1.4 Precautions
Chapter 1 General Policy
• An insufficiently cleaned, disinfected, or sterilized endoscope
and/or accessories may pose an infection control risk to the
patients and/or operators who contact them.
• All disinfection methods (whether performed manually or by
an automated endoscope reprocessor), and all sterilization
methods (whether performed by ethylene oxide gas or
steam) require thorough prior cleaning of the instrument
being reprocessed. If the equipment is 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 all accessories used with the endoscope during
the patient procedure, such as all valves, must be cleaned
and high-level disinfected or sterilized after each patient
procedure, even if the channels or accessories were not
used during the patient procedure. Insufficient cleaning and
disinfection or sterilization of these components may pose an
infection control risk to patients and/or operators.
• Disinfectant solutions are hazardous. After disinfection, rinse
all external surfaces and channels of the endoscope and
accessories thoroughly with water to remove residual
disinfectant solution.
• 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, as well as the instruction
manual for the sterilization device.

Chapter 1 General Policy
Leakage tester
• Establish an internal system of identifying contaminated
versus reprocessed endoscopes and accessories to prevent
both mix-ups and cross-contamination. 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.

• 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.
EVIS EXERA II TJF TYPE Q180V REPROCESSING MANUAL
Chapter 1 General Policy
AW channel cleaning
adapter (MH-948)
• Do not use the AW channel cleaning adapter (MH-948) for
patient procedures. It will cause continuous insufflation and
could result in patient injury.
Figure 1.2
• The accessories listed on the front cover of this manual are
consumables, meaning that these accessories cannot be
refurbished or repaired and are intended to be replaced once
they show any signs of wear. 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 channel cleaning
brush (BW-201T), the single use combination cleaning brush
(BW-412T), the single use channel-opening cleaning brush
(MAJ-1339), and the single use soft brush (MAJ-1888), 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 endoscope and/or accessory damage.

Chapter 1 General Policy
• Patient debris and reprocessing chemicals are hazardous.
To guard against contact with dangerous chemicals and
potentially infectious material, wear appropriate personal
protective equipment during cleaning, disinfection, and
sterilization. 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.
Adequate ventilation protects against the buildup of toxic
chemical fumes.
• Always remove contaminated personal protective equipment
before leaving the reprocessing area to prevent
contamination from spreading.
• Only Olympus-recommended or Olympus-endorsed
automated endoscope reprocessors (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 and accessory.
• Before using an AER, confirm that it is capable of
reprocessing the endoscope including all channels, the
forceps elevator recess, 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, the forceps elevator recess, and accessories,
contact the manufacturer of the AER for specific instructions
and information on compatibility and required connectors.
When you use an AER which allows you skip some steps in
precleaning and manual cleaning of endoscopes, confirm
with the AER manufacturer that such skip is applicable to this
endoscope and establish detailed precleaning and manual
cleaning procedures of this endoscope according to both
instructions of this manual and the AER manufacturer.
• Put the forceps elevator in intermediate position of the range
of movement by turning the elevator control lever and set it in
your AER.

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 cleaning, disinfection, or sterilization methods
not described in this reprocessing manual. If you chose 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.

sterile packaging and wraps according to national guidelines.
Chapter 1 General Policy
1.7 Reprocessing before patient procedure
• Improper storage practices, such as not thoroughly drying
external and internal surfaces (lumens) including the forceps
elevator recess prior to storage, will lead to an infection
control risk.
• Improper handling, such as touching a reprocessed
endoscope and/or accessories with contaminated gloves,
placing a reprocessed device on a contaminated hanger or
surface, allowing devices to touch the floor, etc., will
recontaminate the device.
Some national or professional guidelines recommend
reprocessing endoscopes prior to their first use of the day.
Confirm that the endoscope and accessories have undergone proper
reprocessing following their last use and that they have been stored properly.
Check the storage period of reprocessed endoscopes, and check for surface
