1.4 Precautions

1.4

Ch.1

Precautions WARNING • An insufficiently reprocessed endoscope and/or accessory may pose an infection control risk to the patients and/or operators who contact them. • The endoscope reprocessor, video system center, light source, and/or front panels of equipment may cause an infection control risk. Perform proper cleaning and/or disinfection as described in their respective instruction manuals. A tap, basin, and/or nozzle of pharyngeal anesthetic spray that medical personnel come in contact with may cause an infection control risk as well. Perform proper replacement, cleaning, and/or disinfection. • All disinfection methods (whether performed manually or by an AER) and all sterilization methods (whether performed by ethylene oxide gas or steam) require thorough prior cleaning of the instruments being reprocessed. If the instruments are not adequately cleaned prior to disinfection/sterilization, these processes will be ineffective. Immediately after each patient procedure and before disinfection/sterilization, thoroughly clean the endoscope and the accessories used with the endoscope. • All channels of the endoscope and all accessories used with the endoscope during the patient procedure must be reprocessed after each patient procedure, even if the channels or accessories were not used during the patient procedure. Insufficient reprocessing of these components may pose an infection control risk to patients and/or operators. • Residual disinfectant solution and detergent solution may cause adverse reactions in patients. Therefore, rinse all external surfaces and channels of the endoscope and accessories thoroughly with water to remove residual disinfectant solution following disinfection and detergent solution following cleaning. • 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.

1.4 Precautions

Ch.1

WARNING • Establish an internal system of identifying contaminated versus reprocessed endoscopes and accessories to prevent both mix-ups and cross-contamination. Some national or professional guidelines recommend separating the dirty (contaminated) area, clean area, and storage area. Touching a reprocessed endoscope and/or accessories with contaminated gloves or placing them on a contaminated hanger or surface, including letting them touch the floor, will recontaminate them. • Prior to each patient procedure, confirm that the endoscope and accessories have been properly reprocessed and stored. If there are any doubts or questions, reprocess them again before the patient procedure, following the instructions given in this manual. • Perform a leakage test on the endoscope after each precleaning procedure. 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. Use of a leaking endoscope may also pose an infection control risk. Leakage tester

Figure 1.1 • Store alcohol in an airtight container. Alcohol stored in an open container may cause a fire hazard and may result in a loss of efficacy due to evaporation. • The accessories listed on the front cover of this manual cannot be refurbished or repaired and are intended to be replaced once they show any signs of wear and tear. Should any irregularity be observed, use a replacement accessory instead. Using defective accessories may cause equipment malfunction, reduce the efficacy of reprocessing, present a risk to patients and/or operators, or damage the endoscope and/or accessories.

1.4 Precautions

Ch.1

WARNING • Single-use brush, such as the single use combination cleaning brush (BW-411B), is designed for cleaning only one endoscope and its related accessories. Dispose of the single-use brush immediately after use. Using a single-use brush to clean multiple endoscopes and/or accessories may reduce its cleaning efficacy and may damage the brush leading to brush breakage or the endoscope and/or accessory damage. • 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 AERs have been validated by Olympus. When using an AER that is not recommended by Olympus, the manufacturer of the AER is responsible for validating compatibility of the AER with each Olympus endoscope, accessories and medical instruments. • Only use the AER/WD that meets the requirements of the relevant parts of EN ISO 15883 series in the member states of the EU. • Before using an AER, confirm that it is capable of reprocessing the endoscope including all channels and accessories. Be sure to attach all required connectors. Otherwise, insufficient reprocessing may pose an infection control risk. If you are uncertain as to the ability of your AER to reprocess the endoscope including all channels and accessories, contact the manufacturer of the AER for specific instructions and information on compatibility and required connectors. • The 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, contact the repair facility for instructions regarding reprocessing. • 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 endoscope and accessories on patients with CJD or variant Creutzfeldt-Jakob disease (vCJD), be sure to use them for such patients only, or immediately dispose of them after use in an appropriate manner to prevent the usage of exposed devices on other patients. For methods to handle CJD/vCJD, follow the respective guidelines in your country.

1.4 Precautions

Ch.1

WARNING • The endoscope and accessories 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 choose 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 endoscopic equipment for irregularities (damage) prior to each patient procedure. Do not use the equipment if any irregularity is observed. • 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. • In case of performing any microbial test or other test using extraction fluid on the reprocessed endoscope, the reprocessing process has to be performed again according to the “REPROCESSING MANUAL” before patient procedure. • In case of performing any microbial test or other test using extraction fluid on the reprocessed endoscope, the reprocessing process has to be performed again according to the “REPROCESSING MANUAL” before patient procedure.

CAUTION • Before immersing the endoscope in reprocessing fluids, confirm that the ETO cap (MB-156) is not attached to the endoscope. If the ETO cap is attached, the reprocessing fluids will be able to penetrate the inside of the endoscope, and it can be damaged. • When aerating or irrigating the endoscope channels, the air or water pressure must not exceed 0.3 MPa (3 kgf/cm2, 43 psig). Higher pressures may cause damage to the endoscope. • Store spare accessories in their original packaging to prevent damage. • To prevent damage, do not apply excessive force to the endoscope and accessories during reprocessing. • Vapors from disinfectant solution and alcohol may damage electronic devices such as computers. Properly manage the quality and durability of the devices used in reprocessing rooms and the ventilation performance of the rooms.
