Electrical Safety

1st. Metal is a great conductor of electricity

  • Don’t wear metal jewelry or watchbands when working on electrical circuits.
  • Use tools with non-conducting handles.
  • When possible, work on electrical circuits with 1 hand, keeping the other away from conductive materials.

2nd. Another decent conductor of electricity is water

  • Never work with electrical circuits with wet hands or on a wet floor.
  • If there is a spill, shut off the main power before doing anything else.

3rd. A so-so conductor of electricity are humans

  • Don’t touch electrical circuits with your fingers.
  • Treat all electrical devices as if they are energized.
  • Disconnect the power source before working on electrical circuits and devices.
  • When possible, work on electrical circuits with 1 hand, keeping the other away from conductive materials.
  • Should someone come into contact with electricity, don’t touch them; shut down the main power.
  • Never touch anyone’s electrical circuits unless invited to do so.
  • Enclose all electrical contacts and conductors.
  • Always de-energize electrical circuits when done working with them.
  • Do not wear loose or hanging clothing near electrical equipment.
  • Always drain capacitors before working near them.
