Page 21: Preparation Before Sterilization
PREPARATION BEFORE STERILIZATION The purpose of packaging and wrapping items for sterilization is to provide an effective barrier against contamination during storage, once the items have been sterilized. VERY IMPORTANT! When sterilizing cotton wool or pads, it is essential to wrap them in paper or cotton bags in order to prevent the multi-purpose valve and the autoclave openings from becoming clogged with remnants of the material. - Page 22 Pouch Rack It is recommended that a Tuttnauer Pouch Rack be used. This will allow the operator to place pouches on their side, which will increase capacity and will allow for better exposure to steam for sterilization and better circulation of air for drying.
- Page 23 24. If spotting is detected on the instruments the first step would be to use an ordinary eraser to remove the spot. If there is no pitting under the spot then the spot was only dirt. Dirt spots on an instrument may be an indication that the autoclave needs to be cleaned or that the instruments were not adequately cleaned or dried.
