Objectives

The objective of this training is to enable a pragmatic implementation of the cause tree method and to:

• Recall the objectives and context of the method's creation
• Describe the main steps of the implementation approach and the conditions to be met for success
• Put into practice, as a participant in a cause tree analysis and as a facilitator.

Program

The cause tree method was initially developed by the National Research Institute for Safety (INRS) to assist members of the Health, Safety and Working Conditions Committees (CHSCT) in identifying the proven causes of workplace accidents and proposing measures to reduce the risk of recurrence of such accidents. Not to be confused with the fault tree method, the cause tree method is now used as a powerful analysis method for feedback, applied to accidents but more broadly to near-misses or incidents. It also constitutes an excellent means of taking human factors into account for improving safety.

Objectives of the method

• Context of its development
• Links with other safety analysis and risk management methods

Presentation of the method

• The sequence of phases and tasks to follow
• Information to gather - Conditions for success
• Graphical aids - Construction of the tree

Utilization of the tree

• Qualitative and statistical analyses
• Accounting for organizational and human factors
• Synthesis: proposing risk reduction measures, sustaining and capitalizing

In-depth learning and practical application

• Experiential learning through facilitating participants on a second real-life case study from an industrial facility.
