- Reads, classifies and answers 40–60 new reports a week by hand. “I read every report. I just read them too late to see the pattern.”

- Opens the pyramid with every report already classified and the rising trend flagged, confirms the serious ones and accepts the actions the agents propose.
One rising precursor, from the depot to a signed safety alert
Lumina Utilities is an electricity and water utility with five sites. On Sunday 11 October 2026, during storm repairs after the wind, a pole ladder kicks out at Ashby Lane, Northgate. By Monday morning it is one of 16. Here is what happens next, screen by screen, in the working solution.

The day opens on the precursor pyramid
Nadia Farouk · Safety advisorNadia covers Network Field Services at the Northgate and Eastmoor depots. Her home screen stacks every report from the last 12 weeks — 916 — into five tiers: 490 unsafe conditions, 233 unsafe acts, 141 low-energy near misses, 38 high energy with a control held and 14 serious potential, up 40 % on the prior 12 weeks. Four reports have arrived since 07:00 and dropped into their tiers in front of her. Beside the pyramid, an alert: ladder work at Northgate Depot.
“Common factor: 11 of 16 used the new 3.8 m pole ladders, batch LD-3800, delivered on 18 Sep without the pole strap. 2 were serious potential.”

Three rising weeks at one depot: 3, 5, then 8
Trend watcherThe weekly trend run counted 916 events in weeks 30–41 for 8 work types at 5 sites. Ladder work at Northgate ran 3, 5 and 8 in weeks 39–41, against a baseline of 0.9 a week — so the rule fired and opened LA-2026-031. The chart marks the day the ladders arrived: 18 Sep, 24 LD-3800 ladders issued. Chambers at Marsh Lane and chemical handling at Kellford were watched, and did not fire.
Rule: three weeks rising, the last at least twice the 8-week baseline and at least 3 events.
- 03The common factor
What the 16 share — and where the same ladders went
Trend watcher11 of 16 used batch LD-3800; 12 of 16 were overhead service connections; 9 were contractor crews from Brackenfield Utility Services; 6 were on wet or soft ground. Time of day and crew were not shared — seven different crews. The stores records show 14 ladders of the same batch issued to Eastmoor on 5 Oct, with no report yet, and 6 unissued at Marsh Lane.
“Eastmoor crews do the same service connections. The alert and the strap action cover both depots.”

A voice note from pole 47/112
Dan Whitlock · Lineworker, NorthgateDan was strapping on at about four metres to transfer a service when the ladder kicked out at the base on the wet verge. Kofi was footing it and held it; the live LV service was right by his hand. The report reader transcribes the 38-second voice note, describes the 2 photos and ties each of 6 facts to the phrase or photo it came from — the missing strap is circled on photo 2, tag LD-3800-17.
“New ladder, no pole strap on it, same as the others in van NG-14. I came down slowly and we stopped the job. Nobody hurt.”

Four questions, and the tier is serious potential
ClassifierHigh energy present: yes — a fall from 4.1 m and a live 400 V service within reach. Released: yes, the ladder base moved. Serious injury: no. Direct control in place: no — no pole strap, top not tied, and footing a ladder is not a direct control. Serious potential, confidence 0.93. The duty manager, Owen Pritchard, is told at 15:53 and stands the crew down from ladder work at 16:02.
“High energy, released, no direct control — only chance and a colleague stopped a serious injury.”

Two reports, one event — both kept
Duplicate finderKofi Mensah of Brackenfield reports the same event from the same pole 25 minutes later. The duplicate finder matches pole, time and words and joins his report to Dan's, so the trend counts one event, not two. Nothing is deleted: in the inbox, NM-2026-04421 shows as “Joined to 04417”, and each man keeps his own report and gets his own reply.
Duplicates are joined, never deleted. Each reporter still gets a reply.
- 0708:24 · Confirmed
Nadia confirms, accepts the actions and answers both men
Nadia Farouk · Safety advisorSerious potential has to be confirmed by a safety advisor within 24 hours. Nadia confirms at 08:24, accepts the four proposed actions and sends both replies at 08:31 — 16 h 41 m after Dan's report, inside the 24-hour clock. Every agent step on the report sits on one list, from the voice note transcribed to her confirmation.
“Thanks, Dan. Your report of the ladder at pole 47/112 has been read and confirmed as serious. You were right about the strap.” — Nadia
- 08The actions
Highest control first
Action drafterThe action drafter proposes actions from the top of the hierarchy of controls, each with an owner and a due date. Substitution: issue stand-off pole ladders from stores until the straps are fitted. Engineering: fit pole straps to all 38 LD-3800 ladders before reuse — Northgate 24, Eastmoor 14 — Owen Pritchard, due Wed 14 Oct. Administrative: a toolbox talk on tying the ladder top before climbing, and a query to Halden Access Equipment on the order spec, owned by procurement.
Proposes only; the safety advisor accepts. Never closes an action.
- 09The alert
A one-page safety alert, in crew words
Action drafter · checked by Nadia FaroukSafety alert SA-2026-019 says what happened, why, and what to do from now: do not climb on an LD-3800 ladder until a pole strap is fitted — check the tag, LD-3800-01 to -44; use a stand-off ladder; tie the top every time, because footing is not enough on a round pole. It goes to 212 people: Northgate's 96 and Eastmoor's 88 overhead and service crews and 28 Brackenfield contractors, by text and the crew app.
“Report any ladder that moves, even a little. Every report is answered.”

Martin signs on his phone, and it goes out
Martin Achebe · Head of HSEThe Head of HSE signs every safety alert. Martin signs at 09:05 with the meaning “approved for issue”, and the alert is sent the moment he signs. The screen then tracks who has read it: 168 of 212 crew members so far. The trend was caught in three weeks — before anyone fell.
