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 detects every worker's safety tag at Safety Detection Points 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.

On the ground

How comah sites sites put it to work.

Loss-of-containment muster

When a release is detected, marshals see a live SAFE / EVACUATING / MISSING rollup within seconds and know exactly who is still inside the affected zone, so rescue effort is directed rather than guessed.

Shelter-in-place accountability

For a toxic release where evacuation is the wrong call, track who has reached a designated refuge and who has not, without anyone leaving cover to be counted.

Restricted-zone and permit control

Gate ATEX-zoned and high-hazard areas to authorised, inducted workers only, with live occupancy against permitted limits and an immediate breach alert.

Assured drills and CA evidence

Every exercise is captured with per-muster rosters, timings and a time-to-safe figure, the documented, demonstrable emergency plan the Competent Authority expects to see.

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.

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 upper- and lower-tier COMAH establishments. Safety Detection Points and safety tags give a live, auditable picture of where people were last detected, without turnstiles or manual sign-in.

How does Salvus support compliance for comah sites operators?+

It evidences the two duties at the centre of COMAH 2015: Regulation 5 (major-accident prevention policy and, for upper-tier sites, the safety report) and Regulation 7 (emergency planning), with a live head count, last-seen location and automatic time-to-safe record, alongside DSEAR, ATEX and HSG191.

What does lone worker safety address on a comah sites site?+

On a COMAH establishment the difference between passing and failing an intervention is a defensible record. The platform turns every tag read into a live SAFE / EVACUATING / MISSING picture and a timestamped time-to-safe record.

Can we see lone worker safety running before we commit?+

Yes, a guided live walk-through shows the platform in action, and you can see the operator console working in the first meeting.
