Permit to Work
Control hazardous work through one permit operating model, where scope, TRA, LOTOTO, approvals, timing, readiness, and field conditions stay connected before, during, and after execution.
Permit to work as live control around hazardous work.
Vinkey turns permits, TRA, LOTOTO, approvals, and live field execution into one permit operating model instead of disconnected forms, signatures, spreadsheets, and side processes.
Work permits
Request, review, issue, revoke, and close in one governed workflow
TRA
Hazards, controls, and scoring stay tied to the exact permit
LOTOTO plans
Isolation is prepared before issue and remains tied to permit state
Simultaneous ops
Conflicting work stays visible while permits are live in the field
Permit as a control process
A brief view of how permit-required work moves from scope and review to issue, live control, and safe handback.
Step 01
Define the job
Capture the exact work, location, timing, asset boundary, and field conditions that matter before approval starts.
Step 02
Review risk and readiness
Assess TRA, approvals, prerequisites, and conflicts with the right operational context still in view.
Step 03
Prepare safeguards
Link measures, documents, isolations, and readiness checks before the permit reaches the field.
Step 04
Issue under control
Issue only when the job is genuinely ready to start under the approved conditions.
Step 05
Hand back safely
Keep suspension, revocation, reinstatement, close-out, and handback traceable after issue.
Why permit-to-work often fails in practice.
Most permit tools digitize forms but leave the real control decisions scattered across separate approvals, risk notes, isolation records, and field conversations. Vinkey governs how hazardous work is scoped, reviewed, isolated, issued, and handed back in the field.
Benefit
Treat permit to work as an operating model, not a document flow
Run review, preparation, issue, suspension, revocation, and close in one governed workflow
Route high-risk and special-situation work to the right approvers with explicit control logic
Keep permit control inside the same operating system as the work it governs
Benefit
Prepare permits with stronger operational context
Recommend risk category, safeguards, and documents from the actual job and location context
Surface simultaneous operations in the same permit context before and during issue
Make permit quality more consistent across teams, contractors, assets, and shifts
Benefit
Make issue and handback depend on real readiness
Attach LOTOTO plans directly to the permit before issue where isolation is required
Prevent issue until linked isolation and key prerequisites are genuinely ready
Keep dependent permits, isolations, field changes, and handback conditions traceable until work is closed
Connected around the same work.
These domains are often used together because they operate around the same execution flow.
