A hospital-grade receptacle is typically indicated by which feature?

• A. Red dot
• B. Blue stripe
• C. Yellow label
• D. Green dot

Answer: (D)

A hospital-grade outlet is identified by a green dot on the receptacle. This green marking signals that the outlet meets stricter safety and durability standards used in healthcare environments, making it suitable for frequent use and thorough cleaning. The other colors—red dot, blue stripe, yellow label—are not the standard indicators for hospital-grade in most practices, so they don’t reliably signify the same level of reliability and certification.
