List the common electrical hazards that can happen in a domestic circuit.

Hint: An electrical hazard is a potentially unsafe situation in which a worker comes into contact with energized machinery or a conductor. The worker may suffer a shock injury as a result of the contact, and he or she may also sustain an arc flash (electrical explosion) burn, a thermal burn, or a blast injury.

Complete step-by-step solution:
Here is some listing of some electrical hazard that could occurred in a domestic circuit:
1. POOR WIRING AND DEFECTIVE ELECTRIC WIRES:
For safety, high-quality wiring that meets safety requirements is important. Fire, power surges, arc faults, and other severe effects may all be caused by poor wiring. As a result, it's always better to avoid do-it-yourself electrical work and instead hire a licensed electrician to wire your home.
2. Circuits Close to Water:
Water outlets in toilets, kitchens, and other living areas should be located a long way from the water supply. Electricity conducts by water, so holding outlets away from it decreases the risk of electric shock. In the bath, near the pool, or anywhere with a wet surface, never use a radio, hair dryer, phone, or other gadget.
3. Wet Hands:
Electrical appliances should never be handled with wet hands as this heightens the chance of getting an electric shock.
4. Properly Covered Electrical wires:
Heavy covering of wires can cause the cords to overheat, which could lead to an electrical fire. Keep cords and wires away from other items and keep them uncovered. Similarly, make sure that items like computers and televisions have enough space around them for ventilation, to prevent them from overheating.

Note: When using extension cords, tape them to the wall or the floor. Nails and staples can damage extension cords and cause fires and electric shocks. Use extension cords or devices rated for the amount of amperage or wattage you'll be using. Always use the appropriate fuse size.
