USING THE STERILIZER - 5
5.4 Preparing the material before sterilization
5.4.1 Preliminary operations
All the material to be prepared for sterilization is normally contaminated.
Before handling or moving contaminated materials or instruments, the following precautions should be taken:
„ Wear rubber or latex gloves of suitable thickness and a face mask;
„
wash your hands, with the gloves already on, using a germicidal detergent;
„ separate the instruments suitable for sterilization from those that are not;
„
do not carry contaminated instruments in your hands, but always use a tray suitable for carrying instruments;
„ be very careful of instruments with sharp parts that can puncture normal rubber gloves; in such cases, protect your hands
with gloves of sufficient strength;
„
once the handling and transfer of the contaminated materials is finished, carefully wash your hands while still wearing
the gloves.
5.4.2 Treatment of materials and instruments before sterilization
CAUTION
Failure to clean and remove organic residues from the instruments to be sterilized can affect the
sterilization process and cause damage to the instruments and/or the sterilizer.
Clean and process the materials and instruments to be sterilized as indicated in the following points:
1. Rinse the instruments thoroughly under running water immediately after using them.
2. Divide metal instruments into groups, according to the type of material of they are made (e.g.: brass, aluminium, stainless
steel, carbon steel, chrome-plated metal) in order to avoid electrolytic oxidation.
3. Perform a preliminary wash with an ultrasonic device that uses a mixture of water and germicidal solution (follow the
manufacturer's instructions) or use a washer-disinfector. For best results, use a special detergent for ultrasonic cleaning,
with a neutral pH.
CAUTION
Solutions that contain phenols or quaternary ammonium compounds can cause corrosion to the
instruments and the metal parts of the ultrasonic device.
4. After ultrasonic cleaning, rinse the instruments and visually check that all residues have been completely removed; if
necessary, repeat the ultrasound cleaning or wash the instruments thoroughly by hand.
CAUTION
To avoid mineral deposits on the instruments to be treated, use demineralized or distilled water for
rinsing. If normal hard tap water is used, the instruments should be thoroughly dried.
5. When cleaning handpieces, in addition to the steps described above, run a wash cycle using a device specially designed
for cleaning handpieces, which performs thorough internal cleansing together with lubrication.
6. For sterilization of porous materials, wash and dry the materials thoroughly before sterilization.
CAUTION
For washing fabrics and porous materials in general, do not use detergent with high concentrations of
chlorine and/or phosphates, such as bleach, as it can damage the support and the metal trays inside the
chamber during the subsequent sterilization cycle.
