LOAD PREPARATION
Effective disinfection starts in the instrument preparation phase. To make sure this occurs, eliminate any possible
coarse residue remaining from previous activities using suitable soaking methods and treatments before placing the
instruments in the appropriate baskets “delicately.”
Instruments made in stainless steel cannot be immersed in physiological solutions of sodium chloride for any reason,
as extended contact with this solution provokes corrosion creating holes and damage to the surface due to stress
corrosion.
Avoid overloading the instrument basket holders
. Slag, skin disinfectant residue, physiological solutions, etc. must
not enter the treatment containers. The containers must always remain closed to avoid additional drying. It is
advisable to perform dry treatments when possible.
The instruments are immersed in a combined solution of disinfectant and detergent with no fixed protein effects, as a
preference when treating liquids. However, disinfectants based on aldehydes have a fixing effect. Therefore, we
strongly suggest precisely following the indications provided by the manufacturer regarding concentrations and action
times, as well as the possible addition of detergent additives.
Always avoid long time intervals between this preliminary treatment and the instrument washer treatment
as the
risk of corrosion exists for both methods.
The instruments must be placed appropriately in instrument holders suitable for machine washing. To assure effective
cleaning,
the articulated instruments (scissors, clamps and forceps) must be opened to avoid overlapping their
surfaces as much as possible
. The instrument holders, such as baskets, racks and fixing devices, must be designed to
prevent shadow areas
in the following cleaning and disinfecting phase.
Instruments that can be disassembled must be put away according to the instructions provided by the manufacturer.
Instruments used for micro-surgery must be placed on special racks or appropriate fixing devices.
Residue present on orthodontic instruments, such as material used for lead sealing or acid substances used for
removing cement, must be eliminated immediately after use to prevent the risk of hardening and/or corrosion.
Components of motor operated surgery systems must be disassembled immediately after use according to the
instructions provided by the manufacturer.
Simple tools, such as drills or saw blades can be treated like surgical instruments only if they are reusable medical-
clinical products.
Avoid direct and repeated contact with dirty instruments as much as possible.
Always use extreme caution. Use all the individual protective devices available for this type of operation,
before and after treatment.
