Archive: Engagement opportunity on draft fault tree (Sep 2025)

As part of a comprehensive ammonia risk analysis, Technical Safety BC has drafted a fault tree to visualize different failure scenarios that can result in the uncontrolled release of ammonia from ammonia refrigeration systems. This fault tree is foundational for characterizing each ammonia incident in BC and helps us identify the most prominent scenarios to be addressed through our risk treatment plan. We would like industry's help to clarify and add any missing scenarios to this fault tree. The risk treatment planning process is scheduled for early 2026 and will reconsider existing actions and develop new risk treatment actions with industry experts to tackle the risk of ammonia release in BC.

We invite you to share your expertise by taking the survey (deadline: October 2, 2025, 5 pm) to help improve this fault tree.

If you are interested in attending a workshop on October 6, 2025 or October 8, 2025 to discuss any missing scenarios, please save these dates. Workshop registration can be completed at the end of the survey.
