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 touch them.
• The endoscope reprocessor, video system center, light source, front panels of
equipment, and/or mouthpiece may cause an infection control risk. Perform proper
cleaning and 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 disinfection.
• All disinfection methods (whether performed manually or by an AER/WD), 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, including the instrument channel and the auxiliary
water channel, and all accessories used with the endoscope during the patient
procedure, such as all valves and the auxiliary water tube (MAJ-855), 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 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.
• 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 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.
• Do not use the AW channel cleaning adapter (MH-948) for patient procedures. It
will cause continuous insufflation and could result in patient injury.

1.4 Precautions
Ch.1
WARNING
• 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 combination cleaning brush
(BW-412T), 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. A damaged brush may break, which
can damage the endoscope or accessories.
• 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/WDs have been
validated by Olympus. When using an AER/WD that is not recommended by
Olympus, the manufacturer of the AER/WD is responsible for validating
compatibility of the AER/WD with each Olympus endoscope and accessory.
• Before using an AER/WD, confirm that it is capable of reprocessing the endoscope
including all channels and accessories. Be sure to attach all required
connectors/adapters. Otherwise, insufficient reprocessing may pose an infection
control risk. If you are uncertain as to the ability of your AER/WD to reprocess the
endoscope including all channels and accessories, contact the manufacturer of the
AER/WD for specific instructions and information on compatibility and the required
connectors/adapters.
• 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.

1.4 Precautions
Ch.1
WARNING
• 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, follow the respective guidelines in your country.
• 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
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.
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 0.5 MPa (5 kgf/cm2, 71 psig). Higher pressures may cause damage to
the endoscope.
