FREE Webinars Announced - Alarm Rationalization & exSILentia 3.0

Alarm Rationalization - The Why and the How

It is well known that operator effectiveness is impacted by alarm system performance. Nuisance alarms, alarm floods, incorrectly prioritized alarms, and an overabundance of alarms make it much more difficult for the operator to detect, diagnose and respond to each alarm. Alarm rationalization, a proven alarm management technique and one of the stages of ISA-18.2’s alarm management lifecycle, can help address these issues.

Alarm Rationalization entails reviewing each alarm to ensure that it is justified and meets the criteria for being an alarm as defined in the alarm philosophy. It also involves defining the attributes of each alarm (such as limit, priority, classification, and type) as well as documenting the cause, consequence, and corrective action all in a Master Alarm Database (MADB).

In this webinar we will walk through the alarm rationalization process using exida’s new SILAlarm™ tool, which facilitates and records the results of alarm rationalization in a Master Alarm Database. We will also demonstrate how to apply alarm management best practices, taken from ISA-18.2 and EEMUA 191, to rationalization.

Encore Presentation: What’s new in exSILentia® Version 3 - FREE WEBINAR


With the release of Version 3, exida has expanded the capabilities of their flagship exSILentia® Safety Lifecycle Engineering Tool. This webinar will highlight enhancements to existing core functionality (SIL selection, SIL verification, Safety Requirements Specification) as well as introduce new features such as the revamped Graphical User Interface (GUI), which provides a spreadsheet-like overview and allows resizing and zooming within SIF windows. The webinar will also review the options available for upgrading from exSILentia v2.x and SILSuite:

SIL Selection Enhancements

• Work with multiple tolerable risk calibrations in a single project
• Create user-defined risk graphs and work with detailed frequency based targets (LOPA)

SIL Verification Enhancements

• Specify MooN architectures, partial stroke test intervals, and proof testing to account for “dead time”

New & Improved Capabilities

• Built-in tool for Process Hazards Analysis (PHA) and import of PHA results from 3rd party tools
• Automatic documentation of IEC / ISA 61511 compliance
• Embedded Safety Equipment Reliability Handbook viewer
• Action Item definition, assignment, and tracking
• Reference Library providing a common location for documenting project references
• Critical Device List for generating a where used list of all IPLs
• Project and SIF-based compare function
