Three Pillars of Process Safety: Catch exida’s Experts at Hazards 35 in Birmingham
October 13, 2025
exida, a global leader in functional safety, cybersecurity, and alarm management, is participating in the upcoming Hazards 35 Process Safety Conference, set for November 4–6, 2025, in Birmingham, UK. As a Silver Sponsor and exhibitor, exida is reinforcing its commitment to advancing process safety best practices by sharing critical knowledge through three distinct technical presentations.
A Focus on Integrated Risk Management
Hazards 35 is widely recognized as one of the world's leading process safety conferences, providing professionals with a chance to learn about the latest industry developments, best practices, updates on regulations, and practical solutions. exida's involvement underscores the company's belief in a holistic, integrated approach to managing major hazards.
Richard Butler, Senior Safety Engineer and Country Manager for Ireland & UK, emphaszied the value exida brings to the attendees:
"Hazards 35 is a key event for anyone serious about managing major hazards. exida's approach is unique because we seamlessly blend expertise in functional safety, cybersecurity, and alarm management to give clients a holistic view of risk. We don't just offer products; we bring the services and know-how needed to genuinely help customers manage their total process safety risk."
The conference themes include identifying and embedding good practice, the role of executive leadership, managing new technology implications, and cross-industry learning—all areas where exida’s integrated expertise provides practical, real-world guidance.

exida Technical Presentations
Attendees will have the opportunity to learn from exida's experts on topics critical to modern process safety:
Are Your SIS Performance Assumptions Realistic? Let's Find Out!
Iwan van Beurden, exida, USA
Safety Instrumented Function (SIF) design is based on performance requirements. During design, assumptions concerning SIF equipment failure rates, SIF demand rates, proof test frequencies, mission time are made. These form the basis for the expected performance.
Are those assumptions realistic? Is the SIF really operating as assumed?
IEC 61511 expects users to periodically compare actual performance with assumed performance. How do we do that? What is needed to get statistically viable results from the collected data? How does the data apply? How do we make sure we avoid drawing unrealistic conclusions?
This presentation will look at answers to these questions.
From Standards to Scenarios: Conducting Effective OT Cybersecurity Risk Assessments
Dwane Shelton, exida, Ireland
Effective loss prevention requires identifying risks in both process safety and cybersecurity. OT cybersecurity risk assessments follow standards like IEC 61511 and IEC 62443-3-2, and UK HSE’s OG-0086. IEC 61511 mandates security risk assessments for safety instrumented systems, while OG-0086 requires evaluating cyber resilience in Major Accident Hazard scenarios. Cyber risk assessments must define risk profiles for IACS zones and analyze cyber impacts on safety barriers. 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.
Process Alarm Management – A Suitable Vehicle towards the Improvement of a Site Safety Culture?
Richard Butler, exida, Irl & UK
While alarms are often used as a safeguard in HAZOP and LOPA studies, they are not always fully assessed for maturity which can be an indication of a poor site safety culture. This poster explores whether complementing process safety guidelines with Lean Management techniques can improve a site's safety culture. The CCPS IPL guidelines outline seven key requirements for alarm effectiveness, such as clear procedures, proper training, and routine testing. This poster studies how these guidelines and the ISA-18.2/IEC 62682 standards can be implemented using a Lean Management framework and whether this methodology can be a useful vehicle to initiate or re-invigorate the improvement of a site safety culture.
