This practical guide provides a comprehensive introduction to the principles and implementation of Functional Safety in accordance with the internationally recognized standards IEC 61508, IEC 61511, IEC 61513, and ISA 84.

It explains the key requirements of these standards and demonstrates how they are applied throughout the lifecycle of industrial facilities—from concept and design through operation, maintenance, modification, and decommissioning. It combines the requirements of the standards with practical engineering experience, making complex concepts easier to understand and implement.

The book has also been featured in an IEEE magazine article, highlighting its contribution to the field of functional safety and industrial engineering.

Designed for both engineers and managers, the book bridges the gap between theory and real-world industrial practice. It addresses the technical, organizational, and management aspects of functional safety and provides practical guidance for developing, implementing, and maintaining effective Safety Instrumented Systems (SIS).

The methodologies presented are applicable to a broad range of industries, including oil and gas, offshore and onshore production, refineries, LNG plants, petrochemicals, chemicals, fertilizers, power generation, nuclear facilities, cement, mining, pharmaceutical manufacturing, and other process industries.

The book is also widely used as a reference for Functional Safety training, helping both engineers, managers as well as students understand the practical application of international functional safety standards in modern industrial projects.
