In honor of the upcoming “Talk Like a Pirate” Day on September 19, I offer this lighthearted look at PIU assessment. Captain (C) “Ahoy me bucko! We be attemptin’ to get our transmitter design certified. It’s been shippin’ fer a few years now. We don’t got a lot of whatcha…
exida, the global leader in functional safety certification for the process industries, has certified the Rosemount Tank Gauging System from Emerson for functional safety, ensuring that it meets the functional safety requirements for Safety Integrity Level (SIL) 3 capability per IEC 61508: 2010. “Emerson has clearly demonstrated a very high…
The Failure Modes, Effects and Diagnostic Analysis (FMEDA) methodology was created in the late 1980s by engineers at exida in response to the need to obtain precise numbers for diagnostic coverage factors in programmable electronic systems. exida has continued to develop the method over the last 25 years into a technique that can predict failure rates, failure modes, and useful life for devices that contain electronic and/or mechanical components. The accuracy of the FMEDA prediction depends on the component database used in the FMEDA. The exida Electrical & Mechanical Component Reliability Handbook was developed using over 100 billion unit hours of field failure data from several different environments. This webinar will describe in some detail the FMEDA process and the field data comparison process.

This webinar describes the benefits of selecting IEC 61508 certified equipment for safety application in the process industries. The process used to certify both a simple device and smart, complex devices will be explained, as well as an in-depth description of the contents and information on the certificate. The webinar will also cover the benefits and limitations of a certification. Anyone wanting to understand the benefits of using certified equipment, or are interested in getting their devices certified should attend.
exida will be exhibiting and presenting at the 2014 Emerson Global User Exchange October 6-10, 2014 in Orlando, FL. Stop by Booth #323 during exhibit hours. Also, Dr. William Goble, Principal Partner and Todd Stauffer, exida Director of Alarm Management are among the presenters at this year’s event. Please see…

Alarms were originally shown on Piping and Instrumentation Diagrams / Drawings (P&IDs) to document hardware requirements for installation in a (panelboard) control room. This was important because there was limited real estate in the control room for the alarms (displayed on Panalarms and light boxes) and there was a real…
Have a formal process for tracking, recording, and classifying field shipments and failure returns. If your product was designed well in the first place, even if strict adherence to IEC 61508 was not followed, your field failure rate should be pretty low. Using Proven-In-Use (PIU) methodology will allow an assessor…
Loren Stewart, exida Safety Engineer, authored an article for the Summer 2014 issue of Valve Magazine . The article is titled “Evaluating and Proving SIS Safety Levels.” “Because the equipment used in a safety instrumented system 〈SIS〉 application has a critical job, such equipment must be carefully evaluated and justified.…
I was reading an incident report on the Chemical Safety Board (CSB) website the other day, where it was the conclusion of the reviewing team that the incident (which sadly resulted in a loss of life) was the direct result of a poor safety culture across the organization. If you…
exida, a global supplier of functional and process safety products, services and certifications has released a new version of PHAx™ , a tool that guides users through the Hazard and Operability study (HAZOP) process. PHAx helps identify and document hazards, hazardous events and associated sequence of events. It also documents…
