Which factor can commonly lead to electrical fires?

Old or faulty wiring is a significant factor that can commonly lead to electrical fires. Over time, wiring can deteriorate due to wear and tear, exposure to environmental elements, or substandard installation. This deterioration can create short circuits or overloads, leading to overheating of the wires. When wires become frayed or damaged, they can expose metal conductors that pose a risk of sparking or creating contact with flammable materials, greatly increasing the likelihood of fire.

In healthcare settings, where electrical devices and equipment are in constant use, old or faulty wiring can contribute to dangerous situations if not properly maintained or replaced. Regular inspections and adherence to safety standards are crucial in preventing these types of hazards, as outdated wiring systems may not have the capability to handle the electrical loads required by modern medical equipment.
