Permit to Work + Lockout Tagout
PTW and Lockout Tagout, connected.
Two records on one thread. The permit's isolation block links the lockout plan, so authorization waits until every point is verified.
Isolation plans are created, linked and controlled alongside your permits — in the same job.Explore Lockout Tagout →
