There is no shortage of material that expounds the theory of functional safety, but precious little about the practice i.e. actual implementation in what is sometimes called the 'real world', where we routinely meet a variety of constraints that do not allow the theoretical model to be fully realised. This book is intended to bridge that gap. Readers are provided with the considerations that should inform their choices and judgements. The focus is on the process industries, but most of the material will have a direct 'read across' to other sectors. Questions considered include: * Functional safety misrepresentations and misunderstandings * Disconnects between theory & practice * SIL determination issues and ALARP considerations * How and when to use engineering judgement * How to manage competence * How to address systematic capability * How to handle legacy plant * Trip setting nomination & process safety time * Certification v 'Prior-Use' * How to validate failure rates during operation * How to manage useful life expiry * How to manage proof testing * What to expect from the regulator

This ebook explains what SIL and functional safety means in a nutshell. The book is intended for everybody who is new to functional safety and SIL and wants to have a full overview without being lost in the details. It is excellent for managers that need to understand quickly what functional safety is all about and how it will influence the work of their employees and their products and/or services. It is excellent for engineers and professionals that want to get started with functional safety and understand the big picture before going into detail. Many standards, guidelines and other publications exist that talk about functional safety. All of them with their own level of detail. This book does not to go into the details of what has to be done according to what standard and what not. It explains main functional safety concepts so that you know everything you need to know to get started. Functional safety is not rocket science and once you understand it and applied it a few times in practice you will notice it is just good engineering practice. This book tries to explain that good engineering practice. Functional safety standards can be confusing and contradicting at times and sometimes they require things that make no sense. You do not need to understand the standards in order to apply and be good at functional safety. If you understand the concepts explained in this book you can apply functional safety into your organisation and to your products, with or without following the exact requirements of standards. Actually once you understand how functional safety works you most likely will go beyond what standards say and create your own functional safety organisation of excellence. And if you do that, well then you are well on your way in becoming a longtime winner as suppose to a short term fuse.

Laboratory Safety: Theory and Practice focuses on theoretical aspects of the hazards the students, technicians, and scientists encounter in the laboratory. It presents methods of risk assessment that can be applied to technologies as they are translated from the scientist's mind to the laboratory bench. It is organized into three sections designated as General Laboratory Safety, Biological Laboratory Safety, and Medical and Psychological Factors. The first section, encompassing three chapters, discusses hazards found in almost all laboratories; pertinent safety theories and practices; ubiquitous compounds that are either toxic or carcinogenic and guidelines for their use; and radiation hazards. Chapters 4 to 7 focus on the safety in the biological laboratory. Discussions on relatively complex group of viruses, approach to recombinant DNA research, and awareness on the possible hazards associated with the field are included in this book. Chapters 6 and 7 present design and function of biohazard laboratories and the hazards relating to laboratory animals. The final section discusses medical surveillance of persons at risk and the psychological factors involved in accident control. It presents a comprehensive list of chemical agents, their sources, subsequent physical effects, and the accepted mode of medical surveillance. Various genetic screening tests and their potential use for the evaluation of presumptive and actual mutagens are also covered. This book is ideal for safety and design engineers, students, technicians, and scientists.
