FOREWORD TO THE BOOK

A book of this type is long overdue and finally fills a void that has been present in this industry for many decades. It deals with the design and safe installation of different gas systems and is written in plain English suitable for both the novice or expert. Importantly it is written in texbook style where each chapter is complete by itself in dealing with each specific gas and thereby not necessitating that each reader read the entire document.

In my personal experience, if a book like this had existed three decades ago, my own work would have been much improved. I was setting up a Gene Targeting and Stem Cell Laboratory at the John Curtin School of Medical Research at the Australian National University. This involves the genetic manipulation of mouse embryonic stem cells and their microinjection into mouse pre-implantation embryos, all done under CO2 buffered tissue culture. Our initial results were very poor even though we were using state-of-the-art equipment and reagents. By chance, Jim Moody visited my laboratory and immediately pointed out a major flaw in our laboratory design: we had used copper to pipe the CO2 gas. Jim directed me to an article in Nature by Brinster in 1972 that clearly shows the toxic effect of copper ions on pre-implantation embryos. We immediately re-piped our CO2 in stainless steel, and overnight our success dramatically improved to become one of the most successful gene targeting laboratories both in Australia and internationally.

It is this type of personal knowledge that this book describes that has been gathered over a lifetime career. I cannot recommend this book more highly for those of us that always want the get things perfectly correct.

This new volume, Design and Construction of Laboratory Gas Pipelines: A Practical Reference for Engineers and Professionals, focuses on design and installation of laboratory gas pipelines. It instructs design engineers, laboratory managers, and installation technicians on how to source the information and specifications they require for the design and installation of laboratory gas systems suitable for their intended use.

The current use of specifications predominantly taken from medical gas standards for this type of work is not always suitable; these standards are for use with medical grade gases that have a purity level of 99.5%. The purity levels required in laboratories, however, start at 99.9% for general industrial use through to 99.9995% (Ultra High Purity (UHP)) and higher. Regular medical gas standards are also unsuitable for use with the oxidizing, flammable, and, in some instances, toxic gases that are regularly encountered in laboratories. As need for gas purity increases, the methodology used to design a piping system must vary to meet those parameters, and this reference provides the necessary information and resources.

There are no comprehensive single sources of technical references currently available in this market, states the author, and the generally supplied specifications provided to the construction industry are usually generic and not specifically targeted for the gases in use. The results provide extremely poor quality designs and, in some instances, unusable systems. With over 40 years of specialization in the industry from project management to systems design, testing, and commissioning of projects with values in excess of $15 million, the author comprehensively fills that gap with this rich resource.

Key features:

Provides information on types of laboratories that use laboratory gases and the equipment used for the various piped gases
• Examines the equipment used to supply gases for laboratory use and also looks at the designs for plants used for in-house air and vacuum systems
• Provides details on the various methods of construction and the materials used to ensure the purity of the gases remain as supplied from the manufacturers
• Incorporates the design methodology used to meet the various requirements of the laboratory and the information required to ensure the correct engineering is provided
• Presents information on the purity levels of the inert gases and the data on the equipment used for pipelines and compatibility issues
• Provides information on the purity levels of the flammable and toxic gases and the data on the equipment used for pipelines and compatibility issues for the gases used in laboratories
• Presents an example of a simple laboratory gas specification that provides guidelines on the information necessary to provide a set of design documents

About the Authors / Editors:
James Moody
Consulting Engineer Specializing in Medical and Laboratory Gas Systems, Australia

James (Jim) Moody has in excess of 40 years of experience working continuously in the field of piped gases, particularly in the health care industry and at industrial, scientific, and university laboratories. James’s experience includes working as a Project Manager and Design Engineer on multimillion-dollar projects and was Managing Director of one of the largest medical and laboratory gas installation companies in Australia. James is currently working as a consulting engineer specializing in medical and laboratory gas systems. Over the years James has been involved in the design and development of products and equipment associated with the controls and alarms for gas reticulation systems, winning the Australian Design Award for his tourniquet control panel used in operating theaters. Another design breakthrough has been in plume (smoke) evacuation systems for the removal of the plume generated by medical devices such as YAG Lasers and devices for processes in electrocautery and diathermy. James has been a member of Standards Australia (HE-017 Medical Gas Systems) and a member of Australia’s delegation member of the International Organization for Standardization (ISO) since the 1990s. The HE-017 Medical Gas Systems Committee manages a wide variety of standards publications, including AS 2896-2011 relating to medical gas pipeline systems. In 2015 James was elected as the chair of the committee. He has approximately six years writing the standard ISO 16571 Systems for Evacuation of Plume generated by medical devices. James has also written several papers on piped medical and laboratory gases. He was a part-time lecturer at Sydney University, Australia, as well as for various consulting engineering associations, hydraulics engineers associations, and the Chartered Institute of Building Services Engineers.
