Precautions •
Failure to properly clean and high-level disinfect or sterilize endoscopic equipment after each procedure may compromise patient safety. To minimize the risk of transmitting diseases from one patient to another, after each procedure the endoscope and its ancillary equipment must undergo thorough manual cleaning followed by high-level disinfection or sterilization as described in Chapter 3, “Cleaning, Disinfection, and Sterilization Procedures”. Reprocess not only the external surface of the endoscope but also all channels.
•
ALL channels of the endoscope, including the auxiliary water channel (where existing), MUST be cleaned and high-level disinfected or sterilized during EVERY reprocessing cycle, even if the channels were not used during the previous patient procedure. Otherwise, insufficient cleaning and disinfection or sterilization of the endoscope may pose an infection control risk to the patient and/or operators performing the next procedure with the endoscope.

•
If the endoscope is not cleaned meticulously, effective disinfection or sterilization may not be possible. Clean the endoscope and accessories thoroughly before disinfection or sterilization to remove microorganisms and organic material that could reduce the efficacy of disinfection or sterilization.
•
Olympus only confirms validation of the endoscope reprocessors it recommends. When using an endoscope reprocessor that is not recommended by Olympus, the manufacturer of the endoscope reprocessor is responsible for validating compatibility of the reprocessor with the endoscope models listed in its instruction manual.
•
Before using an endoscope reprocessor, confirm that it is capable of reprocessing the endoscope, including all channels. If you are uncertain as to the ability of your endoscope reprocessor to clean and high-level disinfect the endoscope, including all channels, contact the endoscope reprocessor’s manufacturer for specific instructions and/or information on connectors. Insufficient cleaning and disinfection or sterilization of the endoscope may pose an infection control risk to the patient and/or operators performing the next procedure with the endoscope.
•
Patient debris and reprocessing chemicals are hazardous. Wear personal protective equipment to guard against dangerous chemicals and potentially infectious material. During cleaning and disinfection or sterilization, wear appropriate personal protective equipment, such as eyewear, face mask, moisture-resistant clothing, and chemical-resistant gloves that fit properly and are long enough so that your skin is not exposed. Always remove contaminated personal protective equipment before leaving the reprocessing area.
•
Thoroughly rinse off the disinfectant solution. Rinse the external surface of the endoscope, all channels, and the reprocessing equipment thoroughly with water to remove any disinfectant solution residue.
•
The disinfection/sterilization room must be adequately ventilated. Adequate ventilation protects against the buildup of toxic chemical fumes.
•
Store alcohol in an airtight container. Alcohol stored in an open container is a fire hazard and will result in a loss of efficacy due to evaporation.

Chapter 1 General Policy
•
Be sure to perform a leakage test on the endoscope prior to manual cleaning. Do not use the endoscope if a leak is detected. Use of an endoscope with a leak may cause a sudden loss of the endoscopic image, damage to the bending mechanism, or other malfunctions.
•
Prior to each procedure, confirm that the endoscope has undergone proper cleaning, disinfection, and sterilization. If it is determined that the endoscope has not been properly reprocessed, reprocess it again following the instructions given in this manual.
•
With the cleaning, disinfection, and sterilization methods stated in this instruction manual, prions, which are the pathogenic agent of Creutzfeldt-Jakob disease (CJD) cannot be destroyed or inactivated. When using this instrument on a patient with CJD or variant Creutzfeldt-Jakob disease (vCJD), be sure to use this product for such patient only and/or immediately dispose of this product after use in an appropriate manner. For methods to handle CJD, please follow the respective guidelines in your country.
•
This instrument may not be durable, or may not have sufficient durability against the respective methods stated in the guidelines of each country for removing or inactivating prions. For information on the durability against each method, please contact Olympus. If cleaning, disinfection, and sterilization methods not stated in this instruction manual are performed, Olympus cannot guarantee the effectiveness, safety and durability of this instrument. Be sure to confirm that there is no irregularity before use, and use under responsibility of a physician. Do not use if any irregularity is observed.
•
When aerating or irrigating the endoscope channels, the air or water pressure must not exceed 0.5 MPa (5 kgf/cm2, 71 psig). Higher pressures may cause damage to the endoscope.
•
When reprocessing an endoscope that has a flexibility adjustment mechanism, make sure that the insertion section is set to its most flexible condition (indicated by the “z” mark on the flexibility adjustment ring). If the endoscope is cleaned and disinfected or sterilized while the insertion section is too rigid, the endoscope may be damaged (for endoscopes with flexibility adjustment only).

2.3
Disinfectant solution In the U.S., agents used to achieve high-level disinfection are defined as liquid chemical germicides registered with the U.S. Food and Drug Administration as “sterilant/disinfectants” that are used according to the time, temperature, and dilution recommended by the disinfectant manufacturer for achieving high-level disinfection. These conditions usually coincide with those recommended by the disinfectant manufacturer for 100% kill of mycobacterium tuberculosis. In general, 2 – 3.5% glutaraldehyde solutions, when used according to the manufacturer’s instructions for achieving high-level disinfection, are compatible with Olympus endoscopes. If the disinfectant solution is reused, routinely check its efficacy with a test strip according to the manufacturer’s recommendations. Do not use solutions beyond their expiration date.
For further information regarding the compatibility of glutaraldehyde-based or nonglutaraldehyde-based disinfectant solutions, contact your local Olympus organization.
2.4
Rinse water Once removed from disinfectant solution, the instrument must be thoroughly rinsed with sterile water to remove any disinfectant residue. If sterile water is not available, clean, potable tap water or water that has been processed (e.g., filtered) to improve its microbiological quality may be used. When nonsterile water is used after disinfection, wipe the endoscope and flush the channels with 70% ethyl or isopropyl alcohol, then air-dry all internal channels to inhibit the growth of bacteria. Do not reuse rinse water.
