Survey: Uncontrolled Ammonia Release Fault Tree

Please complete this survey by October 2, 2025 (5 pm).

In this survey, we will ask you to review the ammonia release fault tree and see if:

1. Any failure scenarios are missing; and
2. Any of the existing scenarios are unclear/ambiguous.

If you are not familiar with fault trees, please watch the short video tutorial that describes how to read a fault tree.

NOTE: We encourage you to complete this survey in one sitting, but if it's not possible, please keep this page open on your browser (it will not time out) until you are ready to submit it. Do not click on the survey link again as that will remove your current responses.
