What are the potential hazards of using extension cords incorrectly?

Using extension cords incorrectly poses significant risks, including overheating, electrical shock, and fire hazards. When extension cords are not used as intended, they can carry more current than they are rated for, leading to excessive heat generation. This heat can damage the cord and any connected devices, potentially resulting in a fire.

Additionally, improper use, such as using cords that are frayed or damaged, or connecting multiple cords in a series, increases the likelihood of electrical shock. This is especially true in wet or damp environments where the risk of moisture interacting with electrical components is heightened. Proper awareness and training on extension cord usage are critical for ensuring safety and preventing these dangerous outcomes.

The other choices do not align with the primary safety concerns when dealing with extension cords and thus, do not accurately represent the potential hazards.
