THE PLATFORM

One platform, every point of contact

A dashboard for site management, HSE and the gatehouse, an app for security officers, an app for your workforce, and kiosks for inductions and stores — all reading from the same site record.

Access & attendance
QR clock-in at the gate, checked on the server against the person, their phone and the site boundary. Vehicles, drivers, visitors and contractors signed in and out, and a live headcount.
01 — GATEHOUSE
Incidents, signed off by HSE
A full incident report — people involved and injuries, witnesses, RIDDOR and COMAH flags, root cause, corrective actions and photo evidence. Nothing closes until HSE signs it off.
02 — HSE
Muster & emergency response
One tap declares an emergency, freezes the roll call at that moment and groups everyone by duty — fire marshals, first aiders, each role — live on every dashboard and security phone.
03 — ASSEMBLY POINT
Security patrols
QR tags placed around the site, scanned in route order. The first tag starts the patrol, the last one ends it, missed tags are recorded, and anything wrong goes straight into an incident.
04 — PERIMETER
Inductions that can’t be skipped
Contractor, visitor and driver inductions on a kiosk: a video that can’t be paused or skipped, site rules in the person’s own language, then everyone present signs and it prints.
05 — KIOSK
Stores self-checkout
PPE, dry chemical and wet chemical stores on one kiosk. Every item scanned out against a named operative, with live logs per store and a catalogue your site admin controls.
06 — STORES
Parcels & notices
Security books a parcel in and the person is told on their phone. Notices go to the whole site, a role or one person, with read receipts.
07 — WORKFORCE
Keys, roles & accountability
Every person signs in with their own key; site admins, HSE, managers and officers also get a dashboard login. Keys are revoked in seconds, and every action is written to the audit log.
08 — CONTROL
REGULATED SITES

Built around how COMAH sites actually run

Centrion started on the ground at a working chemical resins site, so the workflows match how contractors, drivers and shift patterns move in practice — not a generic HR tool adapted after the fact.

Inductions for contractors, visitors and drivers — a video that can’t be skipped, then site rules, PPE and the COMAH notice in their own language, signed and printed.
Every incident signed off by HSE — RIDDOR and COMAH flags, photo evidence and corrective actions with owners and due dates.
Printed records on your letterhead — muster rolls, induction records and patrol logs, each with a record number and timestamp.
Chemical and PPE stores, patrols and an audit log — who went where, took what and did what, and when, in one place.

QUESTIONS

Site sign-in and safety, answered

What is Centrion?

Centrion is a site access and safety platform for industrial sites. It runs gate sign-in, QR clock-in, contractor, visitor and driver inductions, security patrols, incident reports, stores and emergency muster from one shared site record, with a dashboard, a Security app, a People app and kiosks.

Is Centrion suitable for COMAH sites?

Yes. Centrion started at a working COMAH chemical site. Inductions include the COMAH notice, incidents carry RIDDOR and COMAH flags and are signed off by HSE, and the muster roll is frozen the moment an emergency is declared.

How do visitors, contractors and drivers sign in?

Security signs them in at the gate on the dashboard or the Security app, with their company, host, badge and vehicle. Returning people are recognised, trucks are tracked separately from drivers, and anyone banned from site can't be signed in.

Can inductions be given in other languages?

Yes. Kiosk inductions have site rules, PPE and the COMAH notice in 24 languages, with a read-aloud option, a video that can't be skipped, and a signature that is kept with the record.

How does the emergency muster work?

One tap declares an emergency on any dashboard or security phone. Everyone on site at that moment goes onto the roll call, grouped by duty, and is marked safe or missing live on every device. Nobody can be signed in until it is stood down.

Do workers need to install an app?

No app store is needed. The People app and Security app open in the phone's browser and can be added to the home screen. Staff clock in by scanning the gate QR code, checked against the site boundary.

Where is the data stored and for how long?

In the UK (London). Records are kept for 13 months on a rolling basis, and site admins are warned before each monthly deletion so they can download anything they need to keep.
