Recorded Webinars: Meeting Architecture Constraints in SIF Design
Minimum architecture requirements were defined in IEC 61508 in 2000. For the process industries, these requirements were “simplified” for IEC 61511 and a new optional table was added for “Prior Use” elements. The 2010 edition of IEC 61508 has retained the existing requirements, now called Route 1H, and added a new alternative set of requirements for elements with “90% confidence” in failure data and failure modes. This web seminar will review the alternative architecture constraint requirements including the new Route 2H and show one method that exida is using to claim 90% confidence in the failure rate and failure mode data.

Final Elements and the IEC 61508 Certification
Attendees of the webinar will:
• Learn how IEC 61511 impacts turbine safety systems
• Develop an understanding of how implementing IEC 61511 can be used to show compliance with safety regulations
• Examine strategies to effectively implement the requirements of the standard
Recorded Webinars: Improving Reliability and Safety Performance of Solenoid Valves by Stroke Testing
Solenoid valves integrated into the design of emergency shutdown valves (ESD) used in industrial process systems, can tend to bind, i.e., to become stuck in one position, when not moved for long periods of time. This binding, also known as failure due to excessive stiction, has significant negative impacts on the valve’s reliability and safety performance. It is a serious and costly problem normally addressed by expensive and time-consuming proof tests which typically have required a process shutdown to perform testing. This webinar will describe an effective, alternative in-service testing protocol, known as valve stroke testing, which verifies whether or not the solenoid valve is stuck in position. Best practice procedure for implementing the valve stroke test will also be described, and a quantitative example of how valve stroke testing significantly improves safety performance will be provided.
Recorded Webinars: Applying IEC 61511 to Industrial Turbines: A Case Study
Turbines and their associated equipment have long been a focus of safety and safety protection functions driven by the risks to personnel and damage to equipment. Now the international safety standards are being applied in addition to local standards and requirements. Meeting IEC 61511 requires a new perspective on turbine safety systems and presents both challenges and opportunities for turbine owners. This webinar provides a review of the IEC 61511 standard and highlights its impact on turbine safety systems.
Attendees of the webinar will:
• Learn how IEC 61511 impacts turbine safety systems
• Develop an understanding of how implementing IEC 61511 can be used to show compliance with safety regulations
• Examine strategies to effectively implement the requirements of the standard
Recorded Webinars: Functional Safety: An IEC 61508 SIL 3 Compliant Development Process
This webinar provides developers of safety application products with an overview of how to implement a development process that meets the requirements of Safety Integrity Level (SIL) 3 of the IEC 61508 standard. It will illuminate and interpret the requirements of the standard, including the 2010 version, so that organizations can adapt their existing processes to comply with the standard. Material will be taken from the book of the same name, as presented by the author.

Recorded Webinars: The 7 Things Every Plant Manager Should Know About Control System Security
Not that long ago, the move towards “open systems” and the resulting incorporation of off-the-shelf technologies represented a huge step forward in control system design. System integration became easier, product development by manufacturers was accelerated, and training leveraged common tools and concepts. While the benefits have been tremendous, open technology has made control systems open to security vulnerabilities, putting production and human safety at risk. Nothing has made that risk more evident than the Stuxnet virus which has made headlines since it was discovered in July 2010. Countering these threats requires organizations to develop a better understanding of their process control system security risks and how to address them. In this webinar, we will discuss the seven things that every plant manager and automation professional should know about industrial control system security. We will also discuss how to apply best practices from standards such as ISA 99.02.01 to mitigate these risks.
Recorded Webinars: Benchmarking Industry Practices for the Use of Alarms as Safeguards and Layers of Protection
This webinar discusses current industry practices around the use of alarms as safeguards and layers of protection as established by a recent benchmark survey of over 200 safety practitioners from around the world. Areas explored in the survey and will be discussed include:
Typical and maximum claimed risk reduction
Considerations used to determine whether an alarm can be credited with risk reduction
How often IPL alarms are determined to be invalid or ineffective in operation
Practices for display and annunciation through a Human Machine Interface (HMI)
Key results and conclusions will also be presented as well as recommendations on where industry should focus on improvement.

Recorded Webinars: How to Create an Alarm Philosophy Document
Creation of an alarm philosophy document is the cornerstone for development and sustainability of an effective alarm management program and the first stage in the ISA-18.2 alarm management lifecycle. The alarm philosophy document establishes the guidelines for how to address all aspects of alarm management at a site - including roles & responsibilities, rationalization, design, operations, maintenance, testing, training, and management of change. This webinar will discuss one successful methodology for creating a philosophy that minimizes the time and resource commitment of plant personnel. It will also review some of the key content that should be included and the typical decisions that must be made when creating the document.
