Recorded Webinars: Field Failure Data Collection Methods
Operational data is collected for many processes in order to identify problems, improve production, and improve safety. To achieve the maximum benefits, it is important to understand what data should be collected. This web seminar describes important data items that should be recorded in process automation system operation. Data collection standards are described, as well as a data collection system. This web seminar is targeted toward maintenance engineers, control system designers, safety system designers, and process automation management.
News Item: What are safety engineering ethics? Article in Hydrocarbon Processing
The article What are safety engineering ethics? by exida’s principal partner Dr. William Goble was featured in the March edition of Hydrocarbon Processing. In many professional engineer (PE) programs, continuing education is required. In some US states, this education includes specific requirements for engineering ethics training. The author recently attended…

Recorded Webinars: Introduction to LOPA: Layer of Protection Analysis
This webinar covers an overview of the key facets of performing layer of protection analysis (LOPA). It provides an understanding of the terminology, explains the transition from HAZOP to LOPA and lays the foundation for the basic probability math used by the methodology. Topics such as corporate risk criteria, human error, and common mode failure are addressed as they relate to LOPA.

Recorded Webinars: Practical and Robust Implementation of the IEC Functional Safety Standards
The release and adoption of IEC 61508 and IEC 61511 has created new requirements for all organizations involved with equipment used in safety related systems. As these functional safety standards are applied more broadly across industry and referenced more frequently as examples of best practice by industry and product standards the importance of meeting them is increasing. The requirements of the standards are new to many end users, EPCs, and manufacturers of valve, actuator, and other devices used in the final element which can result in effort invested in areas that do not guarantee compliance or increased safety reliability.
This webinar will:
· Review the functional safety standards along with the steps necessary to meet them
· Examine IEC 61508, including the Safety Lifecycle, key documentation necessary, and information that is supplied to end users
· Review IEC 61511 to examine the impact of the information supplied by manufacturers
· Provide examples from both the manufacturer and end user viewpoint to illustrate common pitfalls as well as best practices
Blog Entry: I Know My Requirements. Now What?
If you’ve written your new product requirements, you probably understand exactly what they mean. But will the other people on your project team? You also probably understand that some unwritten requirements must also be met. They’re just common sense and everyone knows what they are. What about that new software…
Recorded Webinars: Introduction to Process Hazard Analysis using HAZOP
This webinar covers the HAZOP methodology in the context of the overall process safety management lifecycle. It first provides a high level overview of the process hazards analysis (PHA) work process, detailing process safety management (PSM) expectations for the PHA. Process safety information is covered, explaining how it is needed in order to conduct the review and management of change (MOC) is shown in the overall PHA work process to illustrate the relationship between PHA and MOC. With the foundation set, details of the HAZOP methodology, including report documentation are presented.
News Item: exida Authors Web Feature for Valve Magazine
Loren Stewart, exida Safety Engineer authored a web feature for Valve Magazine titled “Understanding Functional Safety Standards.” While many people might recognize the term “functional safety” and assume they know what it means, for the purposes of standards, the term itself needs explanation. Finding an understanding and complying with functional…
Recorded Webinars: Ethics for Functional Safety Engineers: From Compliance to Culture
Join us for a look at ethics from the point of view of a functional safety professional. We will discuss the application of ethics to safety issues in the workplace. We will consider the role of ethics in moving from mere compliance to the rules to the development of an individual and corporate culture of safety which internalizes such values. Finally we will identify specific areas where safety professionals face choices and some mechanisms available for ethical resolution of these issues.
Blog Entry: Cycle Testing for Static Applications? NO!
The failure rates of certain mechanical components used in solenoid valves, actuators, and valves vary substantially depending on operation. Seals such as O-rings, for example have fundamentally different failure modes when used in applications with frequent movement (dynamic) versus applications with infrequent movement (static). Static is generally defined as “stationary…
Blog Entry: What is a “House Certificate?”
exida was recently auditing a systems level project per IEC 61511 . During such audits we check to verify that all equipment used in a safety instrumented function meets systematic capability by either IEC 61508 certification OR justification per reasonable IEC 61511 “prior use” criteria. Most engineers at Refinery A…
