Job hazard analysis that writes the tailboard for this job, at this site, in today's weather
Every high-energy hazard of this job named and controlled before work starts.
See one case, screen by screen ↓Before every job, the person in charge has to brief the crew on the hazards, the procedures, the special precautions, the energy source controls and the PPE — 29 CFR 1910.269(c) asks for it, and again when the job or its hazards change. In practice the tailboard is written in the cab at 07:00, from memory or copied from the last job. It says “electrical”, “working at height”, “traffic”. It does not say which conductors stay live, that a customer's standby generator back-fed this section last year, that a water main runs under the footpath where the outriggers go, or that the gusts pick up at 10:00.
That site knowledge exists, but in other systems: near misses and incidents in the safety system, patrol notes in asset records, registered generators in the connections register, buried services in GIS. No crew lead looks them up before the truck rolls. The weather changes during the job, but the paper form is written once. And a supervisor cannot read hundreds of paper forms a day, so the high-risk jobs are found after the fact. At the sample depot in the working solution, an audit of 200 paper forms in June found a direct control written down for only 71 % of high-energy hazards.
Estimated split for one high-risk overhead job, in minutes, done thoroughly by hand and with the solution. By hand, the site and weather look-ups are the steps most often skipped; the 6-minute supervisor review is the median seen in the working solution.
Six agents build each tailboard from the job, the site’s history and today’s weather; the crew lead briefs and the crew signs.
Tuesday 13 October 2026, Eastfield depot of Lumina Utilities. Line Crew 14 is due at pole P-11872, outside 214 Kestrel Road, at 07:30 to replace a cracked crossarm and two pin insulators on 11 kV feeder EF-07. Here is what happens next, screen by screen, in the working solution.
On the tablet in truck T-214, Dario sees his three jobs for the day and picks the first, WO-4471828. The 11 kV span P-11871 – P-11873 is isolated under switching programme SW-26-3318 and permit PTW-26-08812; the 400 V circuit underneath stays live to keep 38 customers on supply. The job reader and the hazard and control writer put the first four hazards on the energy wheel from the work order and procedure SWP-DIS-112: the isolated 11 kV, the live LV 0.9 m under the crossarm, work at height from the bucket at 11 m, and the 38 kg crossarm that carries about 3,700 J if it falls from 10 m.
“Stored on the tablet · signal is not needed to build, review or sign”
The site history finder searches 5 years within 200 m and the same feeder section and adds five hazards, each tagged with its source. The one that matters most: near miss NM-2025-0614, two poles away. Also a patrol note of a wasp nest under this crossarm, a vehicle that struck pole P-11874 on Kestrel Road in 2023, Eastfield Primary School 180 m east with drop-off at 08:15 – 08:50, and Lumina's own 300 mm water main 1.2 m under the north footpath.
Back-feed from a customer generator — high energy · control room confirms the generator is locked off and tagged
Every event opens on a street plan of Kestrel Road, poles P-11868 to P-11876, with the feeder, the live LV, the water main, the school and the cold store pinned. On 14 March 2025, Crew 6 isolated and earthed this section for a pole-top fuse change. On test before touch at P-11870 the line read 11 kV: Kestrel Cold Store's 250 kVA standby generator had started on loss of supply and back-fed through transformer TX-4471.
“Nobody was hurt; work stopped.” — near miss NM-2025-0614
At 07:12 the forecast at the site was 9 °C, dry, no lightning within 50 km, gusts 34 km/h — under Lumina's 40 km/h limit for aerial devices. Two minutes later the weather watcher rechecks: gusts of 42 km/h from 10:00. The tailboard adds “Bucket work restricted above 40 km/h” with three direct controls: aerial work finished and the bucket stowed by 09:45, an anemometer reading at bucket height before each lift, and stop and lower the bucket if gusts pass 40 km/h.
10 hazards · 7 high energy · 7 of 7 with a direct control
The emergency plan names the nearest emergency department — Eastfield General Hospital, Mill Lane, 6.2 km, 11 minutes — what to say when calling 112, Dario as bucket rescuer at the lower controls, Noel Fry with the first-aid kit and AED, the control room on radio channel 3 and the muster point. The crew checker reads every card against the roles the job needs and finds that Lewis Brandt's traffic controller card expired on 2 October. It proposes a swap; Dario accepts.
Crew checker: “Noel Fry (valid to Mar 2027) takes traffic control; Lewis moves to ground support.” — the crew lead decides
“Compare with yesterday's form” puts the copied form next to this job. Yesterday's form had four lines — “Electrical — stay clear”, “Working at height — fall protection”, “Traffic — cones out”, “Slips and trips” — with no energy sources named and no site or weather. This job has ten hazards.
“6 of the 10 hazards — the back-feed, the live LV, the wind, the wasps, the water main and the school — would not have been on a form copied from yesterday.”
The review router scores the job against Eastfield's high-risk rules and sends it to Priya with three reasons: the 400 V circuit stays live under the crossarm, the Kestrel Cold Store generator back-fed this section, and aerial work with gusts over the 40 km/h limit. On her laptop she sees every high-energy hazard with its direct control, the site and the live sign-on. She approves with one condition, and it goes onto the crew's tablet.
“Approved at 07:19 with a condition. Aerial work stops at 09:45. Anemometer reading logged before each lift.”
At the truck, Dario opens “Review together”: one hazard at a time in large type, read aloud to the crew, with its energy, where it came from and its controls. The wind comes first. When all ten have been read, Dario marks “Crew has reviewed all 10”, and only then can the crew sign on.
“Review together · read each hazard out loud with the crew”
Each person signs on the tablet in their role: Asha in the bucket, Lewis on ground support, Noel as traffic controller, Dario as person in charge and bucket rescuer. Every signature is stamped with the time and the place — P-11872 ±6 m. With the supervisor's approval in and every high-energy hazard controlled, the Start work button unlocks.
“Ready. Every high-energy hazard has a direct control; the crew has signed.”
Record TB-26-118204 is filed with 10 hazards, 7 high energy and 4 of 4 signatures, and work starts at 07:31. The record cannot be changed after sign-on; a change becomes a re-brief, signed again. The weather watcher keeps rechecking the forecast at the site every 30 minutes until the job is closed.
Re-briefs: “Wind — briefed before sign-on”
The same crossarm job, seen by the five people who brief it, approve it and answer for it — what their day looked like, and what it looks like now.
Six agents build each tailboard from the job, the site’s history and today’s weather; the crew lead briefs and the crew signs.
Reads the work order picked on the tablet — job type, assets, voltages, what is isolated and what stays live, switching programme, permit, crew, truck and job window — and pulls the safe work procedure for the job type.
Searches 5 years within 200 m and the same feeder section — incidents, near misses, patrol notes, registered generators, buried services and schools — and says what each event adds to the tailboard.
Gets the forecast at the site for the whole job window, applies the weather rules for aerial devices, lightning, heat and ice, and rechecks every 30 minutes until the job is closed.
Writes each hazard with its energy and source on the energy wheel, marks high energy above 680 J, proposes a direct control for each from the library and the procedure, and drafts the emergency plan.
Checks every person's training and cards against the roles the job needs — bucket rescue, traffic control, live LV, first aid — and flags expired or missing cards with a role swap inside the crew.
Scores the tailboard against the high-risk rules, sends high-risk jobs to the supervisor with the reasons, and files the signed record with time, place and every signature.
Owns the tailboard and can stop the job; the supervisor approves high-risk jobs. The agents propose; a named person decides.
Ask in plain words about today's jobs, a hazard or a tailboard — or say what to change. Every answer points to its source.
Why is the Kestrel Road job high risk?
Three reasons, each from a different source. The 400 V circuit stays live 0.9 m under the crossarm. Two poles away, the Kestrel Cold Store generator back-fed this section in March 2025. And gusts of 42 km/h are forecast from 10:00, over the 40 km/h limit for bucket work. All 7 high-energy hazards have a direct control.
Which jobs have lifts after 10:00 when the wind picks up?
Four: Crew 9 on Brookfield Road, bucket 10:00–13:00, re-brief asked 07:14; Crew 11 on Quarry Road, crane lift at 10:30, waiting for the supervisor; Crew 6 on Ashby Road, bucket at 13:00, re-brief asked; and Crew 14 on Kestrel Road, where aerial work now stops at 09:45.
Add the generator lock-off to every job on feeder EF-07
Done. New site rule: any job on EF-07 section 4 adds “back-feed from the Kestrel Cold Store generator” with the control “generator locked off and tagged, confirmed by the control room”. It applies to 3 more jobs planned this month, and it is in the hazard library as a draft for Grace Adeyemi to publish.
Which high-energy hazards started without a direct control this month?
12 of 3,914 at Eastfield since 14 Sep. The most common were a live adjacent phase with no cover-up named (3) and a crane lift with no tag line named (2). Every one was caught at the supervisor call or the field check, and the crew re-briefed.

What makes a job high risk, the weather limits, the look-back at the site and how long records are kept are settings, chosen by the depot.
| Setting | Default | Choose from |
|---|---|---|
| Live conductors in or under the work | On — high risk | On · Off — any voltage left live inside the work zone sends the job to the supervisor |
| Aerial work near the wind limit | Within 10 km/h | Within 10 km/h · Within 5 km/h · Over the limit only |
| High-energy hazards on one job | 5 or more | 4 or more · 5 or more · 6 or more — the count above which the job is high risk |
| Approver for Eastfield crews | Priya Holloway | Priya Holloway · Ken Salter (deputy) |
| Bucket work restricted when gusts are above | 40 km/h | 35 km/h · 40 km/h · 45 km/h, forecast or measured |
| Stop overhead work for 30 minutes after a strike within | 10 km | 10 km · 15 km |
| Recheck the forecast at the site | Every 30 minutes | Every 15 minutes · Every 30 minutes · Every 60 minutes, until the job is closed |
| Look back at the site | 5 years · 200 m · same feeder section | 3 years · 100 m, or 5 years · 200 m · same feeder section, or 10 years · 300 m |
Every figure is labelled: a target the solution is built to, an estimate, a typical published result, or a proven one.
“demo” = seen in the working solution, on its sample depot data · “target” = the design goal, measured in the live solution · “estimated” = our estimate · “typical” = published figures (BLS Census of Fatal Occupational Injuries — power-line installers at about four times the all-worker fatality rate; Intelex energy-based safety insight report, summarising field experiments — about 30 % better hazard recognition with the energy wheel). Context: 29 CFR 1910.269(c), job briefing before each job; EEI high-energy control assessment (HECA), high energy above about 680 J (500 ft-lb). Lumina Utilities, its depots, streets, customers, records and the people named on this page are fictional — characters and sample data in the working solution.
Software that builds the job hazard analysis — the tailboard or job safety briefing a crew holds before work — for the specific job, and records who was briefed and when. Job Hazard Analysis builds it on the crew lead's tablet from the work order, the procedure, the site's history and today's weather, and gives every high-energy hazard a direct control before work starts.
When the crew lead picks a job, six agents read the work order and procedure, search the site's history, get the forecast at the site and check the crew's cards. They write each hazard on the energy wheel with its source, mark high energy above 680 J, propose direct controls and draft the emergency plan. In the sample job it was built in 9 seconds with 9 hazards from four sources; the weather recheck two minutes later added the tenth.
It searches near misses, incidents, patrol notes, registered generators, buried services and schools within 200 m and on the same feeder section over 5 years, and rechecks the forecast every 30 minutes. On the Kestrel Road job, 6 of the 10 hazards — including a back-feed from a customer generator and gusts over the bucket limit — would not have been on a form copied from yesterday.
It is built around those subjects: for each job it names the hazards, the procedure, the special precautions, the energy source controls and the PPE, and a change in weather, hazards, crew or scope asks for a re-brief. Each person signs with time and place, and signed records cannot be changed. Your own safety team decides how it fits your programme.
Yes. The crew lead owns the tailboard, can add or change hazards and can stop the job; any crew member can stop work. The agents propose and never remove a hazard a person added, never mark a control as in place, never assign people and never approve a tailboard. High-risk jobs need the supervisor's approval before work starts.
Yes. The tailboard is stored on the tablet, and building, reviewing and signing do not need a signal. It is sent when the signal returns.
Yes. The hazards and direct controls by job type, the weather rules, the site rules, what makes a job high risk, the approver, the wind and lightning limits, the recheck interval, the look-back at the site and how long records are kept are all settings. A change to the library can be tested on last month's jobs before it is published.
The Agentic Solution Engine builds and deploys it from your requirements and documents — your safe work procedures, safety rules, tailboard form and a sample of work orders and site history — and it goes live once every quality gate has passed. We will walk you through it on your own jobs first.
