Electrical Safety Safe Practice

Common Sense Practices

  • Allow for proper ventilation around power-dissipating equipment.
  • Follow your nose! Identify “hot” or unusual smells around equipment. Ask others to assist you.
  • Turn off unused equipment (as appropriate).
  • Prior to activation of remote (includes out of sight) equipment, verify that the area is clear of personnel and secure from access.
  • Never leave a potentially hazardous equipment configuration unattended for any reason.
  • Use lockout/tagout procedures to prevent the operation of hazardous equipment.
  • Recognize hazards for others. Use warning signs to communicate possible risks.

Incorporate Safety Awareness

  • Pre-plan the job.
  • Review procedures with a second qualified person.
  • Maintain a safe working distance from exposed circuitry.
    • Federal guidelines recommend 0.6 meters for voltage from 1 to 15 kV.
    • Consider barricades and warning signs.
  • Use insulating materials to the maximum extent possible.
  • Review emergency response procedure.
  • Review a means of evacuation if necessary.

High-Voltage Work Practices

  • De-energize to the maximum extent possible.
  • Lockout and tagout to prevent premature activation by others.
  • Maintain safe working distances from energized equipment.
  • Test circuits for presence of voltage before contact is made.
  • Use insulating materials and tools.
  • Remove conductive jewelry, metal buttons, or zippered clothing.
  • Avoid nylon, rayon, polyester, or acetate clothing; cotton is best.
  • Use only one hand; keep the other in your pocket or behind your back.
  • Wear rubber-soled shoes.
  • Provide proper lighting.
  • Maintain proper housekeeping: minimize loose hardware and tools; eliminate hazards to trip over.
  • Control your environment to avoid unsafe acts.
