Decon BDS5 Flashcards
What are the stages of the decontamination cycle?
- Acquisition - practices should have a documented policy for the purchase of any medical devices
- Cleaning - Automated cleaning is preferred to manual cleaning
- Disinfection - Reduce number of viable microorganisms
- Inspection - All instruments carefully examined for organic material and/or damage under magnification
- Packaging - Where products are to be packaged, the materials should be. Compliant with the relevant European Standards (BS EN 868)
- Sterilisation - The following should be taken into account; process used, type of cycle and relevant cycle parameters
- Transport
- Storage - Areas designated for storage should be clean, dry, well ventilated and secure. Stock rotation should be used FIFO.
- Use
- Transportation (dirty)
- Disposal
The location for decontamination processes may be divided into what three areas?
Dirty - cleaning of used devices
Clean - inspection, assembly and packaging
Clean - sterilisation and post sterilisation storage
What are the three main sources of contamination of a product prior to its sterilisation?
Facilities
Personnel
Raw materials/components
Who has the overall responsibility of the decontamination process?
Dental Practitioner/Owner (maybe referred to as the decontamination manager)
Practitioner must have undertaken periodic training to update their knowledge, skills and competence
What are policies?
When should policies be available for the decon process?
What are procedures?
How are procedures relevant to the decon process?
Policies describe the aim of a particular process
Should be available for all parts of the decon cycle including acquisition and disposal
Procedures describe how to achieve compliance with a policy
They should define, document and control all stages of the decon process

What are the key elements of the cleaning cycle?
Time
Temperature;
The temp of the initial wash is usually below 40 degrees to avoid coagulation and fixing of body tissues to instruments
Chemicals; Acidic detergents Neutral pH detergents Alkaline detergents pH 10 High alkaline detergents >pH10 Enzymatic detergents
Energy;
This is usually delivered in the form of physical energy in the water jets from the rotating spray arms.
What is the preferred back up cleaning method if an AWD is unavailable?
What is its documented procedure?
Ultrasonic cleaner
Correct loading procedure Correct choice of operating cycle time Operating temp Correct choice of detergent Draining of ultrasonic bath at 4 hourly intervals or sooner if grossly contaminated Record details of items processed
What does a typical washer disinfector cycle compromise of?
- Flush - remove gross contamination at <35 degrees
- Wash
- Rinse - remove residual detergent
- Disinfection
