Access & Zone Control · COMAH Sites

Access & Zone Control for comah sites sites.

Real-time zone occupancy and restricted-area control built on the same network of Anchors and Tags. Purpose-built for the regulatory and operational realities of comah sites.

The Salvus Network gives you live occupancy for every zone and enforces who may enter restricted or hazardous areas. Because it works with the site you already have — no turnstiles — you get zone-level awareness without funnelling people through choke points. Operators can see occupancy against permitted limits, spot breaches immediately, and hold an accurate, timestamped record of who was where. 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

Access & Zone Control on a comah sites site.

Live zone occupancy

See how many people are in each zone against permitted limits, in real time.

Restricted-area control

Enforce and monitor access to hazardous or high-security zones.

Breach detection

Immediate alerts when someone enters a zone they aren't authorised for.

Occupancy history

Timestamped records of who was in each zone, for audit and investigation.

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 Access & Zone Control 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 access & zone control 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.
