16 Electrical Safety Tips for Working with Electricity

What are some general safety tips for working with or near electricity?

Inspect the portable cord, plug, extension cords, power bars, and electrical fittings connected to equipment for damage or wear before each use. If found defective replace the damaged equipment immediately. Electrical safety is very important while working with electricity.

Always tape extension cords to walls or floors when necessary. Do not use nails and staples because they may damage the insulation of extension cords and cause fire and shocks.
Do not use the under-rated extension board, switch socket, or plugs. Always use the extension cords or equipment that is rated for the level of amperage or wattage.

The fuses provide protection against short circuits. In case of insulation failure, the fuse blows and thus protects the man and machinery. Always use the correct size fuse. After blowing fuses, replace them with the correct size. Replacing a fuse with one of a larger size can cause excessive currents in the wiring and possibly start a fire.
If the extension cord or power socket is found hot during the use of electricity, immediately switch off the power and call a qualified electrician to check the system. Use the system after checking the power cord and power outlet.

The insulated ladder is useful in electrical work. If touches to live conductor, no electric current flows through the ladder. Therefore, always use ladders made with non-conductive side rails (e.g., fiberglass) when working with or near electricity or power lines.

After working for a few hours the Halogen lamp becomes hot. Therefore, always place halogen lights away from combustible materials such as clothes or curtains.
The risk of electric shock is greater in areas that are wet or damp. Install Ground Fault Circuit Interrupters (GFCIs) like ELCBs and RCBOs. These devices interrupt the electrical circuit before a current sufficient to cause death or serious injury occurs. A 30 mA sensitivity ELCB must be used for applications where there is a chance of leakage current.
Ground Fault Circuit Interrupter (GFCI) may be installed with portable electrical equipment for ensuring 100% safety against the leakage current.

Make sure that exposed receptacle boxes are made of non-conductive materials and are of IP67 protection class.
Know where the panel and circuit breakers are located in case of an emergency.
Label all circuit breakers and fuse boxes clearly. Each switch should be positively identified as to which outlet or appliance it is for.

Do not use outlets or cords that have exposed wiring. Use the proper plug and socket with the proper rating.
Do not hinder the accessibility of electrical panels.
In case of an electric shock, first, isolate the supply. Then, call a qualified person to check the system.
