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 it. • All disinfection methods and all sterilization methods 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 may cause adverse reactions in patients. Therefore, rinse all external surfaces of the camera head thoroughly with water to remove residual disinfectant 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. • 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.

1.4 Precautions
Ch.1
WARNING • 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. • 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. For methods to handle CJD, follow the respective guidelines in your country. • The camera head may be damaged by published methods for destroying or inactivating prions. For information on the durability of Olympus equipment against a particular reprocessing method, contact Olympus. In general, Olympus cannot guarantee the effectiveness, safety, and durability of reprocessing methods not described in this reprocessing manual. If you chose to use a reprocessing method not recommended in this manual, the local institution and/or physicians must assume responsibility for its safety and efficacy. Make sure to carefully inspect each piece of camera head’s equipment for irregularities (damage) prior to each patient procedure. Do not use the equipment if any irregularity is found. • Good quality control practices typically require appropriate documentation. Items such as local SOPs (Standard Operating Procedures), confirmation of operator training, routine testing of the disinfectant’s MEC (Minimal Effective Concentration), confirmation of the disinfectant’s use-life, etc. should be documented as performed. • Do not sterilize the camera head with ethylene oxide gas. It may pose an infection control risk to the patients and/or operators who get in contact with the camera head.

3.1
Compatibility summary
The camera head is compatible with several methods of reprocessing. However, not all reprocessing methods are compatible with all camera heads. Reprocessing with incompatible methods can cause equipment damage even if the number of reprocessing cycles is small. For appropriate reprocessing methods, see Table 3.1. Follow the policies at your local institution when choosing which methods listed in Table 3.1 to employ.
CAUTION • The methods listed as “compatible” in Table 3.1 are compatible for routine use only when used according to manufacturer’s instructions. Repeated use and reprocessing of camera heads leads to gradual wear and tear. Furthermore, reprocessing methods that employ higher temperatures and more caustic/corrosive materials may lead to faster deterioration. In general, sterilization processes are harsher on equipment than disinfection processes. Before each patient procedure, inspect the camera head for damage, according to the instructions described in this manual and its companion “OPERATION MANUAL”. • The instructions provided in this manual regarding material compatibility are not valid for Olympus devices repaired by a non-Olympus facility. Olympus repairs devices to manufacturer’s specifications using original equipment manufacturer’s (OEM) materials. The use of non-OEM materials to repair an Olympus device may affect the material compatibility of the device with certain reprocessing chemicals or methods. In the event that your device has been repaired by a non-Olympus facility, contact the repair facility for instructions regarding material compatibility. Olympus provides information regarding validated methods in terms of the following two criteria. Microbiological efficacy Material durability
