Worked examples of
real isolation procedures.
Twelve equipment-specific lockout/tagout procedures across twelve industries, with the actual isolation-point structure each one needs. Free to read, free to download, no signup. They are examples to learn from — not documents to adopt.
Lockout is equipment-specific. So are these.
A generic checklist tells you to isolate, lock, tag and verify. It cannot tell you that a wind turbine's pitch UPS must stay live so the blades can be feathered, that a converter DC link holds stored energy after the grid disconnect opens, or that blade lightning receptors cannot be isolated at all. Each example below distinguishes the points you isolate from the points you must leave alone — because on real plant, that difference is the procedure.
Full energy isolation of plasma etch chamber A for scheduled chamber wet clean. Cl2/BCl3 metal etch chemistry.
Full isolation of CR-101 for mantle change. Includes upstream CV-200 feed conveyor isolation per interlock requirement.
Full energy isolation of RC-14 for weld gun tip change and reamer service. Entry into the cell.
Capper head rebuild plus filler bowl internal inspection. Includes DP-1 depalletizer isolation and CO2 purge.
Full rig de-energisation prior to rig down and move. Spans SCR house, drawworks, top drive, mud pump, BOP and mast. Multi-shift.
Launch track LSM cabinet service. Includes transfer track isolation and capacitor bank discharge. ASTM F770 maintenance.
Absolute possession of the Down Main for engineering work. PICOP-controlled. Includes 25kV OLE isolation and earthing.
B737-800 flap actuator change. ALL THREE hydraulic sources must be isolated - the flight controls are redundantly driven.
Annual haul rope inspection with tower sheave assembly change. ANSI B77.1. Evacuation drive must remain available throughout.
Nacelle gearbox inspection with hub entry for pitch bearing check. Rotor lock mandatory before hub entry.
Permit-required confined space entry into mud tank no.2 for cleaning and internal inspection. 29 CFR 1910.146.
Weld repair to the 6in outlet nozzle on TK-401. NFPA 51B hot work. Fire watch 30 minutes after work stops.
These are examples. Your procedures are yours.
Under 29 CFR 1910.147(c)(4)(i) the employer must develop, document and use energy control procedures specific to their own machines, and under (c)(6) must inspect them at least annually. A vendor cannot take on that duty and a customer cannot delegate it. Every example here refers to equipment that does not exist, and each one deliberately omits the site-specific facts only you can supply.

Setyr is purpose-built for hazardous energy control — lock registries, group lockout, person-in-charge custody and a tamper-evident record. Not a checklist bolted onto a work order system.
