Which item is an example of a noncritical item?

• A. Manicure implements
• B. Sterile needle
• C. Towels
• D. Client chair

Answer: (D)

Noncritical items are those that only touch intact skin and do not contact mucous membranes or penetrate the body. They require cleaning and low-level disinfection, not sterilization. The client chair fits this category best because it mainly contacts the client’s intact skin and clothing and doesn’t touch mucous membranes or penetrate the skin, so it’s treated as a noncritical surface between clients. By comparison, a needle would be considered critical since it enters sterile tissues. Towels and manicure implements are also noncritical in many settings, but the chair is the clearest example of a noncritical surface in a salon context.
