Lockout / Tagout pre-work checklist
A structured, check-it-off safety sequence for licensed electricians before working on a circuit — identify every source, lock out, tag out, and verify zero energy with a known-good tester. Test before touch.
For qualified / licensed electricians — general safety reference, NOT a substitute for OSHA, NFPA 70E training, your employer's safety program, or the NEC. Electrical work can be fatal; always verify de-energization with a known-good tester (test-before-touch). When energized work cannot be avoided, an energized-work permit, arc-flash assessment, and proper PPE are required. Follow your site's written program.
This is an educational, generalized checklist of common steps in an electrically-safe-work-condition process — it cannot account for your specific equipment, voltage class, employer procedures, or site hazards. Stored energy (capacitors, batteries, springs, hydraulics, gravity, UPS/PV/generator back-feed) and multiple feeds are common, dangerous surprises. Always follow OSHA 1910.147 / 1910.333, NFPA 70E, your employer's energy-control procedure, and local code. Progress is saved only in your own browser.
