Work at the point of risk
Clearance, controls and field evidence stay connected to the job.
Operational control for hazardous work
Know what is live.Know what must happen next.
Plan, authorize, isolate, execute and close every hazardous job in one traceable permit workflow. Work starts only when the required people and controls are ready.

Designed for demanding work
One safety workflow. Many kinds of site.
From live plants to infrastructure projects, coordinate hazardous work with clear ownership, verified controls and evidence that stays with the permit.
Control hazardous energy
Isolation steps and verification remain visible before work begins.
Keep the whole site aligned
Teams share one current view of permits, hand-offs and exceptions.

One flow, from request to restoration
Each stage has an owner and a gate. The permit only moves forward when the gate is satisfied, and the status your whole site sees changes with it.
- 1
Raise the permit
DraftPermit receiver and operator
Choose the permit type, location, time window, crew and machinery. The HOD is notified as soon as a draft exists, not when it lands on their desk.
- 2
Clear conflicts
Pending approvalAutomatic
SIMOPS compares location, schedule and hazards against every live and pending permit. A clash goes back to the HOD instead of out to the site.
- 3
Approve
Pending approvalHOD, then safety officer
The HOD reviews risk and priority, the safety officer reviews site conditions and gas readings. Either can send it back or reject it, and the reason is kept.
- 4
Isolate
ApprovedExecutor, verified by safety
A machine-specific LOTOTO plan walks through each energy source in order: lock, tag, try out, photograph. Work stays blocked until every point is verified.
- 5
Do the work
ActiveExecutor and crew
Time-stamped progress with photos. Pause, near-miss and accident reports sit on the same screen, and an accident stops the permit automatically. Multi-day jobs are revalidated every morning.
- 6
Restore and close
ClosedExecutor, issuer, HOD
Isolations come off in sequence with evidence, the area is declared clear, and the issuer and HOD sign the permit off. The whole history stays attached.
Everything the permit touches, in the same system
People, machines, isolations, readings and incidents stay linked to the permit they belong to, so nothing has to be reconciled after the fact.
Plan the work
- Permit types
- Hot work, confined space, work at height and your own types, each with its own fields and colour.
- SIMOPS
- Automatic detection of overlapping work by location, schedule and hazard.
- Gas testing
- Readings recorded against the permit before approval and on revalidation.
- Multi-day permits
- Daily progress, daily safety revalidation, extensions and validity checks.
Control hazardous energy
- LOTOTO plans
- Isolation procedures per workstation and machine, covering every energy source.
- Sequential lockout
- Lock, tag and try-out steps enforced in order, each signed by a named person.
- Evidence capture
- Photos and logs stored with the step they prove.
- Restoration
- De-isolation verified step by step before equipment returns to service.
Respond and learn
- Incidents and near misses
- Reported from the job, linked to the permit, people and machine involved.
- Investigations
- Root cause, corrective actions and reminders when actions go overdue.
- Notifications
- In-app and email alerts for approvals, rejections, conflicts and expiring permits.
- Dashboards and reports
- Views for HODs, safety and management, with PDF, Excel and CSV exports.
Run the organisation
- Master data
- Departments, locations, workstations and machinery in one catalogue.
- Workforce
- Employees, contractors and agencies, with the roles they are allowed to hold.
- Role authority
- Issuer, executor, supervisor, safety officer, HOD and administrator, enforced on every action.
- Subscriptions
- Modules and usage managed per organisation.
What changes when the permit book goes digital
Safety comes first by design. The system will not let work begin until the mandatory steps are done, and it remembers who did each one.
| Paper and spreadsheets | With PermitWiseAI | |
|---|---|---|
| Approvals | Chasing signatures around the plant | Routed to the right Approver and safety officer, with reasons on record |
| Overlapping work | Discovered on the shop floor | Flagged by SIMOPS before anyone approves |
| Isolation proof | A tick in a register | Each lock, try-out and restoration signed and photographed |
| Multi-day jobs | Yesterday's permit reused without re-checks | Revalidated every day before work resumes |
| Audits | Days of digging through files | Complete history per permit, person and machine |
| Visibility | Phone calls to find out what is live | Live dashboards for every level of the site |
Access and evidence you can defend in an audit
A permit is only worth the signatures on it. These are the controls behind every one.
Single sign-on
OpenID Connect sign-in, with a forced password change the first time an invited user logs in.
Enforced authority
Roles are checked on the server for every action, so a screen can never approve what its user may not.
Tenant isolation
Every record is scoped to its organisation. One customer's permits are never visible to another.
Audit trail
Who created, approved, rejected, locked or closed what, and when, kept with the permit.
