Lockout/Tagout Verification
Detects whether isolation was completed before work started — locks and tags visible, the right people in the maintenance zone, nobody present during switching, area clear before restart.

What it detects
Isolation is a procedure with a paper record and almost no continuous visual record. Fogsphere adds the second half, as an assurance layer over the permit and the isolation itself.
Visual lock and tag check
Identifies whether padlocks and tags are visibly present at the isolation point before work begins in the associated zone.
Work starting before isolation is complete
Flags activity in the work area that begins ahead of the isolation steps the permit sequence requires.
Personnel present during isolation and switching
Detects people inside switchrooms, isolation zones and equipment areas while switching operations are under way.
Maintenance-zone access and occupancy
Counts who is inside the maintenance work front and compares it against the permit’s expected party.
Restart-area clearance verification
Surfaces whether the equipment area is clear of people, tools and temporary barriers before re-energisation.
Permit-linked visual evidence
Assembles the clips and events associated with a permit into one record, from issue through to closeout.
Isolation-zone and SIMOPS monitoring
Flags conflicting simultaneous operations around an isolated asset, where a second activity encroaches on the isolation zone.
Maintenance panels and cabinets opened
Detects control panels, junction boxes and equipment cabinets opened outside a matching permit window.
Valve and isolation-state confirmation
Reads visible valve positions, indicator lights and isolation-point states remotely, so status can be confirmed without a site walk.
Contractor activity in an isolated area
Identifies contractor presence and activity inside an isolated zone, and whether it matches the permitted scope and window.
Where it applies
Lockout/tagout appears explicitly in the power-generation, chemical, automotive and oil & gas papers — power generation devotes a named opportunity-scope section to it, and chemical ties it directly to permit closeout evidence.
How it works
Edge inference on the cameras you already have
Detection runs on cameras covering the isolation point and the work front. It reports what is visible — a lock, a tag, a person, an open panel — and is designed to support the isolation procedure, never to replace it.
Zones, thresholds and schedules you configure
Map each isolation point to its camera view and its permit type. Set the expected party size, the permitted window and the sequence order, so a correctly executed isolation produces no alerts and a skipped step does.
Every event carries its own evidence
Each detection is logged with a timestamp, the camera and zone it came from, and a short clip. The record can be reviewed, exported or attached to an investigation without trawling through hours of footage.
Feeds the systems already in place
Events surface in Fogsphere Manager and route outward to the VMS, access-control platform, control-room wallboard, ticketing queue or messaging channel operators already watch.
Risk & control objective
The control objective is confidence that the isolation the permit describes is the isolation that actually exists on the plant. The paperwork records intent and sign-off; nothing in the normal process records the physical state of the isolation point over the hours or days the permit stays open.
This is an assurance layer, and the distinction matters more here than almost anywhere else. Fogsphere does not isolate anything, verify electrical dead-state, or authorise work. It reports what the camera can see about locks, tags, panels, valve positions and who is standing where — which is precisely the information that is otherwise only sampled at the moment someone walks past.
The highest-value output is usually the closeout pack. When a permit is queried — internally, by an insurer, or by a regulator — the ask is for evidence that the sequence was followed. A timestamped set of clips against each permit step turns that from a reconstruction exercise into a retrieval.
