Download or read book Functional Safety in Practice written by Harvey Dearden and published by Createspace Independent Publishing Platform. This book was released on 2016-01-07 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
