In high-risk areas of the surgical suite, which electrical component must have ground fault interrupters and be explosion proof?

• A. Electrical outlet
• B. Light fixture
• C. Power strip
• D. Wall switch

Answer: (A)

Electrical safety in high-risk surgical areas hinges on components that prevent shock and ignition. Ground fault interrupters detect even tiny leakage of current from a device to ground and shut the circuit off within milliseconds, reducing the risk of patient or staff shock. Explosion-proof design helps prevent ignition of flammable anesthetic vapors if a fault occurs, by containing sparks or heat so they cannot ignite surrounding gases. The power-delivery point that connects all equipment—the electrical outlet—must be both GFCI-protected and explosion-proof because it directly interfaces with cords and plugs used for patient care devices. Other options like light fixtures, power strips, or wall switches do not routinely require or guarantee both protections in high-risk OR environments, and power strips are especially unsuitable due to their vulnerability and lack of adequate protection.
