12.2. ARRANGING THE LOAD
Always use personal protective equipment.
To get the best effectiveness of the sterilization process and preserve the material over time, increasing its useful life, follow the instructions below.
General notes for the positioning on trays:
• Arrange instruments made of different metals (stainless steel, hardened
steel, aluminium, etc.) on different trays or anyway on trays well
separated from one another.
• In case of instruments not made of stainless steel, put a sterilization
paper napkin or a muslin cloth between instrument and tray, avoiding
direct contact between the two different materials;
• In any case, arrange the objects sufficiently spaced from each other, so
that they can remain in such position for the whole sterilization cycle;
• Make sure that all instruments are sterilized in an open position;
• Position cutting instruments, (scissors, scalpels, etc.) so they can not
come into contact with each other during sterilization; if necessary, use
a cotton cloth or a gauze to isolate and protect them;
• Arrange recipients (glasses, cups, test tubes, etc.) resting on their side,
or upended, thus avoiding pooling water;
• Do not load trays beyond the limit indicated (see Appendix).
• Do not stack trays one on top of the other and do not put them in direct
contact with the walls of the sterilization chamber.
• Always use the supplied tray support.
• To insert and remove trays from the sterilization chamber, always use
the special supplied extractor.
Place one sterilization chemical indicator per tray to indicate when the process is complete: this will allow avoiding an unnecessary repetition of
the process on the same load or, worse, the use of unsterilised material. If packed material is sterilized, place the indicator inside one of the
packages.
Note for rubber and plastic hoses:
• Always rinse before use with pyrogen-free water; do not dry;
• Arrange hoses on tray so that their ends are not obstructed or squashed;
• Do not bend or twist hoses, but leave them as linearly stretched as
possible.
Notes for packages:
• Arrange packages next to each other, duly spaced and not stacked,
avoiding their contact with chamber walls;
• Should it be necessary to wrap special objects, always use a suitable
porous material (sterilization paper, muslin napkins, etc.), closing the
package with adhesive tape suitable for autoclave.
