What type of electrical hazard does GFCI NOT protect against?

Ground Fault Circuit Interrupters (GFCI) are designed to protect against ground-fault hazards, which occur when electricity escapes the intended path and finds a ground connection through a person's body or other unintended pathway. GFCIs are crucial in areas where electrical circuits might come into contact with water—like bathrooms and kitchens—by detecting imbalances between the outgoing and incoming current.

While GFCIs can help reduce the risk of electrical fires primarily due to ground faults and unplugged devices, they do not specifically prevent electrical fires resulting from overloaded circuits or electrical equipment malfunctions. Additionally, they do not provide protection from line contact hazards, which involve direct contact with live electrical components, or overheating wires, problems often linked to faulty wiring and devices that are not directly related to ground faults.

Thus, the correct answer regarding what type of electrical hazard GFCIs do not protect against is line contact hazards. This highlights the importance of understanding different electrical safety devices and the specific protections they offer within a healthcare environment.
