Lockout/ Blockout Training

Learn about lockout/ blockout training for employees who may encounter hazardous energy sources or machinery that could become energized during the course of their work.

Lockout/ blockout (LOBO) practices ensure that all energy sources are disengaged or blocked, and that electrical sources are de-energized and locked in the "off" position during work or repair. Read UCSD's Lockout / Blockout Policy (PDF) for complete details.
