A 3-day training course providing both a theoretical and practical overview of the Tripod Beta methodology, enabling delegates to support and conduct incident investigations and analyses

About Tripod Beta

Tripod is a theory for understanding incidents and accidents, based on the Swiss Cheese model. It was developed to explain how and why incidents happen, and allow the root organisational causes and deficiencies to be uncovered and addressed. This 3-day training course will provide a theoretical overview of the Tripod Beta methodology and teach delegates how to apply this in practice, helping delegates uncover not just how an incident happened but also why it happened: the management controls that should have prevented it and the systemic organisational issues that can lead to future incidents.

Why the Tripod Beta training course?

  • The course is accredited by the Stichting Tripod Foundation, the custodians of the Tripod Beta methodology
  • Delegates will receive a free copy of the official Tripod Beta user guide, ‘Tripod Beta: Guidance on using Tripod Beta in the investigation and analysis of incidents, accidents and business losses’, worth £150
  • Successful delegates will be awarded Bronze Practitioners certification by the Stichting Tripod Foundation. Bronze Practitioners are recognised as being able to begin to use Tripod Beta and will be invited to undertake further accreditation to become a Gold Tripod Beta Practitioner.

Who should attend? 

Tripod Beta provides a structured way of thinking about why accidents happen and would be useful to anyone involved in managing risk and preventing unwanted events, such as:




HSE Advisors

Maintenance Engineers

Quality Assurance Engineers

Learning outcomes:

Upon completing this training course, delegates should be able to:

  • Gain an excellent theoretical understanding of the Tripod Beta methodology
  • Understand how accidents occur and implement a more proactive approach in preventing accidents at work
  • Assist with conducting structured, well-thought-out and deeper investigations with the established Tripod Beta methodology
  • Recognise the cost of incidents and the value of investigating unwanted events
  • Act as a Tripod Beta facilitator during incident investigations as a team member. 

Course outline:

Day 1:

  • Introduction
  • Nature of incidents
  • The Swiss Cheese model
  • Sequentially timed event plot

Day 2:

  • Review of Day 1
  • Tripod Beta core diagram
  • Immediate causes

Day 3:

  • Review of Day 2

  • Exam (Discussion and Feedback)


The EI Tripod Beta training course will be assessed by a 45 minute multiple-choice examination. Those who pass this knowledge assessment will be awarded Bronze Practitioner certification by the Stichting Tripod Foundation.


On successful completion of the Tripod Beta exam, delegates will achieve a Bronze Practitioner certificate, demonstrating their understanding of the Tripod Beta methodology. Bronze Practitioners will exhibit an excellent theoretical understanding and can begin assisting with low-level investigations.

Upon attaining Bronze Practitioner status, delegates will be invited to continue towards becoming an accredited Gold Tripod Practitioner and conduct more high-level and complex incident investigation and analyses.
