Precautions •
Some endoscope reprocessors are not designed to reprocess an elevator wire channel. When using one of these endoscope reprocessors, the elevator wire channel must be reprocessed manually as described in Chapter 3.
•
Failure to properly clean and high-level disinfect or sterilize endoscopic equipment after each examination can compromise patient safety. During use, the instrument normally comes in contact with intact mucous membranes. To minimize the risk of transmitting diseases from one patient to another, after each examination the endoscope must undergo thorough manual cleaning followed by high-level disinfection or sterilization after each examination.
•
ALL channels of the endoscope, including elevator wire channel where fitted, 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 or organic material that could reduce the efficacy of disinfection or sterilization.
•
Olympus confirms validation of the endoscope reprocessors recommended by Olympus only. If using endoscope reprocessor that are not recommended by Olympus, the endoscope reprocessor manufacturers are responsible for validation of the endoscope reprocessor with the endoscope models listed in its intended use statement. If using an endoscope reprocessor, confirm that it is capable of reprocessing endoscope including all channels. If there are channels and/or other parts which cannot be cleaned and high-level disinfected by the endoscope reprocessor, have to undergo manual cleaning and high-level disinfection or sterilization as described in Chapter 3, “Cleaning, Disinfection and Sterilization Procedures” after using the endoscope reprocessor. 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 you are uncertain as to the ability of your endoscope reprocessor to clean and high-level disinfect endoscope including all channels, contact the endoscope reprocessor supplier for specific instructions and/or connectors.
•
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 eye wear, face mask, moisture-resistant clothing and chemical-resistant that fit properly and are long enough so that your skin is not exposed. Always remove contaminated protective clothing before leaving the cleaning area.
•
Thoroughly rinse off the disinfectant solution. Rinse the outer surface of the endoscope, channels and cleaning equipment thoroughly with water to remove the disinfectant solution residue.
•
The disinfection/sterilization room must be adequately ventilated. Adequate ventilation protects against toxic chemical fumes.
