LOTO is hard to control when every step lives somewhere different.
Procedures, worker sign-on, verification, closeout records and periodic reviews are often managed across paper, spreadsheets, shared drives and disconnected systems.
Procedure. Execution. Evidence.
Zentri connects the full lockout tagout lifecycle in one platform — from controlled procedures to live execution and audit-ready evidence.

Procedure control.
Create controlled, equipment-specific LOTO procedures that stay connected to the work they support.
Equipment-linked procedures
Tie each procedure to the right asset, energy sources and isolation points.
Approval and version control
Keep procedure status, approvals and revisions visible.
Execution-ready requirements
Define checks, verification steps and required fields before work begins.
Templates and tagging
Standardize rollout across sites and link records to equipment in the field.
- Electrical · 480 V · 3-phaseMCC-B-12 breaker
- Steam · 150 psiBlock valve V-7
- Hydraulic · 1 800 psiIso valve HV-3
Execution control.
Execute approved lockout plans from your mobile device, on the floor, following the right steps in the right order.
Worker sign-on
See who is working under each active lockout.
Group LOTO visibility
Track internal teams, contractors and shift changes.
Isolation and verification
Guide teams through required steps and capture evidence as work happens.
Controlled closeout
Confirm workers are clear, post-checks are complete and the job is ready to close.
Evidence control.
Keep a connected record of what happened, who was involved and how the work was closed out.
Audit trail
Capture each action with user, time and context.
Completed plan records
Review completed lockouts by procedure, equipment, worker, site or date.
Closeout evidence
Retain sign-off, verification and closeout records in one place.
Built-in auditing
Audit training records and procedures to confirm they’re still correct. Track review status, findings and overdue items.
The controls behind a scalable LOTO program.
Manage users, roles, sites, notifications, tagging, exports and activity logs behind every procedure, plan and review.
Paper keeps every step siloed.
The risk is not one missing form. It is procedures, sign-on, verification, closeout and review all living apart.
