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 Safety Detection Points and safety 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 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
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.
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.

Proof
Sites already accounted for.
From 22-minute paper musters to a live count in under 3.
“For the first time we can prove, not just claim, that everyone was accounted for.”
Graded-area control without slowing the gowning flow.
“We got the control we needed without a single extra turnstile.”
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.”
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 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 access & zone control 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 access & zone control 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.
