Three-Day Course Overview
This three-day training provides a comprehensive overview of the IEC 61511:2016 and ANSI/ISA 61511:2018 standards for the process industry. The complete safety life cycle of IEC 61511 will be discussed by industry experts, and practical examples and exercises will be provided.
