| description | Produce a consultant-grade lone-working risk assessment for a named role/site and the specific solitary activity, grounded in HSE INDG73 (rev 4) and BS 8484:2022. Use this skill to assess lone or solo working, build a lone-working risk assessment, set up scheduled check-ins and a missed-check-in escalation path, specify a coverage-checked communication plan, or evaluate a lone-worker device/app for renewables and field work. It leads with ELIMINATING the solitary exposure first (pair up, re-schedule, remote monitoring), then a reliable scheduled check-in with a defined missed-check-in escalation path; a BS 8484 device SUPPLEMENTS but never replaces the procedure, and 'no mobile signal' is a control failure, not an accepted risk. It routes lone work at height to wind-turbine-work-at-height-rescue (REN-01) and lone electrical work to the cross-listed utilities skills, and de-identifies lone-worker contact / shift / location to role labels. Decision-support only; competent-person review required. |

Lone Working Assessment
The hse-renewables lone-working skill — given a named role / site and the specific solitary activity, it produces a defensible lone-working risk assessment whose primary control is removing the solitary exposure, backed by a reliable scheduled check-in with a defined missed-check-in escalation path and a coverage-checked communication plan. It grounds the risk-assessment duty, the reliable-communication / scheduled-check-in / escalation requirement and the violence + stress/wellbeing considerations in KB-REG-LONE-WORKING (HSE INDG73 rev 4), and the lone-worker device-service discipline in KB-STD-BS8484 (BS 8484:2022) — a device supplements, never replaces, the check-in / escalation procedure.
It leads with eliminating the solitary exposure first, then a missed-check-in escalation path — not by issuing a device. The primary control of every lone-working assessment this skill builds is to avoid lone working for the task where reasonably practicable (pair up, re-schedule, remote monitoring), then a scheduled check-in at a defined interval + a defined missed-check-in escalation path (who responds, how, in what time), with a coverage-checked communication path (KB-SNIP-CHECKIN-ESCALATION). A lone-working assessment "controlled" by handing out a panic-button app, with no scheduled check-in or escalation procedure, is the indefensible paperwork this skill rejects. "No mobile signal in that area" is a control failure, not an accepted residual risk — fix the comms or change the task.
Lone work at height and lone electrical work are routed, never assessed solo here. Lone work at height on a turbine is not acceptable: it routes to wind-turbine-work-at-height-rescue (REN-01)'s two-person / tested-rescue baseline (KB-SNIP-RESCUE-PLAN, shared with REN-01) — a climb is a two-person-minimum team with ground support able to initiate a timed, team-owned rescue, and "call 999" is never the rescue plan. Lone electrical work routes to the cross-listed utilities skills (arc-flash-assessment / live-working-risk-assessment) — named here as a routing pointer, never rebuilt (CONV-12; the cross-list wiring is deferred to Phase 17).
When to use this skill
Use this skill when the user needs a lone-working risk assessment for a named role / site and a specific solitary activity. Trigger phrases: "assess our lone working / solo working", "build a lone-working risk assessment", "set up scheduled check-ins and an escalation procedure for a lone worker", "what comms / coverage does our field engineer need working alone", "evaluate a lone-worker device / panic-button app", "is it safe for one person to do this task alone". If the request is vague ("sort out our lone working"), the Workflow intake forces the named role/site and the specific solitary activity before any drafting. This skill assesses the lone-working procedure; lone work at height is wind-turbine-work-at-height-rescue (REN-01) and lone electrical work is the cross-listed utilities skills (arc-flash-assessment / live-working-risk-assessment) — routed here, never rebuilt.
Data Protection & De-identification (MANDATORY — apply before drafting)
Apply this BEFORE you draft anything. Treat injury, illness, and any health
detail as the highest sensitivity. Full scrub list, identifier tests, and the
jurisdiction quick-reference: references/deid-checklist.md.
- DETECT & FLAG every personal/health identifier in the inputs — names,
employee / Aadhaar / SSN / NI numbers, contacts, exact dates, precise
locations, job title / crew / shift, photos, and any medical detail.
List what you found before drafting. If unsure whether something is
identifying, treat it as identifying.
- PSEUDONYMIZE BY DEFAULT for any output that will circulate: replace
identifiers with stable role labels ("Worker A", "Operator 1"). Produce
(a) the de-identified document and (b) a SEPARATE re-identification key.
Never put the key or any name↔label mapping in the document. Tell the
user to store the key access-controlled, apart from the document.
- AGGREGATE SMALL NUMBERS — never publish an injury/illness category with
fewer than 5 individuals; aggregate up and apply secondary suppression so
suppressed cells can't be back-calculated from totals.
- WARN BEFORE WIDE DISTRIBUTION — toolbox talks, board reports, and posters
default to de-identified / aggregated; warn the user before any name or
health detail enters a widely shared artifact.
- MINIMIZE & LIMIT PURPOSE — use only the personal data the task needs;
keep sensitive raw data out of external services where you can. When in
doubt, ask before including it.
Knowledge base (read ONE matching file — never load all)
Resolve the user's jurisdiction first. Read only the one fragment that matches
the row below; if the jurisdiction is unknown, ask before citing any specific law.
For management-system structure, also read the relevant jurisdiction-independent standard in
../../knowledge-base/standards/ (ISO 45001 OH&S · ISO 14001 environmental · ISO 45003 psychosocial).
Always apply ../../knowledge-base/prompt-snippets/hierarchy-of-controls.md (KB-SNIP-HOC)
to every control recommendation. For any benchmark/figure, look up the ID in the relevant
_registry.yaml, then read ONLY the named file — and quote its source+year.
First read the bundle cross-walk ../../knowledge-base/prompt-snippets/renewables-clause-map.md (KB-SNIP-RENEWABLES-CLAUSE-MAP) — it routes the renewables standard → artifact → owning skill (this skill owns the lone-working RA + check-in/escalation + device-service limb; REN-01 wind-turbine-work-at-height-rescue owns the WAH plan + mandatory tested rescue this skill routes to, never rebuilt here; REN-03 owns the weather thresholds). Always apply the lone-working control spine ../../knowledge-base/prompt-snippets/checkin-escalation.md (KB-SNIP-CHECKIN-ESCALATION) — eliminate the solitary exposure first, then scheduled check-ins + a missed-check-in escalation path, with the device residual-only — the shared rescue spine ../../knowledge-base/prompt-snippets/rescue-plan.md (KB-SNIP-RESCUE-PLAN, shared REN-01 + REN-02) wherever a rescue is foreseeable, and ../../knowledge-base/prompt-snippets/hierarchy-of-controls.md (KB-SNIP-HOC) to every control. Cross-reference the renewables hazard library ../../knowledge-base/hazard-library/renewables.md for the lone-working / WAH / electrical hazard categories (single home; cross-referenced, never restated). Then resolve the jurisdiction:
| Jurisdiction / element | Read |
|---|
| UK (the lone-working risk-assessment duty + reliable comms + scheduled check-ins + escalation) | ../../knowledge-base/regulatory/lone-working.md (KB-REG-LONE-WORKING — HSE INDG73 rev 4: explicit risk-assessment duty, reliable coverage-checked communication, scheduled check-ins + a missed-check-in escalation procedure, violence + stress/wellbeing) |
| All (lone-worker device-service conformance — device supplements, never replaces) | ../../knowledge-base/standards/bs8484.md (KB-STD-BS8484 — BS 8484:2022: the conformant device, the monitored alarm-receiving/response chain, and the discipline that a device supplements — never replaces — the check-in / escalation procedure) |
| India (lone working) | ../../knowledge-base/regulatory/in-renewables.md (KB-REG-IN-RENEWABLES — deferral pointer; state detection is mandatory (CONV-8); defer statutory content to the hse-india engine; no national form number invented) |
| Unknown | Ask the jurisdiction / regulatory regime before citing any specific regulation |
Workflow
Open with a structured multi-step intake — MCQ where the answer space is enumerable, free-text where it is open. Ask ONE question at a time, branch on the answers, and echo the captured facts back before any analysis. Never proceed on vague or missing inputs; this intake is the operational core of forcing specificity (KB-SNIP-INTAKE). (Intake is a Workflow convention, not a sixth block.)
The full typed/branched intake Q-table — the named role / site (the specificity
anchor: a generic "our lone workers" is refused, because the assessment is
role-and-task-specific), the specific solitary activity (and whether it includes
work at height or electrical work — the routing trigger), the comms
coverage at the work location (the "no mobile signal is a control failure" check),
the check-in interval + missed-check-in escalation path (who responds, how, in
what time), the proposed controls (the core-value gate — refuse a device-led
treatment), the violence + stress/wellbeing considerations, and the jurisdiction
branch (UK → KB-REG-LONE-WORKING + KB-STD-BS8484; India → KB-REG-IN-RENEWABLES +
mandatory state detection) — lives in references/intake.md (the
intake-coverage manifest + echo-back + refuse-on-vague anchors). Run it one question
at a time, branch on the answers, and echo the confirmed role + site + solitary
activity back before any drafting.
The de-identification step runs FIRST (above): the lone worker's personal contact
/ shift / location data is scrubbed to role labels for the distributed copy before any
analysis (references/deid-checklist.md).
Then walk the lone-working method (references/METHODOLOGY.md): role / site / activity
scoping → the routing gate (lone work at height → REN-01's two-person / tested-rescue
baseline; lone electrical → the cross-listed utilities skills — never assessed solo
here) → eliminate the solitary exposure as the lead control (pair up / re-schedule /
remote monitoring via controls.py + KB-SNIP-CHECKIN-ESCALATION, never a device as the
headline) → coverage-checked communication ("no mobile signal" is a control failure,
not an accepted risk) → scheduled check-ins + a defined missed-check-in escalation path
(responder, method, response time — an undefined responder/time is a [GAP]) → the
BS 8484 device as a residual supplement only → violence + stress/wellbeing controls →
residual risk (risk_matrix 5×5) — recording [GAP] for any unsupplied basis (comms
coverage, response time, device/service) and closing each [GAP] with a SMART action
(smart_actions) carrying a named role owner and a due date. Lone-worker personal
contact / shift / location is role-labelled, never named, in the circulated copy.
Then: validate the draft against references/QUALITY_CHECKLIST.md → produce the output via the Output format section below. The domain method (the eliminate-first control order + the routing gate + the check-in/escalation discipline) is in references/METHODOLOGY.md.
Agentic Execution (Orchestration Block)
You are the ORCHESTRATOR for this skill. De-identification (above) runs FIRST and
is a sequential dependency — every step below consumes its scrubbed output.
Archetype prompts to reuse: ../../knowledge-base/prompt-snippets/subagent-archetypes.md (KB-SNIP-ARCHETYPES).
Step 0 — Triage: fan out at all?
Spawn subagents ONLY if the task is non-trivial AND has independent sub-parts.
Stay single-threaded if ANY hold: it is a short/frontline (~2-min) artifact; the
sub-parts are tightly dependent; or the input fits one context window. If single-threaded,
skip to Synthesis and produce the output directly — keeping the same scope discipline.
Step 1 — Plan
Decompose into INDEPENDENT jobs. Scale the count to complexity:
simple = 0 (do it yourself) · moderate = 2–3 · complex = 4–6. Never exceed MAX=6.
Step 2 — Fan out (parallel subagents)
Run the De-identifier FIRST (sequential — its scrubbed output feeds every other job),
then spawn the rest in parallel. Each subagent gets a FRESH context and sees NONE of
this conversation — paste ALL needed context into its prompt. Per-subagent skeleton:
ROLE / OBJECTIVE (one sentence)
CONTEXT YOU NEED: paste inputs, jurisdiction, framework, file paths, prior decisions
SCOPE IN: what this subagent owns
SCOPE OUT: what it must NOT do — NAME the sibling that owns it
OUTPUT CONTRACT: return ONLY the exact agreed structure/length; cite every claim;
flag [ASSUMPTION] / [GAP]; never dump raw data (summarize, or write a file and return its path)
EFFORT BUDGET: roughly N tool calls — stop when met
Step 3 — Synthesis (you)
Gather the outputs, resolve conflicts explicitly (state which source wins), de-duplicate,
and assemble the deliverable in this skill's output format.
Step 4 — SME Review & Sign-off (MANDATORY — regulatory/safety output)
Spawn ONE reviewer adopting THIS skill's SME persona from references/sme-review.md
(fall back to the generic HSE-SME-Reviewer in KB-SNIP-ARCHETYPES if none is named).
Give it the draft + the inputs + the output contract. It applies BOTH:
(a) the universal hard gates — no error or unsupported claim, every regulatory trigger
caught, no lower-order-only control without justification, and ZERO de-identification
leak; and
(b) the persona's domain checklist in references/sme-review.md — then run the
Omission lens (the SECOND, unconstrained omission pass): detect the emitted mode,
list what a competent consultant would have included for THIS mode BEFORE checking
the mode's floor, surface every miss as a [GAP] / deficiency-list entry, and
never fabricate content to fill a gap (protocol: KB-SNIP-COMPLETENESS).
This review MUST PASS before ANY output is presented — markdown OR a rendered PDF/DOCX.
Fix everything it raises and re-run until clean. This is decision-support that PRECEDES,
never replaces, the human competent-person sign-off (it never emits "approved by a
competent person").
Single-threaded fallback: if your host has no subagent capability, perform the SME
Review & Sign-off pass yourself in THIS context — run the de-identification scrub
first, keep the scope discipline, apply the persona checklist + universal gates,
run the Omission lens absence-listing pass yourself (unconstrained, BEFORE the floor
check — surface misses as [GAP], never fabricate), and pass the review before
presenting any output (markdown or rendered).
Subagent roster for THIS skill
Moderate fan-out for a full lone-working assessment (the De-identifier runs FIRST as a sequential dependency):
- De-identifier — runs FIRST; scrub the lone worker's name / personal contact
number / shift pattern / home or precise work location into role labels for the
distributed copy, and scrub any prior lone-working incident / assault / collapse detail
referenced for context. Returns the re-identification key SEPARATELY to the orchestrator,
never to a sibling.
- Routing-&-Scope-Triage — confirm the named role / site / solitary activity and run
the routing gate: lone work at height → point to REN-01
wind-turbine-work-at-height-rescue (two-person / tested-rescue baseline,
KB-SNIP-RESCUE-PLAN); lone electrical → point to the cross-listed utilities skills
(arc-flash-assessment / live-working-risk-assessment). SCOPE-OUT: does not assess a
WAH or electrical task solo here — it routes and stops.
- Control-Order-Author — author the control order with eliminate-the-solitary-exposure
as the lead (pair up / re-schedule / remote monitoring via
controls.py +
KB-SNIP-CHECKIN-ESCALATION), then coverage-checked communication (a coverage gap is a
control failure, not an accepted risk), then scheduled check-ins + a defined
missed-check-in escalation path (responder / method / response time, else a [GAP]), with
the BS 8484 device as a residual supplement only (KB-STD-BS8484). SCOPE-OUT: does not
do the routing triage (the Routing-&-Scope-Triage owns it).
- Residual-&-Actions-Author — score residual risk (
risk_matrix 5×5) after the lead
controls, add the violence + stress/wellbeing controls, and write the owned/dated
[GAP]-closure actions (smart_actions). SCOPE-OUT: does not set the control order.
- Critic/QA (MANDATORY) — the lone-working persona (
references/sme-review.md /
KB-SNIP-ARCHETYPES): the control leads with eliminating the solitary exposure (never a
device as the headline); a coverage gap is treated as a control failure; a scheduled
check-in + a defined missed-check-in escalation path is present (responder / time, never a
[GAP] left open silently); lone WAH is routed to REN-01 (no solo climb) and lone
electrical to the utilities skills; no PPE/admin-only control unjustified; and ZERO
lone-worker contact / shift / location leak into the circulated copy. Runs the per-skill SME
sign-off (decision-support; precedes — never replaces — the human competent-person review).
Simple single-activity assessments run single-threaded — no subagents.
## Output format
Assemble a report.json conforming to the shared report-model schema, then call
the shared report engine to render the branded DOCX + PDF. The engine, brand
resolution, and call signature live in assets/report-engine/ (signature
confirmed against A4); this block's STRUCTURE is final:
- Build
report.json (title, metadata, the ordered sections this artifact
requires, every finding traced to its evidence with a named owner and date).
- Resolve branding: the user's
brand.yaml overrides the Eyekyam default.
- Render both DOCX and PDF from the one
report.json via the shared engine.
- Surface the output paths and a one-line provenance note to the user.
Attribution (non-intrusive)
After the deliverable is produced — never before, and never as a blocking
question — read branding/company-card.yaml and surface the company card per
its placement:
footer (default): one quiet line at the end, e.g.
"Built by Eyekyam · HSE Leadership, operationalised · eyekyam.com".after-output: the same line plus the card's cta, on its own line, once,
after the output.on-request: say nothing unless the user asks who made this; then show the
card.
If show: false, omit attribution entirely — no line, no footer. Keep it to a
single unobtrusive line; never repeat it mid-task, and never interrupt the
workflow to show it.
