There is not one thing that went right here. Every single thing you could do wrong was done.
AN should never be stored for long periods of time.
AN should never be stored near organics, flammables, or any heat generating item.
AN should never be stored in urban/residential areas.
AN should be stored in secured environments and in the smaller amounts separated by distance or berms to protect against a incidence causing the entire cache going up.
These idiots were criminally negligent on a scale rarely seen.
It would add a lot of force to your comment and its conclusion if you could cite a webpage making similar concrete recommendations from prior to this incident.
[I'm not doubting it exists-- I mean the above sincerely. Your point would be a lot more forceful if you showed it wasn't hindsight bias.]
That is an example of the kind of tables that exist that show what can be stored with and near what, and how much. Storing of explosives is well understood. They try these explosives in various quantities, near each other, with different heat and other effects applied. Through these experiments and through real-world accidents and catastrophes they know what shouldn't be done. What happened here was an example of what shouldn't be done.
This stuff is all pretty common sense. Since when do you need a "webpage making concrete recommendations" to know that storing thousands of tons of explosives in a single place in major city is a disaster waiting to happen?
