>Sparks from [the repair team's] welding work ignited a supply of fireworks, which had been stored next to the ammonium nitrate cache. Oh wow, I was wondering what the white-ish sparkles were just prior to the explosion. It was the fireworks cache going off, which then ignited the 2750 tons of Ammonium Nitrate. That's an immense amount of Ammonium Nitrate. I suspect one outcome of this will be a new ordinance/law will that disallow such large caches of explosive material from being stored in the same place. Rather it will have to be divvied up and distributed to holding facilities out of blast range of each other.
