Irish Cleanroom Society The Irish Cleanroom Society (ICS) is a not for profit membership subscription based organisation formed in 1998 to represent cleanroom professionals in Ireland The ICS is affiliated to the International Confederation of Contamination Control Societies (ICCCS) The primary focus is to promote best practice knowledge and skills, understanding and harmonisation of cleanroom and contamination control technology and standards among users and professionals in Life Sciences, Healthcare, Food, Microelectronics and Micromanufacturing
6
ICS Objectives Promote the development of cleanroom and contamination control technologies throughout Ireland Heighten the awareness of cleanroom and contamination control technology among all users inc industry, educational, institutional establishments, government bodies & the public Assist in the standardisation and harmonisation of cleanroom and contamination control Organise seminars, exhibitions and peer to peer forum workshops for the dissemination of knowledge & experience gained in cleanroom and contamination control technology Represent Ireland on the international stage
7
ICS & Education Education and Training are at the core of ICS activities The ICS has been a major contributor to the CTCB-I (Cleanroom Testing and Certification Board International) since its inauguration in 2002 and has provided nearly 20 Cleanroom Technology and Testing courses with over 200 candidates from Ireland and around the world Since 2005 the ICS has helped lead the ICEB initiative of the ICCCS to accredit, harmonise & licence cleanroom training courses across national cleanroom societies with the emphasis on certification through examination
8
ICS on the International Stage The ICS represents Ireland at international level on ISO TC 209 for cleanroom standarisation where Ireland is a voting member Conor Murray is Head of Delegation for Ireland & a subject matter expert on the TC & a number of WGs The ICS is an active member of the ICCCS, International Confederation of Contamination Control Societies ICS an active member of the International Cleanroom Education Board (ICEB) Ireland hosted the 21st biennial symposium in 2008
9
ICS Linkages in Ireland The National Standards Authority of Ireland are the Irish representative body in CEN and ISO Standards organisations Their Health Care Standards Consultative (HCSC) committee has established a subcommittee, SC 13 concerning cleanrooms The Irish Cleanroom Society play a leading part in this. Conor Murray is Convener of SC 13 and represents Ireland at ISO TC 209 concerning Cleanrooms and associated controlled environments The ICS works closely with FAS on cleanroom training and up skilling

ISO 14644 TD Proposal Deals with the role of an ISO 14644 Technical Document as an Overview, Introduction, Explanation and Context in dealing with updates and changes to ISO 14644 & ISO 14698 re airborne and surface cleanliness classification by total particles, viable, chemical and nano particles Approved in Milan 2011- to be presented to ISO TC 209 in Zurich, September 2012
19
ISO 14644 Issues Historical development and focus on Airborne Particles New standards deal with surfaces, chemicals and nanoparticles Need backward compatibility Where to put the history, context, perspective, objectives, usage & application notes
20
ISO 14644 Issues Existing definition of cleanroom relates to airborne particles ie total particle concentration in air New definition needs to address the concept of a controlled environment where the control could be total particles, viables or chemicals in air and/or on a surface

ISO DIS 14644 -1 & - 2
24
ISO DIS 14644 -1 & -2 Apply good science and statistics Remove confusion and inconsistencies Simplify terms Use more precision Use a Table for Classification instead of the universal formula
25
ISO DIS 14644 -1 Copenhagen DIS Vote May ‘11 – unanimous but > 200 comments Differences over no of samples for confidence level and maximum area to determine classification Differences over method of selection of sample locations, application of statistics – random selection Differences over treatment of 5 micron particles Differences over normative use of ISO 21501-4
26
ISO DIS 14644 -2 Copenhagen DIS Vote May ‘11 – unanimous Decided to remove classification and keep to Periodic Testing & Monitoring Agreed that Classification and Periodic Testing are NOT the same – amount of testing Differences over inclusion of Differential Pressure

29
ISO 14698 Issues ISO 14698 not in line with ISO 14644 No Tables of Classification Not up to date with Risk Assessment & Risk Management techniques (eg ICH Q9 QRM) No Check Lists of “Things to Consider” Not up to date with technology advances in Rapid Microbiological Methods (RMM) & Instantaneous Microbiological Detection (IMD) (eg ATP, Bioluminescence)
30
ISO 14698 Issues Cannot “Monitor a process into Control” Not enough clarity on differences, issues and guidance on Aseptic vs Non Sterile applications Not enough guidance on Airborne vs Surface biocontamination risks and control Overall seen as not easy to read & use

ISO Standard Principles ISO Standards are NOT industry specific Bird’s Eye view from 25,000 feet Normative (Must do) & Informative (Should do) Based on good science with clear and independent guidance Short & concise, easy to read & use Check Lists, flow charts, suggested methods, options on best practice methods, choices, examples.
33
ISO Working Group Principles Working Group is a team of international experts nominated by each member country Terms of reference set by TC 209 Duration varies but typically 2 - 5 years Act as Subject Matter Experts (SMEs) in their field
34
ISO Working Group Principles
Capture best science and international expertise “Get all the toys on the table” and play with them Everything on the table Open dialogue encouraged until the end Let “good science” prevail
35
ISO 14698 Challenges - Limitations of Quantitation Current measurement ‘technologies’ limited to orders of magnitude resolution, especially in low density populations Species recovered using these technologies limited due to incubation methodology (inc media, temperature, pH, aerobic/anerobic, etc.) “Environmental microbiologists recent research indicate that some species are inter-dependant & one species will not culture successfully without the presence of the other”
36
ISO 14698 Challenges - Diversity of People People are the greatest source of biocontamination Unpredictability and uncertainty of Human behaviour “80% of the species found in the human upper respiratory tract cannot be recovered”
37
ISO 14698 Challenges - Issues in clean spaces Below limit of resolution for current technologies i.e. 1 cfu recovered may be indicative of 1cfu or perhaps >10cfu, impossible to accurately and repeatably determine Risk of false positives high due to likelihood of accidental contamination during collection and incubation
38
ISO 14698 Challenges - Process/ Application Specific In some cases, all species are considered harmful In some cases there is ‘background counts’ of cfu of species considered ‘normal and nonharmful’ In some cases, some species are considered ‘objectionable’ and are not tolerated at all
39
Aseptic Processing - 5μm Particles & EU GMPs “In Grade A and B zones, the monitoring of the ≥5.0 μm particle concentration count takes on a particular significance as it is an important diagnostic tool for early detection of failure.” “... consecutive or regular counting of low levels (of ≥5.0 μm) is an indicator of a possible contamination event and should be investigated.” Particles ≥5.0 μm could be skin particles carrying biocontamination
