To identify possible electrical hazards in the workplace, the NSC recommends the following nine steps:
· Check the surrounding area for spills, dampness or water.
· Check connections and ground wires are tight and free from breaks.
· Check circuits and wiring are in good repair and not overloaded.
· Check insulation for worn spots or breaks that could cause a shock.
· Check the condition of cords and extension cords.
· Check and maintain equipment to make sure it is working right and free of defects or damage
· Check equipment belts and gears to detect excess tension or binding that can cause a power overload.
· Check that personal hand and foot protectors are kept in good repair and readily available.
· Immediately report any hazards, damage and defective equipment, tools and machinery to a supervisor or manager.
