What daily and weekly checks are carried out by on-site personnel for Vacuum capable steriliser?
- Check the door seal for damage or contamination and clean
- Verify the condition of the load carrier and chamber
- Fill and drain water reservoirs on a daily basis
- Run air leakage test
- Run Bowie-Dick test cycle

Why do we carry out testing on decontamination equipment?
Verify functionality
-> ensure components are working
-> ensure readings of temperature, time and pressure are accurate
-> helps identify deviation from required set points
What information may manufacturers provide about maintenance of components?
Costings for spare parts/consumables
Frequency of replacement of parts and consumables
What must we verify for each decontamination machine?
- The temperature is reading correctly
- The pressure is reading correctly
- The chemicals are being dosed in the required volume
- The stage timer is accurate and correct
- The machine is heating correctly
- That all necessary valves/components are operational
Who validates cycles?
Competent/test person
-> must be able to prove they are qualified to carry out work with certification
What is the difference between indicated and recorded temperature?
Indicated- from machine temperature probe
Recorded- built in independent temperature probe
Measured- produced by putting probes in machine and recording cycle as it happens
What are all the tests that are carried out by competent person for AWD?
Safety checks
Water quality checks
Calibration of test instruments
ACT
Verification of calibration
Cleaning efficiency test
Thermometric test for thermal disinfection
Tracking test
What are all the tests that are carried out by competent person for steriliser?
Weekly safety checks
Calibration of test instruments
Air leakage test
ACT- verification of calibration
Small load thermometric test
Calibration checks
Air detector function tests
BD test
What do cycle grafts help us check?
All cycle set points are being achieved
What certificates should be included in report on equipment by competent person?
Calibration certificates for the equipment
Certification from the Competent Person
What does testing our equipment assure us of?
Our equipment used to process instruments is meeting all necessary standards meaning our instruments are cleaned, disinfected and free of viable micro-organisms
What is the obligation of the dentist when buying decontamination equipment?
You must verify that any of the equipment you intend on using, has gone through this rigorous process so that you have verification that no danger to patients will arise from your use of any of these products
You are buying from a reputable company that can prove that their manufacturing is in line with standards
-> materials are required grade
-> manufacturing environment is not contaminated
