Electrical hazards are among the most serious risks in workplaces, especially in industries such as manufacturing, construction, mining, power generation, healthcare, and even offices. Electricity is indispensable for modern operations, yet it poses significant dangers including electric shock, burns, fires, explosions, and even death. In the context of Occupational Health and Safety (OHS), understanding the main causes of electrical hazards and implementing effective preventive measures is essential to protect workers, equipment, and property. The main causes of electrical hazards in workplaces can be enumerated as follows: One major cause is damaged or defective electrical equipment and wiring. Over time, insulation may crack, fray, or deteriorate due to heat, moisture, chemical exposure, mechanical stress, or aging. Exposed conductors increase the risk of electric shock and short circuits. Damaged cords, broken plugs, loose connections, and faulty switches are common sources of accidents. Another significant cause is improper installation of electrical systems. Electrical installations that do not comply with safety standards, codes, or specifications may result in overloading, short circuits, and grounding failures. Incorrect wiring, undersized conductors, and poor earthing systems can lead to overheating and fire hazards.
