  1. Energized electrical circuits.
  2. Nip points, pinch points, or points of operation.
  3. Temperature extremes of machinery.
  4. Arc effects of electrical equipment.

Only the person placing the lock out device and tag on the switch or energy isolating device may remove same.

Facilities Services personnel will follow the procedures of the lock out/tag out plan of their departmental Electrical Safety Program.
