Functional safety is the task of developing and implementing automatic safety systems used to manage risks in many industries where hazardous processes and machinery are used. Functional Safety from Scratch: A Practical Guide to Process Industry Applications provides a practical guide to functional safety, as applied in the chemical process industry, including the oil and gas, petrochemical, pharmaceutical and energy sectors. Written by a seasoned professional with many years of functional safety experience, this book explains the purpose of the relevant international standard IEC 61511 and how to achieve compliance efficiently. It provides in-depth coverage of the entire lifecycle of a functional safety system, assuming no prior knowledge of functional safety and only a basic understanding of process safety concepts. SIL assessment, the functional safety management plan, the safety requirements specification, verification, validation and functional safety assessment are covered in particular detail.

Functional Safety from Scratch: A Practical Guide to Process Industry Applications is a highly practical source for process and instrumentation engineers, engineering managers and consultants, whether new to the field or already experienced.

• Focuses on the 'how to' aspects of functional safety
• Provides detailed explanation and guidance on how to develop the safety requirements specification
• Includes extensive coverage of safety lifecycle verification, SIS validation, and functional safety assessment
• Provides numerous practical exercises to confirm understanding and promote further thought
• Includes tips for those preparing for functional safety examinations
• Oriented towards an international audience, especially those for whom English is not their first language

Dr. Peter Clarke is a graduate of the University of Oxford and Durham University in the UK. Originally from a chemistry background, he worked in biotech R&D for 5 years before spending 3 years in the UK fine chemicals and pharmaceutical industry in process and safety management roles. He subsequently moved into safety consultancy, where he has extensive experience in process risk management in oil & gas, petrochemical, semiconductors and energy. He has facilitated a considerable number of HAZOP, SIL assessment, LOPA and alarm management studies, in addition to Safety Case, Fault Tree, ALARP and HAZID.
