Which type of hazard does a Ground Fault Circuit Interrupter (GFCI) protect against?

A Ground Fault Circuit Interrupter (GFCI) is specifically designed to enhance electrical safety by protecting individuals from electrical hazards, particularly those associated with ground faults. When a ground fault occurs, it means that electricity is escaping from its intended path and may pose a risk of electric shock or electrocution.

The GFCI detects these imbalances in electrical current and interrupts the circuit, effectively shutting off the power before harm can occur. This makes it essential in environments where moisture is present, such as kitchens and bathrooms, where the risk of electrical shock is heightened. The protective function of a GFCI is crucial for preventing accidents in these settings, reinforcing its role in safeguarding against electrical hazards.

Other hazards like mechanical, chemical, and biological hazards are not within the protective scope of a GFCI, as they pertain to different safety concerns that require alternative protective measures.
