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…

Blog Entry: The Problem with the Expert
I recall the first time I was called an “expert.” I thought that sounded nice. I spotted a magazine article on safety and thought “I do not have to read that as I am an expert.” I quickly recovered. The real problem with being called an expert is that many…
Recorded Webinars: Mechanical Component Failure Rates - Static vs. Dynamic Operation
The failure rates of certain mechanical components used in solenoid valves, actuators, and valves vary substantially depending on operation. For example, seals such as o-rings have fundamentally different failure modes when used in applications with frequent movement (dynamic) versus applications with infrequent movement (static). exida has accumulated over sixty billion unit operating hours of field failure data primarily from the process industries which was used in recent mechanical failure research. This webinar explains some results from this recent exida research where failure rates and failure modes of several mechanical components were established. This seminar is useful for anyone planning proof testing for mechanical SIF devices and anyone who wants to understand field failure data for mechanical devices.

Blog Entry: Ten Years Later
It’s hard to believe that the IEC61511 standard has been in existence since 2003, and most companies operating in the process, chemical, and refining industries (or any other hazardous process manufacturer) have adopted its practices. It’s also significant that any plants that were built back then with a Safety Instrumented…
