I’d argue no personal experience should be the basis for any safety procedure.

Safety procedures should be based on… what keeps people safe. Personal experience shouldn’t enter into it.

Say you need to evacuate a building. The evacuation plan should be based on building population, the number of exits, etc. etc. There are established policies for coming up with an evacuation plan to ensure they are safe and consistent.

Not “personal experience”.
