Electronic Permit to Work Software (ePTW)

Electronic Permit to Work Software (ePTW)

Electronic Permit to Work (ePTW) software for high-risk operations. Every permit type, isolation and crew in one connected system, configured around your site.

Run every permit your site uses: hot work, confined space, work at height, electrical and your own custom permit types. Zentri digitizes the full workflow, from planning and authorization through crew sign-on, execution, handback and closeout, so every step is recorded and traceable.

Permits link directly to Lockout/Tagout isolations, with zero-energy verification before work starts. LiveSite shows every active permit, isolation and crew on your own site layout drawing, making simultaneous operations (SIMOPS) visible so supervisors can spot overlapping work before they approve it. ImpactView maps power dependencies and checks redundancy before you isolate.

The result: fewer missed hazards, reduced downtime, less time chasing paperwork, and audit-ready proof that every control was applied and verified. Built for Pharma & Life Sciences, Data Centers, Manufacturing, Energy & Heavy Industry, Construction and Food & Beverage, with CMMS integrations, SSO, offline field execution and full implementation support.
