27
What is SOP in an LDU?
Standard Operating Procedures Allow us to make our activities reproducible and consistent. Easy for other members of staff to follow. Used for example for the daily checks.
28
First step of decontamination process after transporting instruments and PPE/hand hygiene)

29
Directions for proper loading of the washer disinfector
No overlapping, hinges open, disassemble assemblies, do not overload
30
What is done following washer disinfector in the LDU?
Inspection of processed instrumentation We use an illuminated magnifier to identify any biological matter that might still be present If there is any contamination on the surface of the instrument at all they must be further processed
31
Most important parts of instrumentation to inspect following washer-disinfector
Hinges, joints, textured or threaded surfaces
32
What is done if biological matter is still present on instruments after washer-disinfector?
Manual cleaning and ultrasonic bath

35
What is the recommended brush for manual cleaning?
Long handled, soft bristled, non metallic brush
36
What is done after manual cleaning and ultrasonic bath?
Instruments must go back through the washer-disinfector (the reason for this is the high temperatures and contact achieved during the disinfection part of the automated cycle).
37
What do we reinforce the washer disinfector process with if necessary? Why is this?
Manual cleaning and ultrasonic processes as it is essential that all biological matter/proteins/bodily fluids are removed entirely
38
What % of contamination is removed once the washer disinfector stage is completed?
95%
39
What temperatures are reached in the washer-disinfector, and for how long?
90-95 degrees celsius, for a minimum stage hold time of one minute, allowing the minimum contact rate of 12 seconds
40
Why is it necessary to sterilise after washer disinfector?
There are still pathogens that can survive the 90-95 degrees held for a minimum of 1 minute in the WD, and we need to sterilise all of our instrumentation through a piece of equipment that has the capability to achieve all of the recognised standards and set points, internationally agreed, to constitute sufficient sterilisation

46
If the sterilisation temperature of a cycle achieves 135.2 degrees celsius what is the corresponding pressure range and minimum hold time?
3.05-3.35 bar 3 minutes
47
If instruments need to be sterile at the point of use, how should they be prepared for processing and what equipment must be used?
They should be wrapped in paper packaging before processing in vacuum capable type B steriliser
