  • Page 39: Preparation Before Sterilization

    10 PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping of items for sterilization is to provide an effective barrier against sources of potential contamination in order to maintain sterility and to permit aseptic removal of the contents of the pack. Packaging and wrapping materials should permit the removal of air from the pack, penetration of the sterilizing water vapor into the pack and removal of the sterilizing vapor.
  • Page 40 All instruments must be sterilized in an open position. Use single-use wraps only once and discards them after use. Place a sterilization indicator strip in each tray. Place instruments with ratchets opened and unlocked or clipped on the first ratchet position. Disassemble or sufficiently loosen multiple-part instruments prior to packaging to permit the sterilizing agent to come into contact with all parts of the instrument.
