Operational scenarios
Process safety, enforced at the gate.
Four daily security and safety-compliance pain points for refinery management - and how Chkdin AI addresses each.
Operational scenario 01
Turnaround & Shutdown Access Bottlenecks
The challenge
During major turnarounds, thousands of third-party contract workers enter the site daily. Manual badge and paper Permit-to-Work checks create massive gate congestion, delaying critical maintenance and risking credential sharing.
The Chkdin AI solution
Rapid-deploy barrier gate nodes performing sub-second 1:N facial verification linked to active digital Permit-to-Work databases. Uncertified or un-badged contractors are automatically denied entry at the perimeter line.
Key outcome
Gate clearance speeds increase by 350%, eliminating manual paper checks while ensuring 100% PTW compliance before zone entry.
Operational scenario 02
Unauthorized Intrusion into Volatile Processing Units
The challenge
Contract workers licensed only for general maintenance wandering into hazardous, high-pressure or toxic gas units (hydrocracker, FCC, alkylation) without active hot-work or safety clearance.
The Chkdin AI solution
Thermal camera feeds on localized edge nodes enforce sub-pixel virtual boundaries around restricted units. If an unauthorized person crosses the boundary, local safety consoles are alerted in under 1.0 second.
Key outcome
Immediate prevention of dangerous zone breaches with no reliance on human sentry patrols along perimeter fences.
Operational scenario 03
PPE Compliance Verification at Hazard Gateways
The challenge
Workers entering volatile units without critical PPE - hard hats, flame-retardant suits, safety eyewear, breathing apparatus - creating major OSHA / HSE violations.
The Chkdin AI solution
Dual optical checks at zone entry points simultaneously verify contractor identity and perform multi-point neural PPE detection in a single sub-second scan.
Key outcome
Automated access block for non-compliant personnel, with an audit-ready digital HSE record.
Operational scenario 04
Air-Gapped Operation in High-EMF & Remote Tank Farms
The challenge
Remote tank farms and offshore platforms lack stable internet. Security infrastructure cannot risk cloud downtime or external data leaks.
The Chkdin AI solution
Fully isolated, air-gapped local edge nodes run inference and database matching entirely in volatile RAM buffers. Zero cloud connectivity required.
Key outcome
Uninterrupted 24/7 security and access control during complete network isolation or remote offshore deployment.

Refinery deployments, answered.
Can Chkdin edge nodes be used in ATEX Zone 1 and Zone 2 areas?
Chkdin nodes use weatherproof IP66 anodized aluminum housings designed to integrate into explosion-proof / ATEX-certified field enclosures for Zone 1 and Zone 2 environments.
How does Permit-to-Work verification work at the gate?
Barrier gate nodes perform sub-second 1:N facial verification linked to active digital Permit-to-Work databases. Uncertified or un-badged contractors are automatically denied entry.
Can it check PPE at hazard gateways?
Yes. Dual optical checks verify contractor identity and perform multi-point neural PPE detection - hard hats, flame-retardant suits, eyewear and breathing apparatus - in a single sub-second scan.
Does it work on offshore and remote tank farm sites?
Yes. Nodes run fully air-gapped, with inference and database matching in volatile RAM and no cloud connectivity required.
