Vision
CCTV streams scored by on-edge AI — PPE detection, posture detection, restricted-zone breach, smoke and flame.
Hazards, surfaced before they escalate.
A scenario for HSE teams on a live operating site. PPE compliance, hot-work permits, gas leaks, fall risk, and evacuation flow — wired into the digital twin so every incident has a location, a timestamp, and a chain of responders. The control room sees risk before it becomes an event.

01 — Inside the scenario
What this scenario shows
- Scene 04.1The site, watchedCCTV streams running through AI vision — PPE compliance scored frame by frame, zone by zone, across the twin.
- Scene 04.2The permit lives on the twinHot-work permits and lock-out / tag-out tied to physical assets in the 3D model — open the asset, see the permit, see who signed it.
- Scene 04.3The hazard surfacesGas leaks, smoke, and fall-risk events fire alerts the moment they cross threshold — with the asset, the zone, and the timestamp on the same screen.
- Scene 04.4The team movesAlerts route to the nearest field responder via the mobile app, with the evacuation path overlaid on the twin in real time.
02 — The mechanics
How TwinMs applies
Fig. 04.2
Telemetry
Gas, smoke, CO and temperature sensors on the BACnet / MQTT layer. Edge gateway buffers on connectivity loss.
Fig. 04.3
Permits
Hot-work, confined-space, and lock-out / tag-out permits attached to twin assets — every signature time-stamped and audit-ready.
Fig. 04.4
Routing
Scope-priority routing (sensor → zone → supervisor → command) with mobile dispatch to the nearest responder.
Fig. 04.5
Memory
730-day baselines per zone for false-positive suppression. Every incident, every response, captured for post-event review.
03 — The outcomes
Business value
Risk surfaced in milliseconds — before a near-miss becomes an incident.
Always-on PPE and zone-breach detection across every camera on site.
An auditor-grade trail for every permit, every incident, every response.
Field responders alerted on mobile with the location plotted on the twin.
One shared map across HSE, operations, security, and contractor teams.
