Sterilization Monitoring Guidelines

Note

The information below is provided for reference only. Contact appropriate state / local agencies for
specific sterilization guidelines for your office. Additional information on infection control is available
from the Centers for Disease Control and Prevention (CDC), Organization for Safety and Asepsis
Procedures (OSAP), and the American Dental Association (ADA).

Physical Monitors

Temperature and pressure measuring devices can help detect sterilizer malfunctions.
The sterilizer’s control system aborts the cycle and displays a message if physical conditions go
outside established limits. The optional printer can be used to create a record of each load’s actual
cycle time, temperature, and pressure.

Note

Use only FDA cleared chemical & biological indicators designed for steam sterilization that are
compatible with the particular sterilization cycle temperature and exposure time being monitored.
Use sterility monitors with each sterilization load. If a sterilization cycle is terminated prematurely,
reprocess instruments to ensure sterility of the load. Process the load according to your regular
practice, placing indicators near the handle side of tray. Follow manufacturer’s instructions for
proper disposal of used indicators.

Chemical Indicators

Chemical indicators are designed to verify that conditions in the sterilizer chamber were adequate to
achieve sterilization. They do not validate that a processed item is sterile. If a chemical indicator shows
a failure, items in that load are considered non-sterile. Potential causes for sterilization failures include:

improper cleaning, packing, loading, or a sterilizer malfunction. Determine the cause of any sterilization
failure, and remedy the situation before running the next cycle. Only FDA cleared chemical indicators
labeled for use with the nontraditional steam sterilization cycle parameters, e.g. temperature and exposure

time, of the M3 Sterilizer should be used for monitoring the three M3 UltraFast® cycles. Follow the chemical

indicator’s instructions for proper storage, use, interpretation, and disposal.

Biological Indicators

Biological indicators are microbiological devices designed to accompany items being sterilized to monitor
adequacy of the sterilization process. If a biological indicator shows a failure, items in that load are
considered non-sterile. Potential causes for sterilization failures include: improper cleaning, packing,
loading, or a sterilizer malfunction. Determine the cause of any sterilization failure, and remedy the
situation before running the next cycle. Only FDA cleared biological indicators labeled for use with the
nontraditional steam sterilization cycle parameters, e.g. temperature and exposure time, of the M3 Sterilizer

should be used for monitoring the three M3 UltraFast® cycles. Follow the biological indicator’s instructions

for proper storage, use, interpretation, and disposal.

Loading the Tray

Types of Items

Before placing any instrument in the M3 UltraFast®,
check with the instrument manufacturer to be sure the
materials are compatible with steam sterilization, and
to verify the acceptability of sterilization parameters.

The M3 is designed to sterilize the following:

• High & low speed handpieces

• Metal instruments

• Rubber / plastic devices (ex. suction cannulas, impression trays, etc.)

• Wrapping / bundling materials (ex. CSR wrap, instrument pouches, etc.)

• Cassettes (Hu-Friedy Signa-Stat [6.5” x 10.5” x 1.25”] or smaller)

• Surgical instruments (ex. ophthalmologic instruments)

Equipment Alert

Do not sterilize items composed of any of the following materials in the M3:

• Corrosion sensitive metal (ex. carbon steel, iron, etc.)

• Fragile items susceptible to breaking under pressure / high temperature

• Liquids

• Biomedical waste

• Textiles (including towels, gauze, etc.)

• Plastics that may break down or produce residue when exposed to

steam / high temperatures.
Examples
Polyethylene Styrene Cellulosics ABS
PVC Textiles Acrylic (Plexiglass™)
PPO (Noryl™) Latex Neoprene

Qualication Testing

Your sterilizer should be tested after sterilizer installation, malfunctions, relocation, major repairs, and
after sterilization process failure. Qualication testing should be performed prior to placing the sterilizer in
service. If multiple cycles types are used, e.g. “Pouches” and “Low Temp” each cycle type should be
qualied. Qualication testing should include at least one Biological Indicator (BI) (sometimes referred to as
Spore Tests) and one Chemical Indicator (CI). The test pack should be performed with items routinely
processed and considered to be the most difcult to sterilize. Additional items should be placed in the
chamber along with the Biological Indicator and Chemical Indicator so that chamber is fully loaded (don’t
exceed the maximum capacities listed in the tables under “Guidelines for Loading” in this manual). Three
consecutive test runs, for each cycle type tested, with negative results from the BIs, and the appropriate
readings from all physical monitors and chemical indicators demonstrating complete sterilization, provide
verication that the sterilizer has been properly installed (or reinstalled after relocation) or repaired to the
manufacturer’s specications and that it will function effectively in the facility in which it is installed. All items
processed during qualication testing should be quarantined until the results of the biological testing for all

three test runs are available.

003-1658-00 © Midmark Corporation 2015

Pouching and Wrapping Items

The M3 is capable of sterilizing pouched or wrapped items.

• When pouching or wrapping items, use only sterilizer pouches and wraps that have
been cleared by the FDA and labeled for use with the nontraditional steam sterilization
cycle parameters, e.g. temperature and exposure time, of the M3 sterilizer. Follow the

manufacturer’s instructions for use.

• When using cassettes in the M3 follow the manufacturer’s instructions for use.

• Pouched items to be sterilized should be placed lengthwise with plastic side of
pouch facing up in the M3 UltraFast® tray.
The pouches may overlap slightly, but items must not be layered. Refer to diagram below.

Loading the Tray - continued

Caution

Failure to comply with these guideline may adversely affect sterilization and/or drying.

Immediate Use Sterilization

The M3 is capable of immediate use sterilization - sterilizing unwrapped instruments for immediate use.
Please consider the following when choosing whether or not to sterilize your instruments unwrapped:

• The sterility of unwrapped instruments is compromised upon exposure to a non-sterile
environment. Follow CDC guidelines for using unwrapped, sterilized instruments.

• Due to the sensitive nature of some types of surgery (including, but not limited to
ophthalmological), instruments used in such procedures must be wrapped or pouched
in order to reduce their exposure to sterilization process residues. The water reservoir
should also be drained and relled with fresh distilled water on a daily basis when
processing instruments for these procedures on a routine basis.

Extended Use Maintenance

The M3 is designed and tested to provide exceptional reliability throughout its service life. However, like
all electro-mechanical devices it is subject to wear and degradation with use.

To ensure the integrity, performance, and safety of all major components it is the responsibility of the user
to have the sterilizer performance / operation veried by a Midmark Authorized Service Provider after
8 years or 20,000 cycles of use, whichever comes rst. After 8 years or 20,000 cycles of use an annual
inspection by a Midmark Authorized Service Provider is recommended.
