Book Description

A self-contained and practical book providing step-by-step guidance to the design and construction of cleanrooms, appropriate testing methodologies, and operation for the minimization of contamination… This second edition has been comprehensively revised and includes extensive updates to the two chapters that contain information on cleanroom standards and guidelines. The chapter on risk management has been extensively revised, especially the section on risk assessment. Other new subjects that have been added to the various chapters are those on clean-build, determination of air supply volumes for non-unidirectional airflow cleanrooms, RABS (Restricted Access Barrier Systems), contamination recovery test methods, entry of large items into a cleanroom, glove allergy problems, and how to develop a cleanroom cleaning programme. Used for in-house training and a textbook in colleges, this volume is for cleanroom personnel at all levels. It provides novices with an introduction to the state-of-the-art technology and professionals with an accessible reference to the current practices. It is particularly useful in the semiconductor, pharmaceutical, biotechnology and life sciences industries. William Whyte is an international authority in cleanrooms, with over 45 years experience in research, teaching and consulting in the electronic, healthcare and pharmaceutical industries. He is a member of British and International standards committees writing the International Cleanroom standards, and has received numerous awards for his work in Cleanroom Technology. A comment on the first edition: "...extremely useful and helpful...very well-written, highly organized, easy to understand and follow..." (Environmental Geology, 2003)

Regulatory agencies worldwide have issued directives or such requirements for air quality standards in embryology laboratories. This practical guide reviews the application of clean room technology or controlled environments specifically suited for Assisted Reproductive Technology (ART) Units. Its comprehensive coverage includes material on airborne particles and volatile organic compounds, including basic concepts, regulation, construction, materials, certification, clinical results in humans, and more.




Introduction to Contamination Control and Cleanroom Technology


Book Description

Contamination control is being used by more and more industries where the highest level of cleanliness and hygiene is of vital importance. This book covers the basic principles of contamination control and cleanroom technology from a holistic point of view. It deals with cleanliness and hygiene and their effects on the outcome of a process, reflecting the latest results from both scientific and practical points of view. The following topics are covered: contaminants and how they are measured cleanrooms and clean zones cleaning and decontamination cleanroom clothing the impact of people on cleanliness. Intended as an introduction to the area of contamination control, the text is also an excellent source of knowledge for people with both theoretical and practical experience. The Swedish version has been used for a long time within the Nordic countries as a basic training textbook within the pharmaceutical, microelectronics, food and beverage, optics and many other industries.

Cleanroom Software Engineering


Book Description

Cleanroom software engineering is a process for developing and certifying high-reliability software. Combining theory-based engineering technologies in project management, incremental development, software specification and design, correctness verification, and statistical quality certification, the Cleanroom process answers today's call for more reliable software and provides methods for more cost-effective software development. Cleanroom originated with Harlan D. Mills, an IBM Fellow and a visionary in software engineering. Written by colleagues of Mills and some of the most experienced developers and practitioners of Cleanroom, Cleanroom Software Engineering provides a roadmap for software management, development, and testing as disciplined engineering practices. This book serves both as an introduction for those new to Cleanroom and as a reference guide for the growing practitioner community. Readers will discover a proven way to raise both quality and productivity in their software-intensive products, while reducing costs. Highlights Explains basic Cleanroom theory Introduces the sequence-based specification method Elaborates the full management, development, and certification process in a Cleanroom Reference Model (CRM) Shows how the Cleanroom process dovetails with the SEI's Capability Maturity Model for Software (CMM) Includes a large case study to illustrate how Cleanroom methods scale up to large projects.




Fundamentals of Air Cleaning Technology and Its Application in Cleanrooms


Book Description

Fundamentals of Air Cleaning Technology and Its Application in Cleanrooms sets up the theoretical framework for cleanrooms. New ideas and methods are presented, which include the characteristic index of cleanrooms, uniform and non-uniform distribution characteristics, the minimum sampling volume, a new concept of outdoor air conditioning and the fundamentals of leakage-preventing layers. Written by an author who can look back on major scientific achievements and 50 years of experience in this field, this book offers a concise and accessible introduction to the fundamentals of air cleaning technology and its application. The work is intended for researchers, college teachers, graduates, designers, technicians and corporate R&D personnel in the field of HVAC and air cleaning technology. Zhonglin Xu is a senior research fellow at China Academy of Building Research.

Clean Room Design


Book Description

This practical book provides detailed guidance on all aspects of clean room airflow, the mechanics of airflow, and how microbial contamination is carried. Ljungqvist and Reinmüller draw on years of experience in clean room design and operation. The book contains maps of the effect of human interference on unidirectional airflow and the potential for contamination. Particle challenge test methods and tracer gas detection methods are explained, and the impact and interpretation of the results obtained from these test methods are discussed. Topics include: o Dispersion of Airborne Contaminants o Contamination Risks o Wakes (including factual situations) o Open, Unidirectional Air Flow Benches (laminar flow benches) o Microbiological Assessment o Weighing Stations o Air Flow Through Openings o Mathematical Treatment of Contamination Risks o Simulation of Air Flows & Dispersion of Contaminants through Doorways in a Suite of Clean Rooms o Regulatory Requirements




Technologies in Food Processing


Book Description

With the unprecedented increase in the world’s population, the need for different foodprocessing techniques becomes extremely important. And with the increase in awareness of and demand for food quality, processed products with improved quality and better taste that are safe are also important aspects that need to be addressed. In this volume, experts examine the use of different technologies for food processing. They look at technology with ways to preserve nutrients, eliminate anti-nutrients and toxins, add vitamins and minerals, reduce waste, and increase productivity. Topics include, among others: • applications of ohmic heating • cold plasma in food processing • the role of biotechnology in the production of fermented foods and beverages • the use of modification of food proteins using gamma irradiation • edible coatings to restrain migration of moisture, oxygen, and carbon dioxide • natural colorants, as opposed to synthetic coloring, which may have toxic effects • hurdle technology in the food industry • the unrecognized potential of agro-industrial waste




Microbiological Contamination Control in Pharmaceutical Clean Rooms


Book Description

Contamination control in pharmaceutical clean rooms has developed from a jumble of science and engineering, knowledge of what has worked well or badly in the past, dependent upon the technology available at the time the clean room was built and subsequent technological developments. Surrounding it all is a blanket of regulations. Taking a multidisc
