Which area requires a hat and designated shoes for entry into the OR?

• A. Restricted area
• B. Unrestricted area
• C. Clean area
• D. Semi-restricted area

Answer: (A)

Controlling contamination in the operating room hinges on zone-specific attire. In the surgical suite, the restricted area is the space closest to the sterile field where access is limited to personnel wearing proper surgical attire. A hat and designated shoes are required here to prevent hair and street footwear from introducing contaminants into the sterile environment. The hat stops shedding hair and scalp particles, while designated shoes or covers keep dirt and organisms from being tracked into the OR. Because these safeguards are specifically tied to the restricted zone, this is the area that mandates head covering and OR footwear for entry. Other areas have looser or different requirements, such as general areas where basic hygiene suffices, and semi-restricted zones with some attire rules but not full restricted attire.
