Mitigating Catastrophic Risk: Key Elements of an Effective Functional Safety System in Olefins Plants

3 December 2025

Functional safety in an olefins plant is essential to ensure the safe operation of highly risky processes and minimize the likelihood of catastrophic accidents. This process operates under extreme conditions and high temperatures and employs complex processes to convert raw and intermediate materials into products. Potential consequences such as fire and explosion, inadvertent chemical spills, and electrical threats exemplify some risks associated. This webinar analyzes the key aspects that make up an effective functional safety system, in accordance with standards such as IEC 61508 and IEC 61511. The most relevant elements include the identification of safety instrumented functions (SIFs), the determination of the safety integrity level (SIL), and the design and implementation of safety instrumented systems (SIS). The integration of these elements not only reduces operational risks but also improves reliability, availability, and regulatory compliance at critical facilities.
