News Item: Field Data Validation with Predictive Analytics Webinar
exida Webinars are back for 2015! This Wednesday (Jan 14) Dr. William Goble talks about Field Data Validation with Predictive Analytics. Upper and lower reasonability bounds for instrument failure rates can be established using a large set of FMEDA analysis results. These numbers can be used as a benchmark to…

Blog Entry: Seat-of-your-pants Software?
I’ve had software development folks tell me that the “just do it” approach is a valid lifecycle model for SW development. In their context, this means writing the code based on limited marketing and design information and then backfilling the requirements and design specifications to describe what was done. They…

Recorded Webinars: Safe Failures Aren’t Always your Best Friend
It is important that a plant does not encounter spurious trips, therefore disrupting process and losing time and money. Even more important is preventing the occurrence of an accident that could result in a loss of a plant, damage to the environment, or even loss of life.
This webinar will discuss how calculating the spurious trip rate is important and what can be done with that number (saving time and money). It will also cover dangerous detected failures, and how those play a part in the Safe Failure Fraction calculation and how they are compared to spurious trips. How simple mechanical devices and/or final elements can still partake in SIL ratings by means of the 2H method of evaluation without adding additional safe failures will also be presented.

Recorded Webinars: Financial Benefits of Creating an Effective Alarm Management Program
With increased focus on risk management and regulatory compliance, companies are looking to develop and implement alarm management programs that follow good engineering practices and improve operations. But where to start? This webinar will discuss a seven-step program, based on the ISA-18.2 alarm management lifecycle, which drives continuous improvement without overtaxing your plant resources. Specific topics include:
· developing an alarm philosophy
· alarm rationalization
· implementing designed suppression and alarm shelving
· creation of alarm response procedures
· monitoring & assessment of alarm system performance
It will also show the quantifiable business results that can be achieved from an effective alarm management program.
Blog Entry: Alarm Management Goes Global with the Release of IEC 62682!
The International Electrotechnical Commission (IEC) has just published the first edition of IEC 62682 “Management of alarm systems for the process industries,” a global standard on alarm management. This new global standard was developed based on the ANSI/ISA-18.2 standard of the same name, which was published in 2009. This means…
Blog Entry: Coming Apart at the Seams
Does your safety development process have a split personality? Do you “talk-the-talk but not walk-the-walk?” When crunch time comes for project completion, does the mantra “whatever it takes” matter more than following the process? Does your process peel away at the seams? Getting buy-in to a rigorous process for a…
Recorded Webinars: Are Your Proof Tests Effective?
Most engineers who design and verify safety instrumented functions (SIFs) understand how hard it is to design a manual proof test with high effectiveness (also called high proof test coverage).
Proof test coverage is an important variable in Safety Instrumented System (SIS) design that can impact risk reduction by an entire SIL level. This is shown in PFDavg calculations.
This webinar will explain proof test coverage, why this is an important safety parameter, and show that the real objective is to detect failures NOT detected by automatic diagnostics. It will also explain how SIS class products will have a lower proof test coverage and why a lower proof test coverage IS NOT a bad thing.

Blog Entry: How to Calculate Proof Test Coverage
Most engineers who design and verify safety instrumented functions (SIFs) understand how hard it is to design a manual proof test with high effectiveness (also called high proof test coverage). Those folks who understand that a proof test is not likely to detect all failures never use simplified equations that…
Recorded Webinars: The Key Variables needed for PFDavg Calculation
Three things must be checked when verifying that a given Safety Instrumented Function (SIF) design meets a Safety Integrity Level (SIL). These are:
· Systematic Capability or Prior Use Justification for each device meets the SIL level of the SIF
· Architecture Constraints (minimum redundancy requirements) are met
· A PFDavg calculation result is within the range of numbers given for the SIL level
A PFDavg calculation is the most common and perhaps the most important of the three performance metrics. A proper PFDavg calculation should be done based on a number of variables.
This web seminar will describe how all of these variables impact the PFDavg calculation and show the importance of each variable. The overall impact will be shown to be up to two SIL levels!
