Techniques of Sterilization

Operator Manual

P129394-068

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-79, comprehensive guide to steam
sterilization and sterility assurance in health care facilities).

•

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 1

 (page ii). 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 Corporation 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: It is inappropriate 
for a healthcare facility to 
sterilize liquids for direct 
patient contact.
