Lockout/Tagout (LOTO)
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.
