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, 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 AER/WD) and all sterilization methods (whether performed by steam or hydrogen peroxide) 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. • The channel of the endoscope and all accessories used with the endoscope during the patient procedure must be reprocessed after each patient procedure, even if the channel 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 detergent solution and disinfectant solution may cause adverse reactions in patients. Therefore, rinse all external surfaces and the channel of the endoscope and accessories thoroughly with water to remove residual detergent solution following cleaning and residual disinfectant solution following 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 endoscopes and accessories 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 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.

1.4 Precautions
Ch.1
WARNING • 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 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. • Single-use brushes, such as the single use single-ended cleaning brush (BW-400B) and the single use combination cleaning brush (BW-411B), are 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.
