Blog Entry: Knowing Scope of Work (SOW)
There was a joke I heard many years ago that went like this… 3 workers were hired to run telephone lines. The first part of their job was to install the poles on which the wires would run. Each day, the foreman would ask the workers how many poles they…
Recorded Webinars: Functional Safety Assessment of Final Elements
IEC 61511 requires that Functional Safety Assessments be conducted at various points in the safety lifecycle. A thorough and well documented evaluation of final elements is not only a standards requirement but it is also one of the most important activities to ensure safety reliability and process availability. This webinar will present a straightforward process to achieve effective final element assessments.

Recorded Webinars: Nuisance Alarms – A menace to the Operator
Nuisance alarms are alarms that don’t meet the definition or purpose of an alarm according to the ISA-18.2 / IEC 62682 alarm management standards. Defined as alarms that annunciate excessively, unnecessarily, or do not return to normal after the correct response is taken, nuisance alarms can be the operator’s worst nightmare. They can clutter the alarm summary display, increase operator stress, desensitize the operator, and cause them to lose situation awareness. Nuisance alarms can create a culture where it becomes necessary and acceptable for operators to ignore alarms.
This presentation will discuss the dangers of nuisance alarms from a human factors point of view and will discuss techniques for eliminating them (rationalization), as well as handling them when they occur (alarm shelving). It will talk about how nuisance alarms affect operator decision making and how to change a culture where the ignoring of alarms has become standard practice.
Recorded Webinars: Reducing Project Lifecycle Cost with exSILentia®
Use of excel or an in-house tool may seem like the cheapest solution to support safety lifecycle tasks as outlined by IEC 61511. However, with each phase of the lifecycle comes a hefty to-do list that requires hours of preparation, discussion and documentation. As hours add up, the cost of the project increases. Use of exSILentia reduces the hours required for each task significantly by organizing and transferring key data from one step to the next, providing built-in failure rate data, performing design calculations and automatically generating necessary outputs. This webinar will outline how use of an integrated safety lifecycle tool can reduce overall project lifecycle cost.

Blog Entry: What do Nuisance Alarms, the 80-20 Rule, Mental Models, and More Have in Common?
Most everyone has heard of the “80-20 rule” . It asserts that for many situations, roughly 80% of the effects (outcomes) come from 20% of the causes (inputs). This rule was first proposed in the early 1900s by Vilfredo Pareto, who was an Italian engineer, sociologist, economist, political scientist, philosopher,…

Recorded Webinars: Automatic Application Program Creation based on Conceptual Design Information
The requirements for the application program of a SIF/SIS’s a logic solver are defined by the conceptual design and Safety Requirements Specification (SRS) of the SIF/SIS. Converting these requirements can be time consuming and can be prone to errors due to misinterpretation of the requirements. When the conceptual design and SRS are available in electronic format, the application program for the logic solver can be automatically generated. Apart from time savings due to automatic conversion, an additional benefit is the ability to start the logic creation process later in the project schedule avoiding costly redesign activities. This webinar will review the possibilities of automatic application program creation and demonstrate some early results of a development project the exSILentia team is working on.

Blog Entry: Functional Safety Standards - IEC 61508 vs. IEC 61511
IEC 61508 is considered a basic or “umbrella” standard for functional safety. It is generic and sometimes even vague. IEC 61508 was intended that various industry sectors provide their own specific standards and guidelines as needed. Here we can see the relationship between 61508 and other standards, such as 61513…

Recorded Webinars: Issues with Mechanical Cycle Testing in Static Applications Involving Stiction
In an industrial setting such as a chemical plant, oil refinery or a deep sea oil rig, there are safety instrumented systems in place which are designed to promptly bring about a safe shutdown of a process if certain hazardous conditions are detected. Such safe shutdowns frequently involve isolating a process fluid flow, often accomplished by the use of an ESD (Emergency Shutdown) valve. If the ESD fails dangerously, when a hazardous condition necessitating a shutdown occurs and the ESD does not perform its function when required, the worst case consequences can be catastrophic. To insure a safe process, each individual part of the process is looked at in depth to analyze the failure rate and failure mode data for each component in a safety instrumented function as a safety lifestyle. This webinar will look at the cause and effects of parts on an ESD binding or sticking and what that might do to your process.
