Synopsis

There is no shortage of material that expounds the theory of functional safety, but precious little about the practice i.e. actual implementation in 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. This expanded third edition updates previous material and has several new chapters:• Security: Physical & Cyber• SIL & Cybersecurity Levels (SL)• Common Mode & Beta Factors• Proof Test Coverage Nomination• Multiple SIF Layers• Human Error• Overrides & Resets• Consequence Mitigation in LOPA• SIL4 Other 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• Evaluation of Compound (Multi) SIF• Leading Indicators & FSA4• Mitigation Systems• Modification, Decommissioning & FSA5• Functional Safety Management Planning• Suspended Load Process Safety Model• Aggregate Risk and Risk Profiles
