Sterilization
ETO gas sterilization
As an alternative to high-level disinfection, the endoscope can be sterilized by
ethylene oxide (ETO) gas. After performing manual cleaning and drying as
described in Section 3.3, “Precleaning” and Section 3.5, “Manual cleaning”,
follow the procedures given below.
• Exceeding the recommended parameters may cause
equipment damage.
• If ETO gas sterilization is performed while the water-resistant
cap is attached, the covering of the bending section can be
damaged.
• The chain for water-resistant cap (MAJ-1119) and the
water-resistant cap itself (MH-553) cannot be sterilized by
ETO gas and may be damaged if they are subjected to ETO
gas sterilization.
1.
Dry the endoscope and all equipment before ETO gas sterilization.
2.
Remove the water-resistant cap before ETO gas sterilization (see Figure
3.34). If the water-resistant cap is connected to the endoscope using the
chain, be sure to remove the chain for water-resistant cap and
water-resistant cap from the endoscope before proceeding to ETO gas
sterilization.

Seal the instrument in a package appropriate for ETO gas sterilization
according to your hospital’s protocol.
