What is a common fire hazard associated with electrical systems?

1. Properly grounded outlets

2. Exposed wires

3. Use of surge protectors

4. Use of extension cords

The correct answer is: Exposed wires

Exposed wires are a significant fire hazard because they can create a direct path for electricity that can lead to overheating, short circuits, and potentially igniting flammable materials nearby. When wires are not properly insulated or are damaged, they lose their ability to safely contain the electrical current. This increases the risk of sparks, which can ignite fires, especially in environments where combustible materials are present. In contrast, properly grounded outlets, the use of surge protectors, and extension cords, while they each have their limitations and appropriate usage guidelines, do not inherently present the same level of immediate danger as exposed wires. Proper grounding is intended to direct excess electricity safely to the ground, surge protectors provide a buffer against voltage spikes, and extension cords are safe when rated for the proper load and used appropriately. Hence, exposed wires represent a more direct and immediate fire hazard in electrical systems.
