Instruments and materials that penetrate the skin, mucous membranes, or bone; these items must be sterile before use. Critical Items
Instruments, equipment, or materials that frequently contact mucous membranes, but cannot be sterilized because of their design or inability to withstand heat. Semi-Critical Items
