose-built for the regulatory and operational realities of comah sites.
The Salvus Network watches for the tell-tale signs of a lone-worker incident: someone who has stopped moving in a restricted area, missed a check-in window, or lingered somewhere they shouldn't. When a welfare condition is met, operators get an alert with the worker's last-read location so help can be dispatched immediately. It closes the gap between an incident and the response, which is where lone-worker outcomes are won or lost. For comah sites operators, this means on a Control of Major Accident Hazards (COMAH) establishment, the difference between a controlled response and a fatality is measured in minutes — and the difference between passing and failing an intervention is a defensible record. Paper roll-calls, T-card boards and radio round-robins were never designed for a toxic release, a vapour-cloud explosion or a spreading fire, and they leave you with a head count you cannot prove. The Salvus Network reads every worker's Tag at Anchors on gates, muster points and restricted-zone thresholds, turning each read into a live SAFE / EVACUATING / MISSING picture and a timestamped record that writes itself. When the Competent Authority asks how you know everyone was clear of the hazard zone, you show them, rather than tell them.
What you get
Lone Worker Safety on a comah sites site.
Welfare alerts
Automatic alerts when a worker stops moving or misses a check-in window.
Restricted-zone watch
Know instantly when a lone worker enters an area they shouldn't be in.
Last-read dispatch
Every alert carries the worker's last-known zone so response goes straight there.
Escalation ladder
Unacknowledged welfare checks escalate automatically to the next responder.
Regulatory alignment
Evidence for the audit trail.
COMAH 2015 places two duties at the centre of personnel accountability. Regulation 5 requires a Major Accident Prevention Policy (MAPP) and, for upper-tier sites, a full safety report demonstrating that all measures necessary have been taken. Regulation 7 requires adequate emergency plans — internal and, via the local authority, external — that can be put into effect without delay. In practice, both hinge on being able to account for people quickly and accurately during a loss of containment. The Salvus Network provides the live head count, the last-seen location for anyone still inside a hazard zone, and the automatic time-to-safe record that evidences an effective emergency plan. It also supports the wider regime around a major-hazard site: DSEAR and the ATEX zoning that governs work in explosive atmospheres, HSG191 guidance on emergency response and, where relevant, the security expectations for sites holding scheduled substances. Every drill and real activation is logged, giving you the audit trail the Competent Authority and your own assurance teams expect.

Proof
Sites already accounted for.
An assured, time-stamped muster the Competent Authority could see.
“We could show the regulator a timed, accurate muster instead of talking them through a plan.”
Clinical hours returned and staff duress answered in seconds.
“Our staff feel safer, and we finally know where the pumps are.”
Lone housekeepers protected and evacuations verified.
“Our housekeeping teams know help is one press away, and we can prove our evacuation works.”
Frequently asked questions
Is Lone Worker Safety suitable for comah sites sites?+
Yes. The Salvus Network is a complete, off-the-shelf solution built for major-hazard environments and deployed across comah sites operations — Anchors and Tags give a live, auditable picture of every worker, asset and zone.
How does Salvus support compliance for comah sites operators?+
The platform produces a live, timestamped muster record and auditable time-on-site and access logs that evidence personnel accountability under COMAH, DSEAR and CDM regimes.
Can we see lone worker safety running before we commit?+
Yes — a live evacuation demo runs on your own site map within 24 hours, and you can see the operator console working in the first meeting.
