Draft task-and-site-specific SWMS, assemble isolation points from the plant register, check permit packs and surface stale documents — while the issuing officer, isolation officer and statutory mine manager keep every signature.
Take the task, the work area, the plant and the crew from the work order, shutdown plan or permit request.
02
Read the site's own procedures, PHMPs, isolation standards, drawings and plant register at their current revision.
Reason
03
Draft the SWMS against this task and this work area, carrying the site's own control wording rather than a template's.
04
Assemble the isolation points for the job from the plant register and the P&IDs, including stored-energy sources.
05
Check the permit pack against the site's requirement list and name what is missing, unsigned or out of date.
Decide
06
Flag generic wording, isolation points nobody has verified at the plant, and documents that have gone stale.
07
Route what it cannot resolve to the supervisor, the isolation officer or the issuing officer named for that job.
Out
08
Present the SWMS draft, the candidate isolation list and the gap list — as drafts, with the sources beside them.
09
Retain every source read, the revision of each standard used, the rationale and every officer amendment.

No human action required
Stages 1 to 4 run without a person in the loop — reading, drafting and the gap list finish before anyone is asked to read anything. Nothing is issued in that stretch.
5DecisionSplits on draft confidence and the risk class of the job
Routine job, no open gaps
Reaches the officer as a complete draft.
High-risk job or open gap
Goes to the supervisor before it goes further.
Supervisor or issuing officer
Reads the draft, the candidate isolation list, the sources and the gaps, then decides whether to amend, refuse or sign.

Human approval stays in control
Outside the boundary — human approval required8 items
Issuing a permit to work or hot-work permit.
Signing an isolation certificate or authorising a lockout.
Authorising entry to a confined space.
Clearing, removing or overriding an isolation or lockout.
Automation boundaryAgent acts unaided
✓Draft the SWMS against the task, the work area and the site's own standards.
✓Assemble isolation points from the plant register.
✓Check a permit pack against the site's requirement list.
✓Trace which documents a change to plant or procedure touches, and what has gone stale.
Write actions run only inside the approval boundaries agreed during implementation. A permit or certificate is never one.
Bypassing an interlock, a guard or a protective device.
Declaring an area safe or lifting an exclusion zone.
Signing off a risk assessment or a SWMS.
Changing a procedure, standard or isolation register.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value landsValue 01 – 04
Every job needing paperworkWork order, shutdown task or change
03Drafting & checking
Work to the site's own standards
Use the mine's procedures, PHMPs, isolation standards, drawings and plant register at the revision current for that shift.
01Approved path
Stop the template being the document
The draft starts from this task and this work area, so the officer's reading goes on whether the controls fit the job rather than on stripping a template back to it.
02Human review
Put the gaps in front of a person first
Unverified isolation points, missing signatures and stale documents reach the supervisor before the pack reaches the issuing officer.
04Build an evidence trail
Retain the sources read, the revision of each standard, the isolation points proposed, the confidence and every officer amendment — on both paths.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.
Safety management systemCintellate · INX InControl Damstra · Document control
Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and the permit pack
Each control wraps the one inside it. A draft clears every layer before an officer reads it, and the signature sits outside all six.

How Nestack evaluates it
Evaluate the whole pack — not only the SWMS an officer reads.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Sev-1 · a crew could work to a wrong documentSev-2 · a defective document reaches an officerSev-3 · drafting degrades, more is amended
A draft is only as current as the plant it describes. Re-piped equipment, crews new to the site and jobs with no precedent draw the amendments; routine shutdown work does not. Nestack reports performance by slice, not only in total.

Evidence-linked improvement
A wrong document is fixed everywhere it appears
An amendment to one SWMS does not close the finding. The standard behind it, the register entry or the retrieval rule is changed under change control.
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Officer amendments or audit findings move in a cohort.
02Diagnose
Which revision did it read, and why did the check pass it?
03Improve
The rule or standard reference goes through change control, with an approver.
04Verify
Re-drafted against held-out jobs from the affected cohort.
05Learn
That job is kept as a regression case and the rule enters the drafting runbook.
Learn → DetectThe return edge. A change to a standard or an isolation register is made by a named approver.
