What are common causes of injury from electricity?
Some of the causes of electric shock include:
- Faulty appliances.
- Damaged or frayed cords or extension leads.
- Electrical appliances coming in contact with water.
- Incorrect or deteriorated household wiring.
- Downed powerlines.
- Lightning strike.
Electricity-related hazards include electric shock and burns, arc-flash burns, arc-blast impacts, and falls. Electric shock and burns. An electric shock occurs when electric current passes through your body. This can happen when you touch an energized part.
In which circumstances are contact with electricity most likely to be harmful?
The risk of electric shock is greater in certain working conditions, for example wet areas. Accidents frequently involve the use of electrical appliances and tools, and unauthorized work on the electrical equipment of machinery and fixed electrical installations.
