So does every single energy isolation REQUIRE a written procedure/plan that identifies the types of energy, their magnitude, the means used to isolate them, and the means used to verify zero energy state (ZES)? YES… there is ONLY ONE (1) special exemption that excuses us from having a task-specific isolation procedure/ plan, and that exemption can be found in 1910/147(c)(4)(i). But before we get too excited about OSHA giving us a loophole to having a WRITTEN ISOLATION PLAN for every LOTO, we need to see the eight (8) criteria that OSHA has set forth for the “exception” to apply, and I do think many will be sorely disappointed…
