Hazard Prevention: Using THESIS BowTie to Demonstrate ALARP

November 5, 2013 | 10:00 - 11:00 am CDT

The Bowtie analysis tool provides an efficient and effective way to portray and analyze major accident hazards at a facility. In a simple graphic, this tool will allow operations, engineering and management to easily understand the significant hazards at the site and the controls in place to prevent initiation and/or mitigate the consequences of a major accident.

As we consider how to prevent/mitigate all major accident hazards, pervasive questions are, "Have we done enough to protect people?" and "Have we done all that is reasonably practicable?" The facility must demonstrate for numerous accident scenarios that the controls in place are as low as reasonably practicable (ALARP).

In this webinar, we will illustrate how to demonstrate ALARP using the Bowtie method and how to efficiently calculate ALARP for numerous accident scenarios using the THESIS BowTie, a commercial bowtie analysis software used by several oil majors around the world. We will also demonstrate how to use the tool to perform cost/benefit analyses and evaluate "live" risk, thus enabling analysts to identify practical, cost-effective solutions for lowering risk.

What You Will Learn:

  • How bowties can be the core of the process safety management system
  • How to demonstrate ALARP with a bowtie
  • How to perform a cost/benefit analysis
  • Efficient evaluation of multiple accident scenarios

Presenter

Brad Eccles, PhD, is the Director of Process Safety Services at ABS Consulting in the UK. For the past 15 years, he has supported and managed a variety of projects to help industry identify its vulnerabilities to both natural hazards and man-made errors. Dr. Eccles experience includes performing natural hazard assessments of industrial assets to determine design weakness and identify retrofits for improvements, development of technical specifications for the safe operation of a facility, leading HAZIDs and developing risk registers for use by management in controlling site hazards, and enhancing the Bowtie Method for applications beyond the traditional safety use of the tool.
