1.4 Precautions
1.4
Ch.1
Precautions WARNING • An insufficiently reprocessed camera head may pose an infection control risk to the patients and/or operators who contact them. • The camera head reprocessor, light source, and/or front panels of equipment may cause an infection control risk. Perform proper cleaning and disinfection as described in their respective instruction manuals. A tap or basin that medical personnel come in contact with may cause an infection control risk as well. Perform proper replacement, cleaning, and disinfection. • All disinfection methods (whether performed manually or by an WD) and all sterilization methods (whether performed by low temperature or steam) require thorough prior cleaning of the instrument being reprocessed. If the equipment is not adequately cleaned prior to disinfection/sterilization, these processes will be ineffective. Immediately after each patient procedure and before disinfection/sterilization, thoroughly clean the camera head. • Residual disinfectant solution and detergent solution may cause adverse reactions in patients. Therefore, rinse all external surfaces of the camera head thoroughly with water to remove residual disinfectant solution and detergent solution after disinfection. • The results of sterilization depend on various factors. These factors include how the equipment was packaged, and the placing and loading of the package in the sterilization device. Verify the sterilization process using biological and/or chemical indicators. Follow the guidelines for sterilization issued by national authorities, professional organizations, and infection control professionals, including the frequency of the above verification, as well as the instruction manual for the sterilization device. • Establish an internal system of identifying contaminated versus reprocessed camera heads to prevent both mix-ups and cross-contamination. Some national or professional guidelines recommend separating dirty (contaminated) area, clean area, and storage area. Touching a reprocessed camera head with contaminated gloves or placing it on a contaminated hanger or surface, including letting it touch the floor, will recontaminate it. • Prior to each patient procedure, confirm that the camera head has been properly reprocessed and stored. If there are any doubts or questions, reprocess it again before the patient procedure, following the instructions given in this manual.

1.4 Precautions
Ch.1
WARNING • The accessory listed on the front cover of this manual is consumable, meaning that this accessory cannot be refurbished or repaired and is intended to be replaced once it shows any signs of wear and tear. Should any irregularity be observed, use a replacement accessory instead. Using a defective accessory may cause equipment malfunction, reduce the efficacy of reprocessing, present a risk to patients and/or operators, or damage the camera head and/or accessories. • Patient debris and used reprocessing chemicals pose infection control risks. To guard against contact with dangerous chemicals and potentially infectious material, wear appropriate personal protective equipment during reprocessing. Such protective equipment should include appropriate eyewear, face mask, cap, moisture-resistant clothing, shoe covers, and chemical-resistant gloves that fit properly and are long enough to prevent skin exposure. • The reprocessing room must be adequately ventilated to minimize the risks from chemical vapors. • Always remove contaminated personal protective equipment before leaving the reprocessing area to prevent contamination from spreading. • Only Olympus-recommended or Olympus-endorsed WDs have been validated by Olympus. When using a WD that is not recommended by Olympus, the manufacturer of the WD is responsible for validating compatibility of the WD with each Olympus camera head and accessory. • Only use the WD that meets the requirements of the relevant parts of ISO 15883 series. • Instructions provided in this manual are not valid for Olympus devices repaired by a non-Olympus facility. The Olympus recommended reprocessing procedures have not been validated for reprocessing devices repaired by a non-Olympus facility. In the event that your device has been repaired by a non-Olympus facility, it may pose an infection control risk to the patients and/or operators who contact them. • Prions, which are the pathogenic agents of the Creutzfeldt-Jakob disease (CJD), cannot be destroyed or inactivated by the reprocessing methods stated in this instruction manual. When using the camera head on patients with CJD or variant Creutzfeldt-Jakob disease (vCJD), be sure to use it for such patients only, or immediately dispose of it after use in an appropriate manner to prevent the usage of exposed devices on other patients.
