Techniques of Sterilization

Operator Manual

P129394-176

4.1  General

The information in this section is intended as a general guide to
steam sterilization techniques. Also recommended is reference to
the standards of the Association for the Advancement of Medical
Instrumentation (AAMI ST-46), Steam Sterilization and Sterility
Assurance, 3rd Edition.

•

Prior to sterilization, all materials and articles must be thoroughly
cleaned. 

•

After sterilization, goods should be stored in conditions that will
not compromise the barrier quality of their wrapping materials. 

Important: 

Applicable cycles have been validated to satisfy the

requirements outlined in 

Table 4-1

 and 

Table 4-2

. If cycle

parameters (sterilize time, dry time, temperature) other than those
listed are required, it is the responsibility of the healthcare facility to
consult and follow the device manufacturer’s written instructions. 

NOTE: 

Contact STERIS

®

 for information on a wide range of

education/ training programs designed to meet the educational needs
of healthcare industries.

As part of the operator’s verification of the sterilization process,
biological indicators may be used to demonstrate that sterilization
conditions have been met.

NOTE: 

Contact STERIS for information on specific biological

indicators recommended for use with this sterilizer. 

WARNING: The liquid cycle is 
for non-patient contact use 
only.
