Which safety devices should be part of a hospital's electrical system?

The inclusion of circuit breakers and ground fault interrupters in a hospital's electrical system is crucial for a variety of safety reasons. Circuit breakers function as protective devices that automatically shut off electrical circuits in the event of an overload or short circuit, thus preventing potential electrical fires and equipment damage. This is particularly important in a hospital setting where sensitive medical equipment must remain operational and safe for patient care.

Ground fault interrupters (GFIs) serve a specialized function by detecting ground faults—conditions where electrical current escapes the intended path and could potentially cause a shock hazard. They quickly disconnect the power supply, significantly reducing the risk of electrical shock to patients and staff, especially in environments where water is present, such as bathrooms or surgical areas.

The combined effectiveness of circuit breakers and GFIs helps ensure compliance with electrical safety standards and protects both personnel and patients from electrical hazards, making them an essential part of a hospital's electrical system. The other options, while valuable in their own contexts, do not provide the same comprehensive level of safety and protection specific to the unique needs and vulnerabilities found in healthcare facilities.
