Safety Instrumented Function (SIF) design is based on performance requirements. During the design of the SIF, engineers make various assumptions, including assumptions concerning SIF equipment failure rates, SIF demand rates, proof test frequencies, and mission time which form the basis for the expected operational SIF performance. Are those assumptions realistic?…
La seguridad funcional en una planta petroquímica es esencial para garantizar la operación segura de los procesos y minimizar accidentes catastróficos. Las instalaciones petroquímicas, como las plantas de olefinas, son emplazamientos industriales que transforman petróleo y gas natural en una amplia gama de productos como plásticos, detergentes, adhesivos, caucho y alimentos. Este proceso opera en condiciones extremas, donde se emplean procesos complejos para convertir materias primas en productos. Algunos de los riesgos asociados son incendios y explosiones, derrames químicos accidentales, corrosión y amenazas eléctricas. Este estudio analiza los aspectos clave que conforman un sistema de seguridad funcional eficaz en particular en hornos de craqueo térmico, de acuerdo con normas como IEC 61508 e IEC 61511. Los elementos más relevantes incluyen la identificación de las funciones instrumentadas de seguridad (SIF), la determinación del nivel de integridad de seguridad (SIL) y el diseño e implementación de sistemas instrumentados de seguridad (SIS). Además, se abordan la gestión del ciclo de vida de la seguridad, el análisis de riesgos, la validación funcional y los procedimientos periódicos de mantenimiento y pruebas.
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.
DUBAI, UAE – As industrial facilities across the Middle East accelerate their digital transformation, the gap between theoretical safety design and real-world operational performance has become a critical focus for asset integrity managers. To address this challenge, exida , a global leader in functional safety, alarm management, and cybersecurity, has…

The increasing connectivity of medical devices introduces new challenges for manufacturers and operators: cybersecurity issues can compromise not only data privacy but also patient safety. This webinar demonstrates how structured threat modeling can help teams systematically identify, understand, and mitigate cybersecurity risks throughout the medical device lifecycle.
We will walk through the steps of a threat-modeling workflow to illustrate how threats can be identified early, refined as the system architecture evolves, and linked to risk-reduction measures. The session highlights how threat modeling aligns with common risk-management practices in functional safety and cybersecurity, and how it can be integrated into a Secure Development Lifecycle (SDLC).
Participants will learn how focused threat analysis supports compliance with key regulatory requirements and strengthens the overall security posture of connected medical devices.

This exSILentia Feature Spotlight highlights the key updates in version 4.15.1, focusing on expanded flexibility, language support, and enhanced cybersecurity modules. The most significant new feature is the introduction of User-Defined Checklists, allowing users to create custom templates for any module within the safety or cybersecurity lifecycle (e.g., PHA, LOPA) and link them across different project tasks. Additionally, the application now supports French and Spanish languages.
For cybersecurity, the risk assessment function has been separated into two distinct modules: the High-Level Risk Assessment (HLRA) and the Detailed Level Risk Assessment (DLRA) (previously a single Cyber PHA module), providing a clearer workflow and the ability to differentiate between hackable and non-hackable countermeasures, thereby improving the rigor and structure of the cyber safety analysis.
Effective loss prevention requires identifying risks in both process safety and cybersecurity. OT cybersecurity risk assessments follow standards/guidance like IEC 62443-3-2, and UK HSE’s OG-0086 with Process Safety handled by mostly by IEC 61511. For organizations adhering to IEC 61511, it is a requirement under Clause 8.2.4 to perform a security risk assessment, while in parallel, OG-0086 requires evaluating cyber resilience in Major Accident Hazard scenarios and Loss of Essential Services. Methodologies vary, but all must address worst-case consequences, threat likelihood, and control effectiveness. A sound assessment ensures regulatory compliance, aligns with best practices, and supports informed risk management decisions.
