The semi-restricted area is a designated space in the operating room environment where specific protocols regarding attire must be followed. In this area, surgical staff is required to wear scrub attire and head coverings to maintain a sterile environment and minimize contamination risks. This area typically includes places such as the hall leading to the operating rooms or areas where sterile supplies are stored but do not require full sterile gowning.

The purpose of requiring scrub attire and head coverings in the semi-restricted area is to ensure hygiene and safety while still allowing access to supplies and instruments needed for surgery. It is essential for preventing the transmission of microorganisms, thereby protecting both the patients and surgical staff. Proper attire serves as a barrier against contaminants, which is critical not only in the operating room but also in adjacent support areas.

In contrast, the restricted area refers to the actual operating room where a higher level of sterility is required, necessitating the use of additional barriers such as gowns, gloves, and masks for anyone entering the space. The clean area might refer to places where sterile equipment and instruments are prepared but does not carry the same strict attire requirements. The waiting area is designated for family and friends of patients and does not require any specific attire related to surgical procedures.
