Title
Lockout/tagout (LOTO)
Sector
Electrical
Description
Lockout/Tagout (LOTO) is the OSHA-mandated procedure for isolating hazardous energy before maintenance or repair — especially critical in battery manufacturing where electrical, mechanical, hydraulic, and stored chemical/electrical energy sources all exist. As a hard skill it requires reading energy-isolation diagrams, applying multiple personal locks correctly, performing zero-energy verification with appropriate test equipment, and never restoring power without team accountability. Maintenance teams apply this on every intervention into a coater drive, every cell-finishing line stoppage for changeover, and every approach to a partially-assembled pack with stored DC voltage.

Wiring — selecting conductor size, color-coding, terminating, routing, labeling — is the daily detail work that turns a schematic into a functioning electrical installation on a battery production line or in a pack. As a hard skill it requires NEC table reading for ampacity, understanding stranded vs solid for vibration and flex life, proper crimp technique with calibrated tools, and the documentation discipline so the next electrician can trace a wire back to its source. Electricians apply this on every panel build, every cable harness on a pack-test rig, and every re-pull when a sensor fails and has to be replaced without disrupting the rest of the harness.
