De-energized Parts

All electrical parts exceeding 50 volts will be de-energized before an employee works on or near equipment unless:

• The de-energizing creates a more hazardous situation
  
  
• The equipment, by design, cannot be shut down

When any employee is exposed to direct or indirect contact with parts of fixed electrical equipment or circuits which have been de-energized, the electrical energy source will be locked out.
