OPERATION Important Sterilization Practices

Caution! Become familiar with the individual functions of the five (5) modes to ensure using proper sterilization cycle. Wrong mode selection or improper loading may result in improper sterilization.

• Do Not overload chamber. Refer to “Preparation and Loading”. Do not exceed maximum loading configuration. Otherwise, inadequate sterilization could result. • All functions of the sterilizer should be monitored to provide maximum sterility assurance. We recommend using Pelton & Crane’s printer to provide a permanent record of actual exposure times and temperatures. • For additional assurance that minimum sterilizing conditions have been achieved, good sterilization practices recommend the use of a quality temperature sensitive process indicator with each cycle and within each package. • Since temperature sensitive process indicators do not integrate sterilization parameters, biological monitoring is recommended to provide further information in detecting inadequate sterilizer performance. Biological indicators can be used to integrate the various cycle parameters and indicate whether sterilization conditions have been met in a particular cycle. • Thoroughly clean instruments before placing them in the sterilizer. Processing instruments with debris or blood contamination impedes sterilization and may result in staining and/or damage to instruments or sterilizer. Use no cleaners with chlorine. • Follow manufacturer’s recomendations for the individual items before sterilizing. • Use proper sterilization and instrument handling as recommended by ADA, CDC, AAMI, AORN and OSAP guidelines.

• Do Not use staples, pins or other devices which will puncture the packaging material as sterility may be compromised. • Do Not sterilize instruments while running cleaning cycle. • Sort instruments by type of metals. Do Not mix carbon steel stainless steel, brass, aluminum, chrome or other types of metals as plating may occur. • Place loose instruments on towel or absorbent paper. • Wrapped packages Must Not touch sides. • Place pouches with paper side down. • Place open containers tilting downward in tray. • Do Not attempt to sterilize long tubing as steam may not penetrate the full length. • Do Not wrap instruments too tightly. Inadequate sterilization may result from improper wrapping or placing too many instruments per package.

Sterilization Assurance Clinical Record Keeping • Review daily and weekly records to substantiate procedures taken to assure sterilization.

Techniques for Sterilization Assurance • Use internal sterilization process indicators inside all sterilizer loads to verify gross heat penetration. • Once per week, use a biological spore test indicator (BI) designed for gravity steam sterilizer operating at 121°C (Attest®, Biological Monitoring System, 3M, St. Paul, MN; or equivalent) or 134°C (EZ Test, Bozeman, MT) to test each type of cycle used at your facility. - Load sterilizer to maximum load used at your facility. - For “Wraps” and “Packs” Cycle, place biological indicator inside wrap or pack containing instruments and then place this pack or wrap in front lower tray of the sterilizer. (This is the cold spot, i.e. lowest temperature condition.) - For Unwrapped Cycle, load trays with instruments, place biological indicator in front lower tray of sterilizer.

CAUTION: ANY LIQUIDS THAT ARE STERILIZED IN THIS UNIT ARE FOR LABORATORY USE ONLY AND NOT FOR USE IN DIRECT PATIENT CONTACT.

Follow manufacturer’s instructions for using all test materials and maintaining good clinical records. • Follow Maintenance schedule on page 24 to ensure proper operation of the autoclave. • Note: Indicator tape should not be used as a sterilization indicator. It has a temperature sensitive stripe that changes color with temperature only.

OPERATION Preparation and Loading • Clean and dry items thoroughly. • Properly seal items in wrap or pouch if load is to be kept sterile during storage. Recommended wrap/ pouch materials are cloth, paper, or paper/poly pouches. Nylon pouches/tubing are not recommended. • This unit is not suitable for sterilization of gowns/ fabrics, “porous load”. • Place temperature sensitive process indicator inside package. • Place temperature sensitive indicator in front portion of bottom tray. • Place load on tray with space between instruments or packages so that steam can flow between items. • Place trays in chamber with adequate space for steam circulation.

The Following are recommended maximum loading configurations: Wrapped/Unwrapped Cycle • Model AE: Total weight not to exceed 1.5 lbs. This is equivalent to approximately 9 handpieces or hinged instruments (average weight of 2.3 ounces) or 30 hand instruments (average weight of 1 ounce.) • Model AF: Total weight not to exceed 2 lbs. This is equivalent to approximately 13 handpieces or hinged instruments (average weight of 2.3 ounces) or 42 hand instruments (average weight of 1 ounce.) Pack s Cycle NOTE: When calculating maximum load, use the same weight and instrument equivalencies as specified in the “Wrapped/ Unwrapped”cycle. • Model AE: Total weight not to exceed 2.5 lbs. One (1) pack in top tray and one (1) in bottom tray with pack dimensions not to exceed 5² x 7² x 1/4². • Model AF: Total weight not to exceed 2.5 lbs.. Two (2) packs in top tray and one (1) in bottom tray with pack dimensions not to exceed 5² x 7² x 1 1/2².

CAUTION: ANY LIQUIDS THAT ARE STERILIZED IN THIS UNIT ARE FOR LABORATORY USE ONLY AND NOT FOR USE IN DIRECT PATIENT CONTACT.
