Predesinfection

It will be necessary to exclude from the choice, the products containing of phenols, active chlorines or chlorides: because of their capacity to be corroded. It will be necessary to exclude aldehydes to be able to them from reinforcement of Prions to the action vapor, their allergenic capacity and their capacity to be corroded.
The realization of decontamination :
-To treat separately the chrome instruments,
-Decontamination must be carried out as soon as the instrument finished being useful,
-The water hardness must lie between 4°TH and 8°TH. A earthy water inhibits the antimicrobic effectiveness and can involve layers of sediment on the material during the use of certain types of products,
-The content chlorine of the water of dilution must be lower than 20 mgr/liter to avoid any risk of corrosion of the surgical instrumentation,
-Content of water of biogenic salts: iron, copper, manganese, must be weakest possible, with the risk to see these elements fixing itself on the instrumentation and to confer to him, with the wire time, a patina of aspect bronzes or rust,
-Scrupulously To respect the concentration which one should in no case neither to increase, nor to decrease with the risk to compromise the effectiveness or to increase the adverse effects,
-Never not to mix the products between them, especially not to add of detergent,
-The temperature of the bath must be, except for the proteolytic enzymes, of approximately 20° C. If the odor of the product is diffused, the temperature of water is too high and the active ingredients volitilize with the detriment of the effectiveness.

The immersion of the instruments must be total so that decontamination is extended to all the surface of the instrument but also to avoid the effect crushes between the air and water, on the surface of the bath, which would result in a starter of corrosion.
To respect the time of steeping. A time of too short steeping would compromise the decontaminating action, a too prolonged time, with certain corrosive substances, would induce an irreversible deterioration of the instrumentation. In general, whatever the product selected, the time of immersion of the instruments will have to never exceed 30 minutes by scrupulously respecting the concentration recommended by the laboratory.
