Just because the user…
Blog Entry: Know Your Human Error (Part I)
Increases in levels of automation and system complexity impact human error. Medical errors in hospitals and clinics result in approximately 100,000 people dying each year and cost the healthcare industry between $4B – $20B each year. In the petrochemical industries, operational error can cost upwards of $80M per incident. “Operator…
Training Course: Functional Safety Management Planning for IEC 61511
Safety planning is a specific requirement of IEC 61511 yet many organizations lack specific documentation on how functional safety is managed. This course reviews the requirements of the IEC 61511 Lifecycle and offers guidance for development of a written Functional Safety Management (FSM) Plan. It provides insights on how to…
Recorded Webinars: How Final Element Design and Selection Relates to Overall SIF Performance and Cost
Final elements play a key role in achieving a safe design, initial capital investment, and total operation cost. Understanding how final elements are designed and how they can fail enables users to make informed tradeoffs between upfront cost and lifetime costs. This webinar will review key information that should be collected and reviewed whether you are working with a new SIF design or managing installed equipment.
Attendees of the webinar will:
- Develop an understanding of key drivers to final element performance in safety systems
- Learn how final element design and documentation can drive maintenance costs
- Learn about new solutions such as exida’s eRAVA certification

Recorded Webinars: Do Bow Ties Have a Place in Alarm Management?
Bow Tie Diagrams, which have becoming increasingly popular over the last 20 years, provide a powerful and easy-to-understand way to visualize how a company controls risks to prevent major accident hazards. They illustrate the relationships between hazards, causes, potential consequences, the barriers in place to prevent the event or mitigate the results, and the degradation factors that might cause a barrier to fail. This webinar will provide an overview of the Bow Tie methodology and how it might be applied to alarm management. Content will be drawn from the new CCPS book “Bow Ties in Risk Management: A Concept Book for Process Safety” and other references. Specific examples include the Buncefield UK explosion / fire and the Gas Well Blowout and Fire at the Pryor Trust Well.
