Fault Tree Development with Fault Trees Plus

Most risk systems today have risk matrices that are used for screening High-Risk events. Once identified, High-Risk events may require further analysis. Many books have been written on how to build Fault Trees to handle every eventuality. In this course, students will learn how to build and understand Fault Trees effective “on a napkin”. 

With this level of understanding, students will continue on to learn how to build a Fault Tree in a commercially available software package and interpret the accuracy of the software results. This course is an expanded version of the information presented in the Fault Tree and Event Tree basics class, but does not cover Event Trees in favor of greater depth for technicians and engineers closer performing the Fault Tree analyses for Safety Instrumented Systems (SISs) in the facility. 

This four (4) hour presentation provides basic instruction in the use of fault trees and event trees to determine risk. In this class, participants:

• Gain understanding of symbols typically used the make fault trees
• Gain understanding of basic math (i.e. multiplication and addition) typically used the make fault trees
• Learn to develop rationale for distinguishing between initiating events and contributing events
• Understand the difference between Frequency-based events and Probability-based events
• Understand the basic “roadmap” of a Safety Instrumented System (SIS)
• Brainstorm independent protection layers and their independence and effectiveness 
• Understand the relationship between risk, frequency and consequence
• Use the tool (fault tree/event tree) to solve PSM risk concerns
• Gain a functional knowledge of a commercially available Fault Tree software package by application of practical examples

Target Personnel:

• I/E engineers that work with SISs
• Process Engineers
• Technical personnel that support Process Hazard Analysis (PHAs)
• Site PSM core personnel who audit SIS systems
• PHA Facilitators
• Process Control Engineers participating in MOCs
• Process and Technical Managers and Leaders who manage maintenance and safety compliance
