Safety precautions

  1. Never work on a live circiut.
  2. When working on a circuit, make sure that the switches are off.
  3. Check the testers regularly.
  4. Reduce loads as much as possible before opening the switch of the main fuse box and circuit breaker.
  5. Check faulty circiuts before replacing a fuse or resetting the circuit breaker.
  6. Do not replace a fuse with higher rating unless the conductorsd and loads are designed for such rating.
  7. Return all cover after work completion.

Safety precautions to prevent burns, shocks, and flashes when working with electrical installation.

  1. Perform only the job you are tasked to do
  2. Regard all electrical equipment as “live” unless you are sue the circuit is “dead”.
  3. Wear stiched safety shoes rather than nailed shoes.
  4. Use only one hand at a time to avoid hand to hand shock or burn through the body.
  5. Study and familiarize youyrself with all the equipment or lines before making any changes.
  6. Watch the distance between you and the “live” conductors.
  7. Use gloves when working with circuits.
  8. When in doubt of the conditions off all equipment, tools, devices, “live” panel frames of

Hand tools

  1. Always uae the proper tool for the job.
  2. When carrying tools, always keep the cutting edge down.
  3. Keep hands clean when using tools.
  4. Clamp small pieces when using a hacksaw, screwdriver, or soldering iron.
  5. Disconnect all electrical devices by pulling diectly on the plug, never the cord.
  6. When cutting the wire, always cut one wire at a time to avoid damaging the cutting tool.


  1. Always assume the soldering iron is hot.
  2. Always place the soldering iron in its holder when idling.
  3. Never shake excess solder off the tip.
  4. Never pass a soldering iron to another person; place it in the holder.
  5. Never solder on a circuit that has power applied to it.


  1. SEIRE OR SORT-sorting means to sort everything in each work area.
  2. SEITON OR SET – to organize , arrange and identify everything in work area for an efficient and effective and return of the irams in theei proper places.
  3. SEISO OR SWEEP- once you have everything in the work area sorted-up, clean-up, and organized, keep it that way
  4. SEIKETSO OR STANDARDIZE – to ensure that the first three steps in the 5S program are done effectively, the fourth step is to simplify and to standardize actions.
  5. SHITSUKE OR SUSTAIN – the final step is to continue the workers and maintaining the workplace standards.
