Recorded Webinars: It’s Time!! Useful Life, MTTF, and Mission Time
There are several time parameters that are used in functional safety. Some of these parameters seem counterintuitive, e.g. a device with an average failure rate of 100 years but it fails after 10 years. How do these numbers align? Terms like useful life and Mean Time To Failure seem to contradict each other. In SIL verification calculations Mission Time is used, how does this fit in? This webinar will talk about the different time parameters and how they are used in functional safety. It will provide a basic understanding of the time parameters.

Recorded Webinars: Alarm Classification – Not all alarms are created equal!
Alarm classification is a process for grouping alarms that have a common set of requirements for areas like training, maintenance, testing, management of change, and reporting. It could, for example be used to identify Safety (Related) alarms that are used for functional safety purposes. Classification is also a required output of alarm rationalization per the ISA-18.2 and IEC 62682 alarm management standards. Despite this, many alarm management projects ignore classification or misinterpret what it is to be used for (it’s not the same as alarm priority or alarm type). Additionally the usage and benefit of Highly Managed Alarms (HMA) is not well understood.
This presentation will review the purpose of alarm classification, how to define alarm classes, and how to assign alarms to classes. It will also discuss the origin and purpose of Highly Managed Alarms, and their associated requirements. Lastly it will present application examples of classification (including “Safety Alarms”) and the benefits that can be realized by end users.
Blog Entry: The Importance of Process Safety to the next Generation of Chemical Engineers
Significant progress in process safety has been made by many companies and engineers around the globe. This progress is often overshadowed when a process safety accident hits the news. In December of 2007, a runaway reaction led to an explosion at the T2 Laboratories in Jacksonville, FL. The blast killed…
Recorded Webinars: Why having a good Safety Requirements Specification (SRS) for Machine Safety is a MUST
In machine safety the SRS is the foundation for the Safety Related Electrical Control System (SRECS) and should define ALL the requirements for the SRECS and its associated Safety Related Control Functions (SRCFs). As we have seen and learned from the process industry, all too often the SRS is rarely created or not taken seriously. When a SRS exists we often see poorly defined requirements, ambiguous or not easily understood functionality and missing or incomplete requirements are often seen when the SRS. The result of which leads to poorly implemented safety systems.
This webinar will highlight the importance of the Safety Requirements Specification (SRS). This webinar will also examine some of the weaknesses and will suggest how to improve the SRS further.
Anyone involved in the design, operation and maintenance of the SRECS should attend this webinar.

Blog Entry: How to become a world-class expert (the 10,000 hour rule)
In the book “Outliers”, Malcolm Gladwell popularized the notion that to become an expert in a field requires putting in 10,000 hours of practice. The emerging picture from studies of expertise is that ten thousand hours of practice is required to reach the level of mastery associated with being a…
Recorded Webinars: Integrating PHA and LOPA - An exSILentia® Product Demo
Two key tasks within the analysis phase of the safety lifecycle consist of conducting a Process Hazard Analysis (PHA) and a Layer of Protection Analysis (LOPA). The exSILentia® software supports both tasks with the PHAx™ and LOPAx™ modules respectively. This webinar will demonstrate how the information documented during a process hazard analysis can be transferred to the layer of protection analysis phase within the exSILentia software.

Recorded Webinars: Functional Safety Management (FSM) for IEC 61511
Functional Safety Management (FSM) is the “glue” that holds the Safety Lifecycle together in IEC61511. To be compliant, End Users need to have a FSM plan in place that covers ALL phases of the Safety Lifecycle: Analysis, Implementation & Operation. FSM is about the 3 Ps: People, Paperwork and Procedures and is specifically intended to help reduce and/or prevent systematic failures creeping into the lifecycle. The webinar explains why this is so important and highlights what needs to be done to achieve compliance. If you are an End User then you should find this webinar useful and informative.
